| Abstract: | 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. |
