摘要：

Hydrogen diffusion coefficients in MlNi(3.75)Co(0.65)Mn(0.4)Al(0.2) alloy electrode as a function of state of charge (SOC) or temperature were determined by chronoamperometry. It is found that hydrogen diffusion coefficient decreases with the increase of SOC or the decrease of temperature. The activation energy for hydrogen diffusion in the alloy electrode with 50% SOC is evaluated to be 19.9 kJ/mol.
