燃料电池（FC）可以通过使用膜和电极组件（MEA）使氢与氧发生电化学反应来产生电力。换句话说，阳极和阴极之间的氢气压力差可以通过电化学过程产生电力。相反，当我们从外部电源向MEA供电时，我们可以根据“浓差电池”的原理将氢气从低压阳极泵送或分离到高压阴极。来自FC的耗尽的氢可以通过本文提出的氢分离泵回收，或者低压氢可以通过本文提出的氢压缩泵泵送到高压氢。在本研究中，我们初步测试了氢分离泵和氢压缩泵，并展示了其良好的性能。利用改进的FC仿真模型建立的氢泵仿真模型对试验性能进行了分析，试验结果与计算结果吻合较好。(c)2006 Elsevier B.V.保留所有权利。
Fuel cells (FC) can produce electricity through electrochemical reaction of hydrogen with oxygen with the use of a membrane and electrode assembly (MEA). In other words, the hydrogen pressure difference between the anode and cathode can produce electricity via an electrochemical process. Conversely, when we supply electricity to MEA from an external power source, we can pump up or separate hydrogen from the low pressure anode to the high pressure cathode according to the principle of the "concentration cell". The depleted hydrogen from the FC can be recovered by the hydrogen separation pump proposed herein, or low pressure hydrogen can be pumped to high pressure hydrogen by the hydrogen compression pump proposed herein. In this study we preliminarily tested the hydrogen separation pump and hydrogen compression pump, and demonstrated their good performance. The tested performances were analyzed with the use of our simulation model of a hydrogen pump, which was made by modifying our FC simulation model, and the test results agreed well with the calculated results.
