摘要：

The morphology and surface composition of the hydrogen storage alloy are important factors that affect the performances of metal hydride (MH) electrodes. The performances of MH electrodes are effectively improved by the surface modification. The morphology and composition of the treated alloys were analyzed by XPS, ICP and BET. The effect of the chemical reducing treatment on the electrocatalytic activity of MH electrodes was discussed. It was found that the exchange current density of MH electrode increased markedly and the activation energy of electrode reaction decreased.
