摘要如今,随着世界人口的迅猛增长和经济的快速发展,化石能源的供应将不能满足的人类的需求,所以,寻找开发高效、可再生能源是惟一的解决办法。氢作为一种清洁能源,具有储量丰富、来源广泛、质量轻、能量密度高、热值高、“爆发力”强、来源广、品质纯洁、能量形式多、储存便捷、可以实现污染物的零排放等优点。氢气储存有物理和化学两大类。物理方法有:液氢储存、高压氢气储存等。化学法主要有:金属氢化物储存等。87204
金属氢化物储存可以循环的吸放大量的氢气,并且同时对氢气进行过滤,具有高安全性,储氢密度大、在常温常压下吸放氢、氢气纯度高、才做简单方便、占地面积小等优点,是一种无泄漏无能耗高效安的储运方式,是最有应用前景的储氢技术。本文对太阳能制氢—金属储氢系统进行了简单的介绍和设计。包括:储氢合金的选择,尺寸的基本参数以及结构的了解。

Abstract Nowadays, with the rapid development of economy and the rapid growth of world population, fossil energy reserves will not be able to meet the needs of human, so look for efficient and renewable energy development is the only solution。 Hydrogen as a clean energy, has the abundant, sources, light quality, high energy density, high calorific value, "explosive" strong, wide source, quality, purity, form of energy, storage more convenient, can realize the advantages of zero discharge of pollutants。 Hydrogen storage has physical and chemical two kinds big。 Physical methods are: liquid hydrogen storage, high pressure hydrogen storage, etc。 Chemical method mainly include: metal hydrogen storage, etc。 Metal hydrogen storage can be reversible put a large amount of hydrogen absorption, can for hydrogen purification at the same time, with high security, large hydrogen storage density, under atmospheric pressure with hydrogen absorption, high purity hydrogen, do the advantages of simple, cover an area of an area small, is a safe, efficient without energy consumption without leakage ways of storage and transportation is the most application prospect of hydrogen storage technology。 In this paper, the solar hydrogen production - metal hydrogen storage system has carried on the simple introduction and design。 Including: the choice of hydrogen storage alloy, the size of the understanding the structure and basic parameters。
Keywords:The hydrogen;Hydrogen storage alloy ;The metal hydrogen storage;The solar energy
