The document discusses different types of renewable and non-renewable energy sources. It focuses on fuel cell technology, describing how fuel cells work to produce electricity through a chemical reaction of hydrogen and oxygen without combustion. Specifically, it outlines the basic components and functions of proton exchange membrane fuel cells and solid oxide fuel cells. The advantages of PEMFCs include low operating temperatures and short startup times, while SOFCs do not require expensive catalysts. However, both have challenges such as materials durability at high temperatures for SOFCs and heat and water management for PEMFCs.

fuel prices are rising and resources dwindling
food, transport and electricity costs are affected by fuel prices
the atmosphere is becoming more and more polluted
carbon dioxide contributes to climate change and the greenhouse effect
There are 4 main parts

A review on fuel cell and its applicationseSAT Journals
Abstract With the increase in the demand of electrical energy now it is the time to think for the alternate source of energy. In order to mitigate the demand of electrical energy and to create pollution free environment the fuel cell acts as an alternate solution. The fuel cells are very much similar to an ordinary dry cell or battery. It has an electrode, some chemical material and an electrical circuit to give the supply to an external circuit. Due to absence of rotating devices they are quite simple and efficient in nature. This paper describes about the working methods of fuel cells and their future and economic growth.

Automate machine for rescue operation for childeSAT Journals
Abstract
The aim of the project is to rescue of trapped child in to the boar well by continues monitoring & supply of necessary items to survive using technical method. These bore wells in turn have started to take many innocent lives. Bores which yielded water and subsequently got depleted are left uncovered. Small children without noticing the hole dug for the bore well slip in and get trapped. To aid in such rescue we have proposed a system. The Methods to keep a child alive in a bore should take in to consideration the lack of oxygen, increased temperatures and humidity, which produces hyperthermia. These problems are addressed with fresh air delivery with or without oxygen. A hand-powered equipment to deliver fresh air inside bore is being designed. This method brings down temperature and delivers fresh air. Visualizing the child is made possible with infrared waterproof cameras and a portable high resolution TV Monitor. This is light weight machine that will go down into the bore well pipe and save the child life systematically. This machine will go down the bore well and perform the action. This robot type machine can stay alive trapped body from bore well until parallel hall will be dug up which will work as minimum amount of time and save the child life systematically.

Sachpazis:Terzaghi Bearing Capacity Estimation in simple terms with Calculati...Dr.Costas Sachpazis
Terzaghi's soil bearing capacity theory, developed by Karl Terzaghi, is a fundamental principle in geotechnical engineering used to determine the bearing capacity of shallow foundations. This theory provides a method to calculate the ultimate bearing capacity of soil, which is the maximum load per unit area that the soil can support without undergoing shear failure. The Calculation HTML Code included.
2. Renewable energy
“Energy from a source that is not depleted when used”.
Renewable energy can be used over and over again
It can be reused like the same states.
Examples
Air gives us wind energy.
Water gives us hydral energy.
3. Non Renewable Energy
Non-renewable energy is energy that cannot be used again once it is used.
Energy something that cannot be reused once it has depleted.
Examples
Minerals, coals, fossil fuels
4. Types of renewable energy
There are some types of renewable energies which are given below but we
will mainly discuss the scope of fuel cell.
Wind energy
Solar energy
Hydral energy
Fuel cell technology
5. Fuel cell
A fuel cell produces electricity through a chemical reaction, but without
combustion.
A fuel cell is an electrochemical device that combines hydrogen and
oxygen to produce electricity, with water and heat as its by-product.
In its simplest form, a single fuel cell consists of two electrodes - an anode
and a cathode - with an electrolyte between them.
6. Fuel cell working
The reactions that produce electricity happen at the electrodes.
Every fuel cell has two electrodes, one positive, called the anode, and one
negative, called the cathode.
Fuel goes to the anode side, while oxygen (or just air) goes to the cathode
side.
A chemical catalyst speeds up the reactions here.
7. Fuel cell applications
Fuel cells are being considered for a wide range of applications.
PEMFC have the most promising applications to buses, recreation vehicles,
and lightweight vehicles.
These are being used in portable computers.
power systems for trains, ships and vehicles
supplying electrical power for residential or industrial utility.
This type of fuel cell is used in stationary power generators with output in the
100 kW to 400 kW range to power many commercial premises around the
world.(PAFC)
9. Proton exchange membrane fuel cell
“The proton exchange membrane fuel cell (PEMFC) uses a water-based, acidic
polymer membrane as its electrolyte, with platinum-based electrodes”
PEMFC cells operate at relatively low temperatures (below 100 degrees
Celsius).
Due to the relatively low temperatures and the use of precious metal-based
electrodes, these cells must operate on pure hydrogen.
10. Advantages and disadvantages
Advantages of PEMFC
working temperature ~80C
short startup time
can work at high current densities compared to other cells.
Disadvantages
Low temperature
Unefficient to use rejected heat for cogeneration of additional powers
Difficult heat and water management limit the operating power densities
11. Solid oxide fuel cell
a fuel cell that derives its energy directly from the oxidation of a solid or
ceramic material called an electrolyte.
A typical SOFC uses a solid ceramic electrolyte placed between anode
(positive, and made of carbon-graphite) and cathode (negative) electrodes.
When air, fuel, and heat are provided, the device produces electricity.
12. Advantages and disadvantages
Advantages
Releasing negligible pollution.
Since all the components are solid, as a result, there is no need for
electrolyte loss maintenance and also electrode corrosion is eliminated.
Since SOFCs are operated at high temperature, expensive catalysts such as
platinum or ruthenium are totally avoided.
Disadvantages
Fuel cell operates on high temperature, so the materials used as components
are thermally challenged.
The relatively high cost and complex fabrication are also significant problems
that need to be solved.
