Method of manufacturing electrodes for fuel cells

摘要

A method of manufacturing an electrode for batteries using hydrazine or the like as fuel, which electrode has an electrode substrate carrying a layer of copper and nickel or nickel boride as a catalyst and a metal of the platinum group deposited on said layer, said method including a step of immersing the electrode substrate into a solution of a salt of the metal of the platinum group to deposit said metal by utilizing the difference in ionization tendency between said metal and nickel, whereby the amount of metal of the platinum group to be added is reduced and an electrode is obtained which is highly active and has a long service life.
