Hydrogen fuel is a zero emission fuel which can be used in electrochemical cells and internal combustion engines to give power to vehicles and certain electric devices. It has been used as a fuel in fuel cell buses from many years. Hydrogen is also a very essential fuel used for the propulsion of aircraft. It is used as an energy carrier and can be used for a broad range of applications.
It can also be served as a primary and possible substitute to the really precious extinct and fossil fuels.Hydrogen is considered as an alternative fuel due to its ability to power fuel cells in zero-emission electric vehicles, its potential and capacity for domestic as well as industrial production and because of the fuel cells potential for high efficiency.
