Fuel cells are efficient power generators that convert chemical energy directly into electrical energy with no moving parts. They have a variety of applications including off-grid power and mobile/static devices. Fuel cells work by using a catalyst to oxidize fuel like methanol and oxygen to produce electricity, water, and carbon dioxide. They require fuel, oxygen from air, and produce exhaust. Fuel cells automatically charge batteries when the voltage drops and turn off once charging is complete to provide reliable power and extend battery life. They can also power devices directly via an inverter or work in a hybrid system with other power sources like solar.

Fuel cells
The document presents a presentation on fuel cells. It discusses that fuel cells convert hydrogen and oxygen into water and in the process produce electricity and heat. Sir William Grove invented the first fuel cell in 1839. Fuel cells have several advantages over traditional power sources like high efficiency, low emissions, and no moving parts. While the initial costs are high, fuel cells can power vehicles, buildings, and portable electronics. Major organizations are working to further develop fuel cell technology to address the global energy demand.
Fuel cells
Fuel cells convert hydrogen and oxygen into water, producing electricity and heat in the process. Sir William Grove invented the first fuel cell in 1839, proving that electricity could be produced from reversing the electrolysis of water. There are several types of fuel cells including proton exchange membrane, phosphoric acid, solid oxide, alkaline, direct methanol, and molten carbonate. Fuel cells provide an efficient and non-polluting alternative power source without noise or moving parts. Applications include powering vehicles, buses, portable devices, telecommunications equipment, and someday powering homes. Major challenges include higher initial costs compared to conventional energy sources, though organizations worldwide are working to develop fuel cells further.
Fuel cells presentation
Fuel cells provide a promising alternative source of electricity. They convert chemical energy directly into electrical energy through an electrochemical reaction between hydrogen and oxygen, producing only water vapor and heat as byproducts. There are several types of fuel cells but proton-exchange membrane (PEM) fuel cells are well suited for transportation and small stationary power applications due to their high power density and low operating temperatures. A fuel cell consists of an anode and cathode separated by an electrolyte that allows protons to pass through but blocks electrons, forcing them into an external circuit where they can power devices before being reunited with oxygen at the cathode. While fuel cells have advantages over traditional combustion engines like higher efficiency and lack of emissions, challenges remain around infrastructure, cost and
Liquid electricity
The document discusses liquid electricity and vanadium redox batteries (VRBs). VRBs use liquid electrolytes containing vanadium ions that can reversibly shift between oxidation states, allowing the battery to be "recharged" by replacing the spent electrolyte with freshly charged electrolyte rather than conventional recharging. This overcomes limitations of traditional batteries for electric vehicles. VRBs were pioneered in the 1980s and have since been demonstrated on large scales for applications like grid energy storage. The document outlines the concept, history, operation, advantages and applications of VRB technology.
fuelcells++++-.pptx
