A monopolar membrane electrolytic cell is comprised of a plurality of anodes wherein each anode is comprised of a first foraminous surface and a second foraminous surface positioned in parallel and spaced apart, and a frame enclosing the first and the second foraminous surfaces. The frame has two side members, a top member, and a bottom member attached to the foraminous surfaces. A chamber is formed between the foraminous surfaces and bounded by the frame. Conductor rods pass through one of the side members of the frame into the chamber, the conductor rods being spaced apart from the foraminous surfaces. Foraminous conductive connectors are positioned in the chamber and attached to the conductor rods and to the foraminous surfaces; a plurality of cathodes wherein each cathode is comprised of at least one foraminous surface, and a frame which encloses the foraminous surface. The cathodes are alternatingly interleaved with the anodes; a plurality of sheets of cation exchange membrane material, each of the sheets being pressed between each opposite pair of the anodes and the cathodes. The cation exchange membrane material is comprised of a blend of a first fluorinated polymer which contains sulfonyl functional groups and a second fluorinated polymer which contains carboxylic acid functional groups; the cell has raw material supply conduits and product withdrawal conduits communicating with the interior of each of the anodes and the cathodes; means for supplying electric current to the anodes and removing electric current from the cathodes are provided, and pressing means provided for pressing the anodes and the cathodes together to form a substantially fluid-tight cell.
