Abstract: The invention relates to a process for the electrolytic production of hydrogen in an alkaline medium. The process consists in using a cathode, the active surface of which essentially consists of an oxide compound of the spinel type. The process is suitable, in particular, for the electrolysis of aqueous solutions of sodium chloride in cells with a permeable diaphragm.
