Abstract

PURPOSE:To prevent any separation of carbon from a gas diffusing electrode, and increase the life of the electrode by impregnating a nickel sintered body for the electrode with a substance which can be carbonized by heating, before the impregnated nickel sintered body is carbonized so as to make carbon to be produced. CONSTITUTION:A net made of nickel wire is placed in the center of carbonyl nickel powder, before this is sintered in an atmosphere of hydrogen, thus a nickel sintered body being prepared. The nickel sintered body, next, is impregnated with a substance such as saccharose, blackstrap molasses, a tar or a synthetic resin that can be carbonized by heating, before thus impregnated nickel sintered body is dried and heated (the former substance turns to be carbon), thus a carbon layer being formed. The former heating preferably is carried out in an inert gas atmosphere containing at least one of oxygen and steam.
