Cathode for electrolyzing acid solutions and process for producing the same

摘要

A cathode for electrolyzing acid solutions which comprises an electrically conductive metal substrate, a spray coated layer of a cathode active material containing tungsten, tungsten carbide or a mixture thereof in an amount of 10% by weight or more on the substrate, and an impregnation coated layer of 1 g/m2 or more of an acid-resistant fluorine containing resin on the outside surface of the coated layer of cathode active material, and a process for producing such.
