汽车新能源的发展趋势
摘要:随着汽车保有量的增长和世界石油资源的日益减少;汽车尾气对城市空气污染加剧。各国都在千方百计降低汽车的燃料消耗和致力于代用清洁燃料和新能源的开发研究工作,以减轻对石油资源的过分依赖和汽车尾气对环境造成的危害。我国也已陆续出台了一系列鼓励节能环保和汽车新能源研发的政策,来缓解石油供需矛盾及环保问题。目前,醇类燃料、液化石油气、天然气等清洁能源在全世界范围内已得到较广泛的运用,并取得了一定的节能环保效果。二甲醚、氢燃料电池、生物柴油等新型清洁能源也正在研发之中。氢燃料电池作为一种高效零污染的电化学能量转换装置,已被认为是未来汽车最理想的能源。虽然实现向氢经济过度还需一个漫长的过程。但汽车必将进入氢动力时代。

Summary: Along with the automobile holds the quantity’s growth, and the world oil resource reduces day by day. The automobile exhaust pollutes the city air to be more and more serious. In order to reducing the excessively dependence of oil resource and the automobile exhaust which be harm for our environment, Various countries are all by any means possible to reducing the automobile’s fuel consumption and devoting to the substitutive clean fuel and new energy’s research and development. Out country also has appeared one after another series of policy which encouraging energy conservation\environmental protection and the new energy’s
research and development to alleviate the contradiction between petroleum supply and demand.
At present, the clean substitutive energy like alcohol type fuel, liquified petroleum gas, natural gas…ect had been used widely in world scope, and has obtained the certain effect. The new energy like dimethyl fuel cell, hydrogen fuel cells, biodiesel…ect are researching and developing. The hydrogen fuel cell takes one kind of highly effective zero pollution the electrochemistry energy conversion installment,had been considered will e the most ideal automobile energy in the future. Although there will be a long process to realize the hydrogen economy. But the automobile will get into hydrogen power for ages necessarily.
Keywords: China, automobile , the new energy, alternative energy source,
hydrogen power
