英国铁路正在研究采用燃料电池来为机车提供廉价电力的可能性。他们的化学部门已经对模型机车进行了成功的试验,并且认为实物机车也终将证明是技术上可能和经济上有利的。燃料电池是在一对电极上使燃料和氧相化合而产生电流——这样就把电解过程即液力在通过电流时分解为它的组成元素的过程倒转过来。到现在为止,燃料电池的发展是为了空间 British Rail is studying the possibility of using fuel cells to provide locomotives with cheap electricity. Their chemistry department has successfully tested prototype locomotives and believes that physical locomotives will eventually prove technically possible and economically viable. Fuel cells combine the fuel and the oxygen phase on a pair of electrodes to create a current - this reverses the process of electrolysis, which decomposes hydraulic fluid into its constituent elements as it passes through the current. Until now, the development of fuel cells is for space
