A fuel cell is an electrochemical cell that converts the potential energy from a fuel into electricity through an electrochemical reaction of hydrogen fuel with oxygen or another oxidizing agent. Fuel cells are different from batteries in requiring a continuous source of fuel and oxygen (usually from air) to sustain the chemical reaction, whereas in a battery the chemical energy comes from ...

Hydrogen fuel is a zero-emission fuel when burned with oxygen. It can be used in electrochemical cells or internal combustion engines to power vehicles or electric devices. It has begun to be used in commercial fuel cell vehicles such as passenger cars, and has been used in fuel cell buses for many years. It is also used as a fuel for the propulsion of spacecraft.

Hydrogen er det letteste grunnstoffet, og den vanligste isotopen består av kun ett proton og ett elektron.Under STP danner hydrogen en to-atomig gass, H 2, med et kokepunkt på bare 20,27 K og et smeltepunkt på 14,02 K. Under ekstremt høyt trykk, som finnes i sentrum av gasskjemper, går hydrogen over til å bli et flytende metall (se metallisk hydrogen).
