摘要
采用富Ｌａ混合稀土金属（ＭＬ）对ＭＬＮｉ（３．８５－ｘ）Ｍｎ（０．４）Ｃｏ（０．７５）Ａｌｘ（ｘ＝０．１～０．５）五元贮氢合金吸放氢性能进行了测试，并计算出其热力学参数。结果发现Ａｌ含量增加，贮氢量下降，添加Ａｌ分解压降低，有利贮氢。
Mischmetal ML (La-rich) was used to study MLNi(3.85-x)Mn(0.4)Co(0.75)Alx(x=0.1￣0.5) hydrogen storage alloys. Their activation processes and hydrogen absorptiondesorption perfomancas were investigated. The results show that the increase of aluminum content in the alloy can lower the plateau pressure and decrease the amount of hydrogen absorbed. It seems that MLNi(3.85-x)Mn(0.4)Co(0.75)Alx(x=0.1￣0.3) alloys are prospective.
