摘要 通过测量表面覆铜的贮氢合金电极的交换电流密度,初步讨论了覆铜层对贮氢合金的电催化活性的影响。结果表明,表面覆铜的MH电极的电催化活性大大提高,并且随镀铜工艺的不同而变化。 By directly measuring the exchange current density, the effect of surface copper coating of metal negative electrodes on electrocatalytic activity were investigated. It was indicated by experiments that surface copper coating results in increasing electrocatalytic activity which changes with different coating technologies.
