Corrosion behaviour of AB5-type hydride electrodes in alkaline electrolyte solution

Abstract

The corrosion rates of LaNi5 and LaNi3.55Co0.75Mn0.4Al0.3 hydride electrodes, soaked in alkaline electrolyte and under charge–discharge cycling, were investigated by linear polarization, Tafel polarization and a new method based on the difference between the charge and discharge capacities. The corrosion–inhibition by Ni in LaNi5 and the influence of… (More)
