摘　　要：金属氢化物是近年来在节能方面应用较为广泛的一种高性能材料。简述了热能-机械能转换系统的工作原理以及其具体的应用方式,如热机、氢压缩机和太阳能水泵等,存在合金储氢量低、易中毒、反应床传热传质性能不佳及整体效率低下等主要问题,并对氢化物热能-机械能转换系统进行了展望。Metal hydrides were one kind of the high performance materials applied widely at energy - saving aspects in recent years. In this paper the work principle is described and their applications of metal hydride based heat - power transforming system, such as thermal engine, hydrogen compressor and water pump etc., are s ,tumnarized. The main problems existed are low capacity of hydrogen storage, poor anti - poison, poor ability of heat and mass transfer of reactor and low efficiency. Moreover, the prospect for further investigation is presented.
