Abstract
PURPOSE: To keep low hydrogen overvoltage of a cathode for a long time, by subjecting the surface of the electrode base material having iron or nickel surface to electroless plating with nickel, by immersing the electrode in a soln. contg. thiourea in order to generate hydrogen gas, then by calcining the electrode in an atmosphere contg. oxygen.
CONSTITUTION: The surface of an electrode base material having surface formed at least with iron, nickel, or alloy of these metals is plated with Ni by electroless plating method. The electrode is then subjected to cathodic electrolysis in a soln. contg. thiourea to form hydrogen gas. The electrode is calcined at a temp. 400W 850°C in an atmosphere contg. oxygen. Hereby a cathode having low hydrogen overvoltage, and stable performance for a long time is manufactured.
