摘要
随着石油能源的枯竭和人类对于保护生态环境的日益重视,减少汽车尾气对空气污染发展新型环保绿色交通运输工具成为人类共识。汽油的热值是0.46*10^(8)KJ/kg,氢气的热值是1.43*10^(8)KJ/kg理论上氢气的热效能比汽油多3倍,汽油燃烧后产生的是CO_(2)、NO_(2)等温室气体,氢气只产生水,氢燃料电池车已成为汽车发展方向。本文对氢能源车的工作原理,整车布置,国内外发展现状做了浅析,并分析了重点突破方向分析研究,预测了发展前景。
With the depletion of petroleum energy,human beings pay more and more attention to the protection of ecological environment,and it has become a human consensus to reduce the air pollution caused by automobile exhaust and develop new environmental protection and green transportation tools.The calorifi c value of gasoline is 0.46*10^(8)kj/kg and that of hydrogen is 1.43*10^(8)kj/kg.Theoretically,the thermal effi ciency of hydrogen is three times higher than that of gasoline.After gasoline combustion,CO_(2),NO_(2) and other greenhouse gases are generated.Hydrogen only produces water.Hydrogen fuel cell vehicles have become the development direction of vehicles.This paper analyzes the principle,vehicle layout and development status of hydrogen energy vehicle,analyzes the key direction,and forecasts the development prospect.
