The generation efficiency of fuel cells changes greatly when the load changes which greatly affects the efficiency of fuel cell powered electrical vehicles.
燃料电池的发电效率随着输出的变化会有很大改变，对燃料电池电动车的运行效率产生很大的影响。
The fuel cell can achieve improved efficiency for electricity generation with no increase of the resistance of the metal separator, even when it is operated at a low temperature.
这样的燃料电池，即使在低温下运行时金属隔板的电阻也不会增大，可提高发电效率。
