摘要
贮氢电极循环伏安曲线氧化峰电流随电位扫描次数增加而减小，组成不同的电极，这种变化的程度也不同；具有较大放电容量的电极，其循环伏安曲线氧化峰面积较大、峰电流较高；速度扫描实验结果表明，贮氢电极循环伏安曲线氧化峰电流Ｉｐ与（ｖ：扫描速度）成线性关系，说明贮氢电极反应是一个扩散控制过程．
The properties of hydrogen storage electrode (MH electrode ) were investigated by cyclic voltammetry. The results have shown that the cyclic voltammograms of MH electrodes were affect ed by composition of hydrogen storage alloy. The anodic peak area is proportional to MH electrode discharge capacity. The peak current (Ip) was decreased by increasing sweeping number. The linear relationship between Ip and, v1/2 (v is sweeping rate) indicated that MH electrode reaction is controlled by diffusion proers. The diffusion of hydrogen atom in alloy is likely to be ratecontrolling step.
