Fuel cells are electrochemical devices that can produce electricity and heat by chemically converting hydrogen and oxygen without combustion. Fuel cells can be used in many applications in the stationary, portable and transportation sectors. Fuel cell systems have numerous advantages over traditional power sources: greater fuel efficiency, fuel versatility, no emissions when using hydrogen as the primary fuel or less harmful emissions when using hydrocarbon fuels, and a strong potential for high reliability.

Hydrogen can be obtained from a variety of carbon-based fuels including natural gas and petroleum as well as renewables, through the use of electrolyzers. Oxygen used in the process is obtained from the air.
