(1).It has a higher efficiency over ordinary cell and also eco friendly.
(2).The H2O produced by this used by astronauts for drinking purposes.
(3).Fuel cells do not escape any exhaust.
(4).Unless an organic fuel like a hydrocarbon or an alcohol is used, there will be no greenhouses gases like carbon dioxide, because hydrogen combustion only produces harmless water.
(5).Fuel cells could be used in countries with little oil and make them less dependant on costly imported oil.
(6).Hydrogen-oxygen fuel cells create water and since the hydrogen will have to be made from abundant water supplies in the long run, it is effectively a renewable resource, unlike fossil fuels like petrol or diesel.
(7).Fuel cells are much more efficient than fossil fuel power stations or costly chemical batteries etc. because the electrical energy is generated directly from the chemical reaction.
(8).In fossil fuel power stations, motor vehicles, coal/gas fires etc. too much energy is lost as waste heat.
