1. Hydrogen Fuel Cells
By: Kris Williams

2. Why Hydrogen Fuel Cells Are Needed
Fuel is becoming more expensive
Natural resources are being depleted
Fossil fuels contribute to greenhouse effect

3. Uses-if successful Large amounts of energy for
Fuel for cars-FCVs (fuel cell vehicles)
Electric energy-for stoves, washers, dryers etc.
Heat in homes

4. Hydrogen Most plentiful and simplest element in the universe
Fuel cells combine hydrogen and oxygen to give off energy and heat
Cheap, efficient, renewable

5. Setbacks Price of manufacturing Ability to Last/Reliability
Size of the system
Difficult to store

6. Hydrogen Future Act of 1996
The helped put futher research into action. It said
-research should be carried out for the “production, storage, transportation, and use of hydrogen”
-so that hydrogen can be used for “industrial, residential, transportation, and utility applications.”

7. Recent Developments in Technology
The H-racer
Toy car emulating how a real hydrogen powered vehicle would act
Works by converting
water to hydrogen by
energy from the sun

8. Recent Technology New Toyota Highlander FCHV
-550 miles on just one tank
-Traveled at a speed of 50 mph for 350 miles with AC on
British ENV (Emissions Neutral Vehicle) bike
-designed to drive 4 hours without refueling
-uses fuel cell generator and battery

9. First attempt at hydrogen powered car
1966
The Electrovan
Traveled 70mph
More Hydrogen Powered Vehicles

10. Fuel Cell System
A membrane electrode assembly (MEA) is placed between two flow-field plates
the anode and the cathode plates are each coated on one side with a thin catalyst layer.
They are separated by a proton exchange membrane The flow-field plates direct hydrogen to the anode and oxygen (from air) to the cathode.
When hydrogen reaches the catalyst layer, it separates into protons (hydrogen ions) and electrons.
The free electrons, produced at the anode, are conducted in the form of a usable electric current through the external circuit. At the cathode, oxygen from the air, electrons from the external circuit and protons combine to form water and heat.
