Abstract
An electrode for hydrogen generation can maintain a low hydrogen overvoltage for a long period of time even when electrolysis is conducted there not only with a low current density but also with a high current density. The electrode for hydrogen generation has a coating layer formed on a conductive base member by applying a material not containing any chlorine atom prepared by dissolving lanthanum carboxylate in a nitric acid solution of ruthenium nitrate and thermally decomposing the material in an oxygen-containing atmosphere.
