3、Fuel cells are a radically new and fundamentally different way of making electrical power from a variety of fuels. A fuel cell is an energy conversion device that produces electricity (and beat) by electrochemical combination of a fuel with an oxidant. A fuel cell consists of two electrodes (the anode and cathode) separated by an electrolyte .Fuel(e.g. hydrogen) is fed to the anode where it is oxidized and electrons are released to the external (outer) circuit. Oxidant (e.g.oxygen) is fed the cathode where electron are accepted from the external clrcuit. The electron flow (from the anode to the cathode through the external circuit produces direct-current electricity. The electrolyte conducts ions between the two electrodes. Practical fuel cell are not operated as single units units. they are connected in electrodes series to build voltage. A series of cell is referred to as a stack. Fuel cell stacks can be configured in series, parallel, both series and parallel, or a single units, depending on the particular application.

3、 燃料电池是一种全新的、从根本上不同于用各种燃料发电的方式。燃料电池是一种能量转换装置，通过燃料与氧化剂的电化学结合产生电能（和节拍）。燃料电池由两个电极（阳极和阴极）组成，由电解液分开。燃料（例如氢）被送入阳极，在阳极被氧化，电子被释放到外部（外部）电路。氧化剂（如氧气）被送入阴极，在阴极中接受来自外部电路的电子。电子流（从阳极到阴极，通过外部电路）产生直流电。电解液在两个电极之间传导离子。实际的燃料电池不是作为一个单元来运行的。它们串联在电极上以产生电压。一系列单元称为堆栈。燃料电池组可以配置成串联，并联，串联和并联，或单个单元，具体取决于具体的应用。<br>
