Transcript of Hydrogen Fuel Cells

Hydrogen Fuel Cell Conglomerate Hydrogen Fuel Cells How it works Advantages Conclusion Hydrogen is pumped through the fuel cell.
As it goes through it meets a membrane (PEM) that conducts protons and is impermeable to hydrogen electrons.
This means that the the electrons will be forced around the membrane and through an external circuit.
These electrons produce the power needed.
They then reform on the other side with oxygen gas, pumped in from the air, to produce water, the only bi-product The Chemistry 2H2 +02 Pollution rates drop drastically- due to zero carbon dioxide released by the fuel cell
Hydrogen fuel cells are not made in large power plants like other fuels, as they can be made efficiently in small scale factories
This is the fuel of the future- could effectively reduce the carbon problem that currently exists
Hydrogen fuel cell cars are quite safe, they have passed many safety standards and the hydrogen valve shuts off when impact or leak occurs. We need more funding in order to find a more cost efficient process of making and transporting the hydrogen fuel cells as a gas for our cars.
If more cost efficient ways to produce hydrogen fuel cells, hydrogen gas, and transport the gas are created, then it will become a new industry providing both countless jobs and a solution to the carbon problem. Drawbacks The creation of hydrogen fuel cells is very cost prohibitive and produces CO2
Hydrogen gas does not have the infrastructure in place to transport, and would be very costly
Transporting it would most likely produce CO2
The catalyst for the hydrogen fuel process is platinum, a costly and rare metal How Hydrogen Decreases Carbon Emissions Hydrogen Fuel cells do not release carbon dioxide
The only carbon footprint of hydrogen fuel cells is formed during in the creation of hydrogen gas. We are rejecting this bill because...
the technology is not ready for use by the public
Expensive to produce
Expensive to transport
However...
Funding is needed to support further research
Need to find a less expensive way to transport and produce hydrogen gas is needed
A new infrastructure is needed to get the hydrogen gas from source to where it is in demand
New Bill...
Hydrogen fuel cells will become the newest, greenest fuel in the United States
We support hydrogen fuel cells but further funding for research on this technology is needed so in the upcoming years it can be developed
Addressing the Carbon Problem...
Hydrogen fuel cells have the potential to serve as a major solution to the current carbon problem Rejecting the Bill 2H2O Why the other fuels won't work Ethanol...
takes away from the global food supply
flex-fuel
Lower MPG (lower energy release)
expensive to produce
Bio diesel...

Bad to breathe in
Engine power is reduced

Violent rattling in engine
releases carbon dioxide
can form smog
Harmful to the human body and the environment =0.68 volts of energy per fuel cell Anode: 2H2--> 4H+ and +4e- Cathode: O2+4H+ and 4e--> 2H2O Production and Transportation Production
current methods involve using fossil fuels to create electricity to electrocute water
burning fossil fuels to create power releases carbon dioxide, adding to the carbon problem
methods that could be used to create hydrogen without releasing carbon:
renewable energy as a power source
fermenting biomass
algae growth in water Transportation
current methods involve using pipelines, or using trucks with with either pressurized gas tanks or carrying liquified hydrogen
development of infrastructure is crucial
pipelines are the safest and most effective way to transport hydrogen
natural gas pipelines could be used The production and transportation of hydrogen fuel cells serves as a major challenge to the widespread use of this technology. The Carbon Problem Hydrogen Comparing Costs Hydrogen is measured by the kilogram 1kg=1 gallon of crude oil Using electrolysis, H2 is $1 per kilogram
Gasoline is around $3.50 per gallon
