Abstract

A method is disclosed forming a membrane over a standard diaphragm cell foraminous electrode and may comprise the steps of suspending a matting material in a liquid medium, inserting a foraminous electrode into the suspension, vacuum forming a layer of the suspended matting material over the surface of the foraminous electrode so as to substantially reduce the porosity of the foraminous electrode material, applying to the surface of the foraminous electrode with the matting material thereon; a layer of thermoplastic material which includes particles of perfluorosulfonic acid resin in the sulfonyl fluoride form, baking the foraminous electrode with the layers in place until the thermoplastic material is fused into a thin and uniform film on the surface of the matting material which is substantially permeable to hydraulic flow and hydrolyzing the perfluorosulfonic acid resin to change the sulfonyl fluoride form to the cation exchange sulfonic acid form. The forming of the membrane over a standard diaphragm cell electrode assembly eliminates substantial cathode costs involved currently for converting the diaphragm electrolytic cell to a membrane electrolytic cell.
