Abstract

The cyclic voltammetric behavior of MmNi3.03Si0.85Co0.60Mn0.31Al0.08-based metal hydride electrode was studied in alkaline electrolytes at various temperatures (303, 308, 318 and 328 K). Electrochemical parameters such as limiting current density and corrosion potential were determined at these temperatures. The corrosion potential became more negative with increasing temperature. Hydrogen diffusivity was also found to increase with increasing temperature. From electrochemical discharge experiments, it was concluded that the charge transfer process was the rate-determining step.
