论述了电动汽车（EV）、电动汽车用镍氢电池、锂离子电池、质子交换膜燃料电池（PEMFC）、固体氧化物燃料电池（SOFC）及相关材料的研发现状、产业化前景，指出以电动汽车代替燃油内燃机汽车，以氢能代替碳基燃料，是当前运输业的主要发展方向。

The status, R & D tendency and commercialization prospect of electric vehicles (EVs), their power sources (nickel-metal hydride batteries, lithium ion secondary batteries, proton exchange membrane fuel cell, solid oxide fuel cell) and relevant battery (cell) materials are elucidated. Electric vehicle as a viable alternative to petrol-engine cars and hydrogen energy as an alternative energy source to carbon-based fuels is an important development direction for transportation.
