Catalysts are used with fuels such as hydrogen or methanol to produce hydrogen ions. Platinum, which is very expensive, is the catalyst typically used in this process. Companies are using nanoparticles of platinum to reduce the amount of platinum needed, or using nanoparticles of other materials to replace platinum entirely and thereby lower costs.
With fossil fuel stores reducing, increasing fuel prices, and growing environmental concerns the demand for sustainable fuels and low carbon footprints has grown appreciably. This presentation talks about the hydrogen fuel cell concept and the technology behind the concept.

PEM Fuel Cell
A fuel cell is a battery that produces DC current and voltage
Most fuel cells use hydrogen which burns cleaner compared to hydrocarbon fuels
A fuel cell will keep producing electricity as long as fuel is supplied
The energy efficiency of fuel cells is high when compared to many other energy systems
There is great interest in fuel cells for automotive and electronic applications
There will be employment for technicians particularly in Ohio’s fuel cell industry.
A fuel cell vehicle (FCV) uses a hydrogen fuel cell to generate electricity, which powers an electric motor for propulsion, emitting only water vapor as a byproduct.
Hydrogen in fuel cell vehicles (FCVs) serves as the primary fuel that powers the vehicle. In a fuel cell, hydrogen reacts with oxygen from the air in an electrochemical process, producing electricity, water vapor, and heat. This electricity is then used to power the electric motor that drives the vehicle. The use of hydrogen in fuel cells offers a clean energy alternative, as the only emission from this process is water, making it an environmentally friendly option compared to traditional fossil fuels.
Fuel cells are known for their high efficiency, low emissions, and quiet operation, making them attractive for a wide range of applications, including transportation (such as hydrogen-powered vehicles), stationary power generation, and portable electronics.

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.
Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

AUTOMOBILES

2. INTRODUCTION TO FUEL CELL
A fuel cell is a device that converts the chemical energy
from a fuel into electricity, water and heat through a
chemical reaction with oxygen.
Fuel cells are different from batteries in that they require
a constant source of fuel and oxygen/air to sustain the
chemical reaction. Fuel cells can produce electricity
continually for as long as these inputs are supplied.
The first fuel cells were invented in 1838. The first
commercial use of fuel cells came more than a century
later in NASA space programs.
3. PARTS OF A FUEL CELL
Anode:
Negative post of the fuel cell.
Conducts the electrons that are freed from the hydrogen molecules so that they can be
used in an external circuit.
Etched channels disperse hydrogen gas over the surface of catalyst.
Cathode:
Positive post of the fuel cell
Etched channels distribute oxygen to the surface of the catalyst.
Conducts electrons back from the external circuit to the catalyst
Recombine with the hydrogen ions and oxygen to form water.
Electrolyte:
Proton exchange membrane.
Specially treated material, only conducts positively charged ions.
Membrane blocks electrons.
Catalyst:
Special material that facilitates reaction of oxygen and hydrogen
Usually platinum powder very thinly coated onto carbon paper or cloth.
Rough & porous maximizes surface area exposed to hydrogen or oxygen
The platinum-coated side of the catalyst faces the PEM.
4. HYDROGEN FUEL CELL
It splits the H2 molecule into two H+
ions and two electrons (e-)
On the other side, oxygen gas is
forced through the catalyst forms two
oxygen atoms, each with a strong
negative charge.
This attracts the H+ towards it.
The fusion results in, heat and
electricity.
The end product is water vapors and
electrons, that produce electricity.
Anode reaction:
H2 = 2H+ + 2eCathode reaction:
O2 + 2H+ = 2H2O
5. HYDROGEN FUEL CELL IN AUTO MOBILE
Heat and electrical energy is formed after the fusion of
electrons. Therefore, electrical energy is used to drive the
vehicle and we get water (H2O) as our exhaust. The heat
energy converts water into water vapor and thus our
exhaust from the vehicle is in the form of water vapor
which ultimately has no effect to the environment.
Thus, no pollution is created using this technology.
6. SOMETHING TO KNOW
The 1966 GM Electrovan
It is credited with being the
first hydrogen fuel cell car ever
produced. Though fuel cells have
been around since the early 1800's,
General Motors was the first to use a
fuel cell to power the wheels of a
vehicle.
7. TERMINOLOGY OF HYDROGEN FUEL CELL IN AUTOMOBILE
Fuel cells: A fuel cell is a device that converts the chemical energy into
electrical energy, water and heat through chemical reactions.
Hydrogen tank: A cylinder tank used for storing hydrogen in a car.
Traction inverter module: The traction inverter module is used to
convert supplied energy as efficiently as possible and make it available
to the drive motors in a suitable way.
Turbo compressor: A dynamic-type compressor is used for the
compression and injection of gases (oxygen).
Transaxle: An automotive part that combines the transmission and the
differential and is used on vehicles with front-wheel drive.
13. COMPARISON BASED ON CALORIFIC VALUE:
For hydrogen:
Higher calorific value: 141,790 kJ/kg
Lower calorific value: 121,000 kJ/kg
For petrol:
Calorific value: 48,000 kJ/kg
Heat generated from the hydrogen is more than that of petrol
or other gasoline fuels as the calorific value of hydrogen is
more. Thus, the power developed is more in vehicles
running on hydrogen fuel cells.
14. FUTURE SCOPE
The technology should be made cost effective.
Developing more safety features to the onboard hydrogen tank
and also at refilling stations by making the use of ‘Autolocking of supply valves by using hydrogen detector.’
In this technique, if the hydrogen is leaked from the cylinder
or supply line then hydrogen will be detected by the sensor
provided to it by sensing the tlv (threshold limit value) of
hydrogen.
When the gas is detected, the supply valves from the hydrogen
tank are closed. Thus, hydrogen gas leaking is thus avoided.
The other technique is to splash the water where the hydrogen
gas is leaked. But for this, there will be separate water storing
facility required. Thus, hazards expected from hydrogen gas
leaking are thus avoided
15. LIMITATIONS
For instance, you don't have a hydrogen pipeline coming
to your house, and you can't pull up to a hydrogen pump
at your local gas station.
Hydrogen is difficult to store and distribute, so it would
be much more convenient if fuel cells could use fuels
that are more readily available.
Technology is currently expensive.
16. CONCLUSION
Thus, it can be said that there will be a bright future if this
hydrogen fuel cell is put up to use in all vehicles by properly
considering the safety matter first.
And if this eco-friendly technology is used, the rate of
pollution is surely going to come down.
It is not only eco-friendly but, also serves to be a great fuel
source. Since the conventional sources of fuel may not prove
to be sufficient, there arises a need to develop a new
alternative source of energy. Although there are a few
problems related with the storage of hydrogen gas, which
might be overcome as the technology develops further.
“Hydrogen holds the great promise to meet our future energy
needs concerned with our environment.”
