The impedance spectra of Zr(V{sub 0.4}Ni{sub 0.6}){sub 2}, Zr(V{sub 0.2}Mn{sub 0.2}Ni{sub 0.6}){sub 2}, Zr(V{sub 0.2}Mn{sub 0.2}Ni{sub 0.55}Si{sub 0.05}){sub 2} alloys have been investigated. An equivalent circuit for the reaction of an MH electrode is proposed. The results reveal that: (1) the additions of Mn and Si have significant effects on the reaction resistances of the alloys; (2) Ni powder is an appropriate additive material in the manufacturing process of an MH electrode; (3) the amounts of Ni powder in the alloy electrode also should be considered in the practical utilization.
