KATOD FOER ELEKTROLYS AV VATTEN ELLER EN VATTENLOESNING AV EN ALKALIMETALLHALID SAMT FOERFARANDE FOER FRAMSTAELLNING AV EN SAODAN KATOD

摘要

A cathode adapted for the electrolysis of water or an aqueous solution of an alkali metal halide salt because it gives prolonged lowering of hydrogen overvoltage is provided by an electrically conductive substrate bearing on its surface a coating produced by melt spraying an admixture of particulate nickel or cobalt and particulate aluminum and then leaching out the aluminum.
