ABSTRACT:
Electroplating is carried out in a nickel plating bath in which are dispersed active carbon particles supporting at least one platinum metal selected from the group consisting of platinum, rhodium, iridium, and palladium, thereby forming on an electrode substrate a nickel electrode active layer containing platinum metal-supporting active carbon particles and having such active carbon particles attached to a surface layer thereof, and thus producing a cathode exhibiting a high electrode activity and capable of stably sustaining a low hydrogen overvoltage for a long period of time.
