采用合金电沉积和复合镀技术，将ＮｉＭｏ合金和稀土储氢合金的微粒修饰到镍基表面作析氢反应的催化层．介绍了电极的表面形貌及电极性能的测试结果．结果表明，电极的催化活性和催化层抗氧化能力高于ＮｉＭｏ电极，说明吸附氢起到了保持电极催化活性的作用．所以，在催化层中引入稀土储氢组分，不仅提高了电极对析氢反应的催化活性，更重要的是显著增强了催化层的抗氧能力，延长了电极的使用寿命．
The alloy electrodeposition and composite plating technology, the NiMo alloy and rare earth hydrogen storage alloy particles modified nickel surface for the hydrogen evolution reaction catalyst layer. The surface morphology of the electrode and the test results of the electrode performance are introduced. The results showed that the catalytic activity of the electrode and the oxidation resistance of the catalytic layer were higher than those of the NiMo electrode, indicating that the adsorbed hydrogen played a role of keeping the catalytic activity of the electrode. Therefore, the rare earth hydrogen storage component introduced into the catalyst layer not only improves the catalytic activity of the electrode for the hydrogen evolution reaction, but also significantly enhances the antioxidant capacity of the catalyst layer and prolongs the service life of the electrode.
