| 摘 要： | 研究了金属氢化物电极的活化过程及其。在电液中加入微量的活化添加剂，可显著加速ＭＨ电极的活化过程，提高电极的活化度和活率效率，并且采用Ｘ光电子能分析法对ＭＨ电极活化过程研究表明：添加剂的作用并非形成一层薄膜，阻止电极氢化，而只是在电极表面有少量Ｐｄ原子存在，

| Abstract: | In this article,the activation process and its mechanism of metal-hydride electrodes(MH) were studied.The activation process of MH electrodes quicken by the addition of small amounts of activator(PdCl 2) to elecrotrolyte solution,the activation efficiency and activation degree increase.The activation process of MH electrodes were studied by XPS method.The result show that there is small amount Pd atoms on the surface of MH electrodes.The Pd atoms have influence of catalysis on activation process,and can increase the surface consistency of hydrogen atoms.The diffusion of hydrogen atoms were accelerated,so the Pd atoms improve hydrogen storage capacity of MH electrodes. |
