燃料电池是1939年由英国科学家培根首先研制成功的,20世纪50年代后期特别是宇航事业的发展,使燃料电池的研究得到快速发展。美国阿波罗宇宙飞船上曾经使用过 H_2—O_2燃料电池,该电池的生成物水还可以供宇航员饮用。当前人类为开辟新的能源,减少对环境的污染,正加紧对燃料电池的研制。严格地讲,燃料电池属于一次性电池(少数也可充放电使用),但一般的一次性电池的正、负极活性物质是固体并放在电池内,用完后不能补充,容量较小,而燃料电池的活性物质是放在电池外储罐中的气体或液体,只要将气体或液体的活性物质源源不断地输
The fuel cell was first developed by British scientist Bacon in 1939. In the late 1950s, especially the development of the aerospace industry, the research on fuel cells developed rapidly. H_2-O_2 fuel cells have been used on Apollo spacecraft in the United States. The resultant water from this battery can also be used by astronauts for drinking. At present, mankind has stepped up its efforts to develop new energy sources and reduce pollution to the environment. Strictly speaking, the fuel cell is a disposable battery (a small number can also be used for charge and discharge), but the normal disposable battery positive and negative electrode active material is solid and placed in the battery, can not be used up, the capacity is small, and The active material of a fuel cell is a gas or a liquid placed in a battery outside the tank, as long as the gas or liquid active material is continuously input.
