摘　　要：通过对贮氢材料吸放氢过程进行分析,自行设计安装了一套测量贮氢材料贮氢性能的装置。该装置可用于测试贮氢材料的PCT曲线,吸放氢动力学曲线以及循环寿命。利用该装置对LaNi5贮氢材料进行了贮氢性能测试实验。结果表明:该测试装置设计合理,测试方法可靠;LaNi5贮氢材料具有很好的吸氢动力学性能,但是其循环寿命较差,经60次吸放氢后容量衰减较多。Through analysis of the hydriding/dehydriding process of hydrogen storage material, an apparatus for measuring hydrogen storage properties was designed and set up. This apparatus can be employed to measure the curves of the hydriding/dehydriding dynamics, the PCT curves and the cycle life for hydrogen storage material. The hydriding/dehydriding properties of LaNis was acquired by this apparatus. The result indicates that this design principle of apparatus is reasonable; LaNi5 has excellent hydriding kinetics properties however, the cycle life is rather bad because of quite fast capacity decrease after 60 ab-/desorption cycles.