Fuel cells convert chemical energy directly into electrical energy through electrochemical reactions. They consist of an anode, cathode, and electrolyte. In the process, hydrogen atoms are split into protons and electrons at the anode; protons pass through the electrolyte while electrons flow through an external circuit, generating electricity. At the cathode, protons and electrons combine with oxygen to form water. Fuel cells are more efficient and less polluting than combustion engines. Two major types are phosphoric acid fuel cells (PAFC) and polymer electrolyte membrane fuel cells (PEMFC), which differ in their electrolytes, operating temperatures, and applications. Fuel cells are used to power vehicles, buildings, and portable devices.
Fuel cell Technology used in Cars
Fuel cells directly convert chemical energy from hydrogen into electricity with only water and heat as byproducts. They provide pollution-free power and can be over twice as efficient as combustion technologies. Fuel cells can power many applications from portable devices to vehicles to buildings and have advantages of fewer moving parts and quiet operation. Key challenges are reducing costs and improving durability to compete with traditional power sources over the lifetime of the system.
Does ELECTRIC VEHICLES STOP CLIMATIC CHANGE.pptx
This ppt gives information that does electric vehicles stop climate change or not
The extraction process of lithium is very resource demanding and specifically uses a lot of water in the extraction process. It is estimated that 500,000 gallons of water is used to mine one metric ton of lithium.[5] With the world's leading country in production of lithium being Chile,[6] the lithium mines are in rural areas with an extremely diverse ecosystem.[7] In Chile’s Salar de Atacama, one of the driest places on earth, about 65% of the water is used to mine lithium; leaving many of the local farmers and members of the community to find water elsewhere.[8][9] Along with physical implications on the environment, working conditions can violate the standards of sustainable development goals. Additionally, it is common for locals to be in conflict with the surrounding lithium mines. There have been many accounts of dead animals and ruined farms in the surrounding areas of many of these mines. In Tagong, a small town in Garzê Tibetan Autonomous Prefecture China, there are records of dead fish and large animals floating down some of the rivers near the Tibetan mines. After further investigation, researchers found that this may have been caused by leakage of evaporation pools that sit for months and sometimes even yearsLithium-ion batteries contain metals such as cobalt, nickel, and manganese, which are toxic and can contaminate water supplies and ecosystems if they leach out of landfills.[11] Additionally, fires in landfills or battery-recycling facilities have been attributed to inappropriate disposal of lithium-ion batteries.
The primary industry and source of the lithium-ion battery is electric vehicles (EV). Electric vehicles have seen a massive increase in sales in recent years with over 90% of all global car markets having EV incentives in place as of 2019.[23] With this increase in sales of EVs and the continued sales of them we can see a significant improvement to environmental impacts from the reduction of fossil fuel dependencies.[24] There has been recent studies that explore different uses for recycled lithium ion batteries specifically from electric vehicles. Specifically the secondary use of lithium ion batteries recycled from electric vehicles for secondary use in power load peak shaving in China has been proven to be effective for grid companies.[25] With the environmental threats that are posed by spent lithium-ion batteries paired with the future supply risks of battery components for electric vehicles, remanufacturing of lithium batteries must be considered. Based on the EverBatt model, a test was conducted in China which concluded that remanufacturing of lithium-ion batteries will only be cost effective when the purchase price of spent batteries remains low. Recycling will also have significant benefits to environmental impacts. In terms of greenhouse gas reduction we see a 6.62% reduction in total GHG emissions with the use of remanufacturing

