减少交通工具及其动力装置给周围环境带来的损害,是今后几十年科学家和工程师们的主要课题.特别希望把改善环境和采用气态燃料结合起来,其中氢气占有很特殊的地位,因为氢气资源实际上是取之不尽的,其实它就是几乎占地球表面四分之三的水.氢气是由电解水制取的,在燃烧过程中形成水蒸汽,从大气中制取时还生成氮氧化物. Reducing damage to the environment from vehicles and their power units is a major issue for scientists and engineers in the decades to come, and it is particularly desirable to combine the improvement of the environment with the introduction of gaseous fuels, with hydrogen playing a special role because hydrogen In fact, it is inexhaustible resources, in fact, it is almost three-quarters of the Earth’s surface water.Hydrogen is made by the electrolysis of water, the formation of water vapor in the combustion process, from the atmosphere when the system also generates nitrogen Oxide.
