| Abstract: | in order to improve the dynamical properties of cathodic hydrogen storagealloys, the effects of Mm addition on the electrochemical behavior of laves phase alloyshave been investigated. XRD, EPMA and metallographic studies showed that in the alloysome decentralized and infinitely small Mm-NI alloy particles formed. The alloy surfacereacted with strong alkaline electrolyte solution and disproportionately produced looseMm(OH)3 which benefited the electro catalysis of Ni cluster to hydrogen electrode reaction. |
