Abstract
A cathode for use in the electrochemical production of hydrogen and process for making it which involves direct electrochemical cathodic action on a thermally produced adherent oxide on a nickel cathode surface. Examples include a nickel sheet thermally oxidized in air at 600.degree. C. for one hour and used directly in the production of electrolytic hydrogen and an iron sheet plasma sprayed with nickel to provide a surface containing thermal oxidation product of nickel and again used directly in the electrolytic production of hydrogen.
