Abstract

PURPOSE:To produce an electrode having less internal resistance by connecting big holes in a rough porous layer and small holes in a fine porous layer with a perforated foil or a powdery sintering material. CONSTITUTION:A rough porous layer 1 having equal through holes is prepared by piling nickel foils provided with small projections arranged at a constant interval, on its front and back sides being followed sintering, and cutting the piled nickel foils parallelly in non-distorted condition. Two nickel foils having 10,000 holes per 1cm<2> which have been prepared by etching and punching are piled and sintered, to yield a fine porous layer 2 having small holes whose largest hole size is 16mu. The rough porous layer 1 and the fine porous layer 2 are sintered through a foil having holes or a powdery sintering foil 6 thereby to obtain an oxygen electrode.
