Fuel Cell technology, one of the future application of energy supply for cars depends on hydrogen as a fuel and though expensive, is environment friendly.

1. FUEL CELL TECHNOLGY
 Direct energy conversion
(no combustion)
 Low emissions
 No moving part in the energy converter
 Quiet
 High availability of lower temperature units
[But, High Cost]

2. What is a fuel cell?
A fuel cell is an electrochemical energy conversion device that
converts hydrogen and oxygen, producing electricity and heat in
the process.
Fuel cells convert the chemical energy of a fuel directly and
very efficiently into electricity (DC) and heat, thus doing away
with combustion.

3. Stationary fuel cells can be used for backup
power, power for remote locations, distributed
power generation, and cogeneration (in which
excess heat released during electricity generation
is used for other applications).
Stationary fuel cells

4. Principle Of Fuel Cell:

6. Types of fuel cells:
 Alkaline fuel cell
 Direct methanol fuel cell
 Proton exchange membrane fuel cell
 Phosporic acid fuel cell
 Molten Carbonate fuel cell
 Solid oxide Fuel Cell

13.  Anode side : 2H2  4H+ +4e-
 Cathode side : O2+4H+ +4e- 2H2O
 Net reaction : 2H2+O2 2H2O

27. Advantages:
 Low to zero emissions
 Relieving the stress of overseas petrochemical
dependence.
 Not many moving parts in a vehicle (more mileage before
things start breaking)
 Hydrogen weighs less than gasoline (vehicles would not
need as much energy to move)
 Efficiency
 Reliability

28. Disadvantages:
 Hydrogen Supply.
 Expensive to equip a car with a hydrogen fuel cell.
 Hydrogen is expensive to make, store, and
transport.
 Anode is a platinum plate which is very expensive.

29. Conclusion :
Fuel cell reduces pollution caused by the
vehicles, nearly by 70%to 80% produced
by automobiles .Last but not the least ,it
is for every citizen to believe in the
power of renewable energy sources and
understand its importance .
