早在150年前,国外的科学家就提出了用燃料电池作为电源的设想,并且做出了样品。但由于受到当时技术条件限制,燃料电池工作效率过低,体积又太大,加上成本高昂,没能投入生产。但科学家们并未放弃改进燃料电池的研究工作,到了本世纪80年代,燃料电池的研制终于取得重要进展。燃料电池使用的燃料非常广泛,如氢、甲醇、液氨、肼、烃等。燃料电池也和普通电池一样,是通过电极上的“氧化—还原反应”使化学能转换成电能。但一般电池内部的反应物质消耗完后就不能继续供电,而燃料电
As early as 150 years ago, foreign scientists put forward the idea of using fuel cells as a power source and made samples. However, due to the technical conditions at that time, fuel cell work efficiency is too low, the volume is too large, coupled with the high cost, failed to put into production. However, scientists did not give up the research work to improve fuel cells. By the 1980s, the development of fuel cells finally made important progress. Fuel cells use a wide range of fuels, such as hydrogen, methanol, liquid ammonia, hydrazine, hydrocarbons and the like. Like ordinary batteries, fuel cells also convert chemical energy into electrical energy through an “oxidation-reduction reaction” on the electrodes. However, the general internal battery of reactive substances after consumption can not continue to supply, and fuel
