摘要: 采用富La混合稀土金属(ML)对MLNi3.85-xMn0.4Co0.75Alx(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.Abstract: Mischmetal ML (La-rich) was used to study MLNi3.85-xMn0.4Co0.75Alx(x=0.1~0.5) hydrogen storage alloys. Their activation processes and hydrogen absorption-desorption performances 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 MLNi3.85-xMn0.4Co0.75Alx(x=0.1~0.3) alloys are prospective.
