Abstract

An electrically conductive substrate is coated with a material containing an unsintered powder of a metal active for electrochemical proton reduction and colloidal silica and the said material is heated on the substrate successively in an oxidizing atmosphere and then in a reducing atmosphere. The electrode may be employed as a cathode for electrolytic production of hydrogen in an alkaline medium.
