A fuelcell is a device that uses a source of fuel, such as hydrogen, and an oxidant to create electricity from an electrochemical process.
燃料电池是一种利用某种燃料（举例：氢）和氧化剂通过电化学过程产生电能的装置。

In a fuelcell, chemical energy from hydrogen and oxygen (or air) is directly converted to electrical energy, i. e. without a combustion process.
在燃料电池，氢气和氧气的化学(或空气)直接转换为电能的，即没有一个燃烧的过程。
