Abstract

Alkaline water electrolysis by using various oxides was investigated for a compact hydrogen generator. It was found that La_0.6Sr _0.4CoO₃ exhibits high activities to both cathode and anode reactions in water electrolysis and shows good chemical stability. The overpotential for H₂ formation is almost the same with that of Pt. Anodic overpotential of La_0.6Sr_0.4CoO₃ is much smaller than that of Pt. Therefore, by using La_0.6Sr _0.4CoO₃ as an electrode, a Pt-free electrolysis cell for alkaline water electrolysis with high efficiency is realized. Stable electrolysis performance of the cell using La_0.6Sr _0.4CoO₃ for both anode and cathode was sustained over 250 h examined.
