3. INTRODUCTION:-
Fuel Cell Overview…

4. What is a Fuel Cell?
An electrochemical device that combines hydrogen
and oxygen to produce electricity, with water and
heat as its by-product.
Electrochemical process, not combustion.
It is a clean, quiet and highly efficient process.
Two to three times more efficient than fuel burning.

5. How Do Fuel Cells Work?
 Redox Reaction:-
 Oxidation:-
 Anode side (an oxidation
reaction):
2H2 => 4H++ 4e-
 Cathode side (a reduction
reaction):
O2 + 4H+ + 4e- => 2H2O
 Net reaction (the "redox"
reaction):
2H2 + O2 => 2H2O

6. How Do Fuel Cells Work?

7. Types Of Fuel Cells:-
1.Proton Exchange Membrane (PEM)
2.Phosphoric Acid
3.Molten Carbonate Fuel Cell
4.Alkaline Fuel Cell
5.Regenerative Fuel Cells

8. Efficiency & Thermodynamics:-
 Automobile internal combustion engines
1) Inefficient – 25%
 Rechargable batteries (Lead-Acid or Nickel-Cadmium Batteries)
1) Run down quickly – 250 km
2) Recharged from external electrical source
3) Takes hours
 Fuel cells
1) Efficient – 80%
2) Create electricity chemically unlike combustion

10. Environment Effect:-
 Automobile engines: Gasolin = Pollutants
1) Co2 , Nox etc.
2)Causes Greenhouse effect and Smog
 Electric cars: Hydrogen fuel cell = Pollution free
1)Cleaner, Quieter, More Efficient
2)Product : Water vapour

11. Production Of Hydrogen:-
 There are three general categories of Hydrogen production:-
Thermal Processes
Natural Gas Reforming
Gasification
Renewable Liquid Reforming
Electrolyte Processes
Photolytic Processes

12. Application:-
 Transportation
 Stationary Power Stations
 Telecommunications
 Micro Power

13. Benefits Of Fuel Cell Tech.:-
 Reliability
 Efficiency
 Environmental Benefits
 Battery Replacement/Alternative
 Military Applications

14. Challenges To Fuel Cell Tech.:-
 Cost
 Sysyem Size
 Durability
 Safety

15. Conclusion:-
 The future fuel sources are environment-friendly.
 Throught the year these sources are available without affectiong
the environment.
 Using these fuels helps diminish global warming.
 Helps conserve natural resources.
