2. FUEL CELLS
A fuel cell is a device that converts the chemical energy from
a fuel into electricity through a chemical reaction with oxygen
or another oxidizing agent.
Hydrogen is the most common fuel, but hydrocarbons such
as natural gas and alcohols like methanol are sometimes
used.

4. SOURCES OF HYDROGEN
•Oxidation: CH4 + 2 O2 CO2 + 2 H2
Still produces CO2!!
•Natural gas: 2 CH4 + O2 2 CO + 4 H2
Produces CO that must be converted to CO2!!

5. BENEFITS OF FUEL CELLS
Environmental Reasons
•Lowered emissions
Less noisy Increased Efficiency
•Up to 80% with pure Hydrogen
•With reformer about ~24-32%
•Gasoline ~20%
Flexible Technology
•Portable

6. SOME LIMITATIONS
 Hydrogen:
o Not readily available, must use other energy
sources to convert
o Difficult to store/distribute
 HighCapital Cost
 Non-technical barriers
o Could have dramatic impact

7. AUTOMOTIVE INDUSTRY & HYDROGEN
 Automotive industries such as honda, GM and toyota are
investing heavily on hydrogen fuelled cars as a future
technology.
 GM (general motors co.) and others are looking to
capitalize on the next generation of cars
 After enormous success of rivals like Honda and Toyota with
hybrid vehicles
 Rivals such as Toyota and Honda are already ahead of GM
and Ford

8. HYDROGEN FUELED BUS
•A 30 ft. Hydrogen Fuel cell powered transit bus
made by Ballard Power Systems in Canada.
•It has a 275 horsepower engine, and a range of 250
miles before requiring refueling.
•The only emission from this bus is warm, moist air.

9. HONDA FCX
 Honda has also built a hydrogen production and filling
station prototype.

10. FORD H2RV
H2 Internal Combustion Engine
hybrid with electric motor.
Driving Range 125 miles.

11. FUTURE
2015 – 2025- Substantial markets for
hydrogen-powered vehicles likely to
start developing
2020: 5 to 10 million hydrogen-powered cars
2030: 50 million hydrogen powered cars
2040: 150 million hydrogen-powered cars
