利用自然界中的水制取氢。可以不受资源的限制。氢是一种清洁的能源,可以储存、输送,人类使用氢能不会破坏自然循环。因此,利用氢作为代替燃料的新能源具有很大的经济意义。据日本科学技术厅最近的预测,到2001年将能够实现氢能的生产。但是,随着氢的生产、使用规模扩大化和供给方式的改变,氢的储存、输送技术就会成为一个重要的课题。储存、输送氢的方法有两种:一种方法是把氢作为气体或液体用高压氢气瓶进行储存、输送;另一种是把氢作为金属氢化物进行储存、输送。在这两种方法中,特别令人注目的是把氢作为金属氢化物——即把氢固体化的方法。使用这种方法储存的氢的密度与液氢的密度差不多,甚至超过液氢的密度,从而可以大大缩小储氢容器的体积,提高储氢效率。把氢以固
Use of water in nature to take hydrogen. Can not be resource constraints. Hydrogen is a clean energy that can be stored, transported and used by humans without damaging the natural circulation of hydrogen. Therefore, the use of hydrogen as a fuel instead of new energy has great economic significance. According to a recent forecast by the Japan Science and Technology Agency, by the year 2001, hydrogen production will be achieved. However, hydrogen storage and transportation technologies will become an important issue with the expansion of hydrogen production and the change of supply methods. There are two ways to store and transport hydrogen: one is to store and transport hydrogen as a gas or liquid in a high-pressure hydrogen cylinder, and the other is to store and transport hydrogen as a metal hydride. Of the two methods, what is particularly notable is the use of hydrogen as a metal hydride - a method of solidifying hydrogen. The density of hydrogen stored by this method is similar to the density of liquid hydrogen even exceeding the density of liquid hydrogen, so that the volume of the hydrogen storage container can be greatly reduced and the hydrogen storage efficiency can be improved. Hydrogen to solid
