Hydrogen and oxygen are combined to produce power in fuel cell

Hydrogen and oxygen are combined to produce power in fuel cells. Fuel cells combine hydrogen and oxygen gases to produce energy. Often, they are compared to batteries as both convert chemically produced energy into electric energy that can be used just like any other forms of electricity (Science Applications International Corporation 35). Fuel cells do not however lose their charge as batteries do for as long as they receive fuel supply (hydrogen). This technology is increasingly being considered as a promising electricity source in future. Fuels cells operate maximally when supplied with pure hydrogen. While other forms of renewable energy like sun and wind are unable to produce continuous energy, they can be useful in production of electric energy and hydrogen which are stored for continuous production of energy via fuel cells (Slater 34).
