摘　　要：为了分析Fe替代Co的作用效果,对所制备的AB5型贮氢合金MmNi3.55Co0.75-xMn0.4Al0.3Fex(x=0、0.1、0.2、0.3、0.4和0.5)进行了电化学性能与结构测试。当x≤0.2时,Fe有利于合金综合电化学性能的提高;随着Fe含量增加,合金晶胞参数及体积(a、c、c/a和V)增加。In order to analyze the effect of substituted Co with Fc,AB5 type hydrogen storage alloys MmNi3.55Co0.75-x Mn0.4Al0.3 Fex （ x = 0,0.1,0.2,0.3,0.4 and 0.5） were prepared. Their electrochemical properties and structures were investigated. Fe had good effect to general electrochemical properties of alloy when x ≤0.2, the crystal parameters and volume（ a, c, c/a and V） were getting larger with the Fe content increasing.
