美国汽车工业预测在21世纪燃料电池轿车将替代内燃机轿车。燃料电池不需要燃烧即可产生能量,这得益于氢和氧的化学反应。这个能量的产生过程要追溯到1839年,那时在航天技术中已得到应用。有一种碱性燃料电池用来推动航天飞机,该燃料电池需用大量 The US auto industry predicts that fuel cell cars will replace the internal combustion engine cars in the 21st century. Fuel cells produce energy without burning, thanks to the chemical reaction of hydrogen and oxygen. This energy generation process dates back to 1839 when it was applied in space technology. There is an alkaline fuel cell used to promote the space shuttle, which requires a lot of fuel cells
