如今有一项技术,全世界各大企业每年都要投入总计数十亿美元的巨资竞相研究和开发,这就是“燃料电池”。燃料电池是利用氢和氧生成水的过程来产生电力的一种装置。所依据的原理,是“水电解反应”的逆反应。燃料电池一旦得到普遍应用,那 There is a technology nowadays. Every year, every major enterprise in the world invests a huge sum of billions of dollars in research and development. This is the “fuel cell.” A fuel cell is a device that uses hydrogen and oxygen to generate water to generate electricity. The principle is based on the “water electrolysis reaction,” the inverse reaction. Once the fuel cell has been widely used, that
