摘　　要：研究了混合稀土中常见杂质锌、铁、镁对贮氢电极材料的贮氢性能、电化学性能等的影响。结果表明：它们的存在使合金的吸氢平台压力及吸氢量有所改变，同时电极的大电流放电特性也发生变化，但对其放电容量影响不大。The influences of the usual impurities of Zn, Fe and Mg in mischmetal on the hydrogen storage and electrochemical properties of a hydrogen storage electrode are investigated. It is shown that these impurities result in the changes of hydrogen adsorption platform pressure and amount and also cause the alteration of the characteristics of high discharge destiny;however, they have no obvious effects on the discharge capacity.
