from the 19th century.Since the usages and the development of fuel cells were coming in a long way.Fueling cells plays a main role for fuel vehicles.Here is some history of the fuel cells.Fuel cells were invented by William Grove in 1839.In 1950s proton exchange membrane fuel cells were invented by general electric.The first use of commercial fuel cells was in 1960’s by NASA’s for Apollo space mission.Alkaline fuel cell which is used by NASA for more than 80,000 hours in space craft and it has flown over 100 missions.In 1980’s fuel cells were used in submarine by US navy.In many cities bus were driven with this fuel cells. For fishing fleet from the diesel engine to fuel cells is have plan to converted in ICELAND.By the year of 2005 many car manufacturing commercial users were trying to produce their semi-commercial models with fuel cells.It is 60% efficient to convert power from the fuel.It can reduce pollutions,that can be produced by the burning of fossils fuels.fuel cells didn’t need fuels which are conventional like gas or oil.
