APPLICATIONS OF FUEL CELLS

FUEL CELLS:
ADVANTAGES OF FUEL CELLS:
 They produce zero or very low emissions,
especially green house gases.
 Their efficiency is very high.
 The individual cells can be stacked and connected
in series to generate higher voltages.
 The fuel cells are free form vibrations ,heat
transfers, thermal pollution etc .,
 They are reliable , maintainable and durable.
 Maintenance cost is very low.

DISADVANTAGES OF FUEL CELLS:
 Fuel cells do not store chemical energy.
 Handling of hydrogen gas is dangerous.
 Initial cost of fuel is high.
 Electrodes are expensive.
 Life time of fuel cell is not known accurately.


HYDROGEN-OXYGEN FUEL CELL:
ADVANTAGES OF H2-O2 FUEL CELLS:
 Hydrogen is a basic earth element and it is readily
available.
 It doesn’t produce harmful emissions.
 Hydrogen is a non toxic substances which is rare
for a fuel source.
 Fuel cells have higher efficiency than diesel or gas
engines.
