本工作以高压氢压缩为目的，研究了AB5型稀土基和AB2型TiCr2基储氢合金。开发了一对具有良好储氢性能的储氢合金Ml0.55Mm0.2Ca0.25Ni5(Ml：富La混合稀土；Mm：富Ce混合稀土)和(Ti0.97Zr0.03)1.1Cr1.6Mn0.4作为双级高压金属氢化物氢气压缩机(MHHC)用合金。利用开发的合金对，我们设计并建造了氢气容量为100L的MHHC原型，可以在2MPa左右的压力下从工业级氢气（纯度98%）生产压力为45MPa、纯度为99.9999%的高压超纯氢气。在压缩过程中，仅使用热水作为热源。研究了压缩特性并计算了热效率。
In this work, AB5type rare earth-based and AB2type TiCr2-based hydrogen storage alloys were studied for the purpose of high-pressure hydrogen compression. A pair of hydrogen storage alloys, Ml0.55Mm0.2Ca0.25Ni5(Ml: La-rich mischmetal; Mm: Ce-rich mischmetal) and (Ti0.97Zr0.03)1.1Cr1.6Mn0.4, with favorable hydrogen storage properties was developed as the alloys for a double-stage high-pressure metal hydride hydrogen compressor (MHHC). With the developed alloy pair, we designed and built a MHHC prototype with hydrogen capacity of 100L, which could produce high-pressure ultrapure hydrogen with pressure of 45MPa and purity of 99.9999% from industrial grade hydrogen (98% purity) at pressure of around 2MPa. During the compression procedure, only hot water is used as the heating source. The compression characteristics were studied and the thermal efficiency was calculated.
