Abstract
PURPOSE: To provide a cathode having a strong surface layer and a low hydrogene overvoltage using a simple operation even when the cathode has a complicated shape, by forming a Co plating layer containing P on the surface of a cathode body comprising a cathode base material.
CONSTITUTION: The desired surface of a cathode body being a plate body, a net structure body or the like and comprising a cathode base material such as Fe, Ni or Ti is plate with a Co plating both having hypophosphorous acid ions and chlorine ions added. In this process, the concentration of hypophosphorous acid ions is in about 0.04W0.60mol/l, that of chlorine ions about 0.2W3mol/l. that of cobalt ions about 0.1W1.5mol/l and the pH value of the bath is in about 2W6.
