燃料电池车的发展和现状 燃料电池是一种将燃料和氧化剂中化学能变成电能的发电装置，只要不断地连续向电池供应燃料，燃料电池就能连续不断输出电能，不存在燃烧和充电－放电、再充电－放电反应过程，其能量转化率高，理论上可达100％，实用达到60-80％，是内燃机的2-3倍。并
Fuel Cell Vehicle Development and Current Status A fuel cell is a power generation device that converts chemical energy from fuel and oxidant to electrical energy. As long as fuel is continuously supplied to the battery, the fuel cell can continuously output electrical energy without burning and charging. Discharge, recharge-discharge reaction process, its high energy conversion rate, theoretically up to 100%, practical reach 60-80%, is 2-3 times the internal combustion engine. and
