A fuel cell 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 fuel cell, 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。

In the simplest terms, a fuel cell combines hydrogen and oxygen in a process that releases electricity, heat and water.

FORBES: Beltway Bet: FuelCell Energy

Energy took an enormous step forward for the entire cleantech industry when it financed two fuel cell projects installed at electrical substations through the traditional rate setting process.

FORBES: Why the Bloom Suit Is Bad for America

Bacteria oxidize the organic matter and, in the process, produce electrons that run from the anode to the cathode within the fuel cell, creating an electrical current.
