Abstract
A film-coated cathode is provided for the electrolysis of alkali metal halide solutions in the substantial absence of chromium ions. The cathode comprises a conductive substrate, such as titanium, steel, iron, or alloys thereof, coated with an adherent, porous film of a substantially nonconductive material having an average coating thickness of less than about 10.sup.3 microns. The nonconductive, film-forming material is further characterized as being chemically inert in the halate solution.
