ABSTRACT:
An especially efficient and durable electrolytic cell is provided by utilizing a combined cathode and diaphragm unit wherein the cathode is made by spray coating a ferrous metal substrate with a powder metal having lower hydrogen overvoltage than said substrate to form a protected cathode surface having a larger surface area than the substrate, and vacuum depositing fluorinated hydrocarbon polymer fibers onto the spray coated surface of the cathode to form a fibrous diaphragm securely adhered thereto. Preferably, the cathode surface is made with nickel and the fluorinated hydrocarbon polymer is selected from the group consisting of homopolymers of chlorotrifluoroethylene and copolymers of chlorotrifluoroethylene and at least one compatible monomer with units of chlorotrifluoroethylene accounting for at least 80 percent of the monomeric units of said copolymer.