Fuel cell
A fuel cell is an electrochemical device that combines hydrogen and oxygen to produce electricity through an electrochemical reaction rather than combustion. It is more efficient than combustion-based engines. A fuel cell has an anode, cathode, electrolyte, and catalyst. At the anode, hydrogen splits into protons and electrons. Protons pass through the electrolyte while electrons flow through an external circuit. At the cathode, protons, electrons, and oxygen combine to form water. Fuel cells have applications in transportation, stationary power generation, and portable electronics due to their high efficiency, low pollution, and reliable operation. However, fuel cell technology still faces challenges related to cost, durability, reliability, and system size that must be addressed for

Recycling and Disposal on SWM Raymond Einyu pptx
Increasing urbanization, rural–urban migration, rising standards of living, and rapid development associated with population growth have resulted in increased solid waste generation by industrial, domestic and other activities in Nairobi City. It has been noted in other contexts too that increasing population, changing consumption patterns, economic development, changing income, urbanization and industrialization all contribute to the increased generation of waste.
With the increasing urban population in Kenya, which is estimated to be growing at a rate higher than that of the country’s general population, waste generation and management is already a major challenge. The industrialization and urbanization process in the country, dominated by one major city – Nairobi, which has around four times the population of the next largest urban centre (Mombasa) – has witnessed an exponential increase in the generation of solid waste. It is projected that by 2030, about 50 per cent of the Kenyan population will be urban.
Aim:
A healthy, safe, secure and sustainable solid waste management system fit for a world – class city.
Improve and protect the public health of Nairobi residents and visitors.
Ecological health, diversity and productivity and maximize resource recovery through the participatory approach.
Goals:
Build awareness and capacity for source separation as essential components of sustainable waste management.
Build new environmentally sound infrastructure and systems for safe disposal of residual waste and replacing current dumpsites which should be commissioned.
Current solid waste management situation:
The status.
Solid waste generation rate is at 2240 tones / day
collection efficiently is at about 50%.
Actors i.e. city authorities, CBO’s , private firms and self-disposal
Current SWM Situation in Nairobi City:
Solid waste generation – collection – dumping
Good Practices:
• Separation – recycling – marketing.
• Open dumpsite dandora dump site through public education on source separation of waste, of which the situation can be reversed.
• Nairobi is one of the C40 cities in this respect , various actors in the solid waste management space have adopted a variety of technologies to reduce short lived climate pollutants including source separation , recycling , marketing of the recycled products.
• Through the network, it should expect to benefit from expertise of the different actors in the network in terms of applicable technologies and practices in reducing the short-lived climate pollutants.
Good practices:
Despite the dismal collection of solid waste in Nairobi city, there are practices and activities of informal actors (CBOs, CBO-SACCOs and yard shop operators) and other formal industrial actors on solid waste collection, recycling and waste reduction.
Practices and activities of these actor groups are viewed as innovations with the potential to change the way solid waste is handled.
CHALLENGES:
• Resource Allocation.

Improving the viability of probiotics by encapsulation methods for developmen...Open Access Research Paper
The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.

Microbial characterisation and identification, and potability of River Kuywa ...Open Access Research Paper
Water contamination is one of the major causes of water borne diseases worldwide. In Kenya, approximately 43% of people lack access to potable water due to human contamination. River Kuywa water is currently experiencing contamination due to human activities. Its water is widely used for domestic, agricultural, industrial and recreational purposes. This study aimed at characterizing bacteria and fungi in river Kuywa water. Water samples were randomly collected from four sites of the river: site A (Matisi), site B (Ngwelo), site C (Nzoia water pump) and site D (Chalicha), during the dry season (January-March 2018) and wet season (April-July 2018) and were transported to Maseno University Microbiology and plant pathology laboratory for analysis. The characterization and identification of bacteria and fungi were carried out using standard microbiological techniques. Nine bacterial genera and three fungi were identified from Kuywa river water. Clostridium spp., Staphylococcus spp., Enterobacter spp., Streptococcus spp., E. coli, Klebsiella spp., Shigella spp., Proteus spp. and Salmonella spp. Fungi were Fusarium oxysporum, Aspergillus flavus complex and Penicillium species. Wet season recorded highest bacterial and fungal counts (6.61-7.66 and 3.83-6.75cfu/ml) respectively. The results indicated that the river Kuywa water is polluted and therefore unsafe for human consumption before treatment. It is therefore recommended that the communities to ensure that they boil water especially for drinking.

Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.

Water polluted by dyestuffs compounds is a global threat to health and the environment; accordingly, we prepared a green novel sorbent chemical and Physical system from an algae, chitosan and chitosan nanoparticle and impregnated with algae with chitosan nanocomposite for the sorption of Malachite green dye from water. The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.

- 5. How it Works • Fuel cells charge batteries fully automatically. • The integrated charge controller permanently monitors the charge level of batteries. • When the battery voltage drops below a predefined level, the fuel cell starts automatically and recharges the battery. • Once the battery is charged, it switches off again. This results in reliable, continuous power, reduces the amount of batteries needed, and extends the lifetime of the batteries since deep discharge damages are prevented. Via an inverter, you can also operate 230 V devices.
- 6. Fuel Cells and the Hybrid Principle Fuel Cells • Fuel cells use liquid fuel. • Every Fuel Cell employs DMFC (Direct Methanol Fuel Cell) technology which transforms methanol directly into electrical current. • That's a real advantage, especially for mobile applications, because liquid methanol is easy to transport anywhere in practical fuel cartridges. Hybrid Principle • Fuel cells also work in hybrid with other power generators. • For example, if a fuel cell is connected to an application that also has solar to it, the fuel cell only charges the battery if solar does not deliver enough energy – due to bad weather.
