The emergence of a Hydrogen Economy will require the development of new media capable of safely storing hydrogen in a compact and light weight package. Metal hydrides and complex hydrides, where hydrogen is chemically bonded to the metal atoms in the bulk, offer some hope of overcoming the challenges associated with hydrogen storage. The objective is to find a material with a high volumetric and gravimetric hydrogen density that can also meet the unique demands of a low temperature automotive fuel cell. Currently, there is considerable effort to develop new materials with tunable thermodynamic and kinetic properties. This tutorial review provides an overview of the different types of metal hydrides and complex hydrides being investigated for on-board (reversible) and off-board (non-reversible) hydrogen storage along with a few new approaches to improving the hydrogenation-dehydrogenation properties.
氢经济的出现将需要开发能够以紧凑且轻质的包装安全储存氢气的新型介质。金属氢化物和复合氢化物，其中氢在主体中与金属原子化学键合，为克服与氢储存相关的挑战提供了一些希望。目标是找到一种具有高体积和重量氢密度的材料，该材料还能满足低温汽车燃料电池的独特需求。目前，人们正在付出巨大努力来开发具有可调热力学和动力学性质的新材料。本教程综述概述了正在研究的用于车载（可逆）和非车载（不可逆）氢储存的不同类型的金属氢化物和复合氢化物，以及一些改善氢化 - 脱氢性能的新方法。
