2.  What is Fuel cell?
 What are the uses of it?
 Advantages of fuel cell
 Difficulties in fuel cell
 Alternate energy sources
 Future scope of fuel cells

3.  A fuel cell is a device that produces electricity
through a chemical reaction between fuel and
oxidant.

4. Let us see how does it works

5.  Zero emission.
 Gives maximum efficiency.
 Clean energy sources.
 Gives high thermal efficiency.
 Renewable energy source.
 No environmental impact.

6.  Most fuel cells operate silently, compared to
internal combustion engines.
 Fuel cells can eliminate pollution caused by
burning fossil fuels.
 Fuel cells have a higher efficiency than diesel or
gas engines.

7.  Hydrogen does not exist by itself in nature. Energy
must be expended to separate it from other, more
complex materials.
 Hydrogen is currently very expensive because it is
difficult to generate, handle and store.
 It can’t be stored at moderate temperatures and
pressures in a tank containing a metal-hydride
absorber or carbon absorber.

9.  NASA is the most famous supporter of hydrogen
fuel cells, this is because they use them to power
their rockets.
 United States has produced 19.8 billion pounds
of hydrogen, this is enough hydrogen to power
20-30 million cars.
 KSRTC is running their buses with fuel cell
vehicle.
