Abstract
A gas diffusion electrode is used as a cathode for an electrolysis of an alkali metal chloride or an electrode in a fuel cell etc. A gas diffusion electrode has a porous layer made of a sintered mixture of a filler, a catalyst and a hydrophobic material which is formed by decomposing a pore forming agent selected from the group consisting of nickel, cobalt or iron salts of a carboxylic acids which is incorporated in a mixture of said filler, said catalysts and said hydrophobic material.
Claims17
A gas diffusion electrode having a conductive porous layer in contact with a conductive current collector, said porous layer being made by sintering a shaped mixture of a filler, a catalyst, a hydrophobic bonding material and at least one perforating agent selected from the group consisting of nickel, cobalt and iron salts of a carboxylic acid, the sintering of the mixture being carried out to decompose the perforating agent and to produce a porous bonded layer permeable to gas and repellant to water.
