Abstract of the Disclosure In a method of electrolyzing alkali metal chloride brine to form chlorine and alkali metal hydroxide, which method comprises feeding the brine to an electrolytic cell having an anode comprising anodic electrocatalyst separated from a cathode comprising cathodic electrocatalyst by a permionic membrane, said anodic electrocatalyst and said cathodic electrocatalyst both contacting said permionic membrane, and passing an electrical current from said anodic .. electrocatalyst to said cathodic electrocatalyst whereby to evolve chlorine at the anode ant hydrogen and alkali metal hydroxide at the cathode, the improvement wherein said anode comprises a pervious substrate having anodic electrocatalyst bonded thereto and bearing upon the permionic membrane, said cathodic electrocatalyst is bonded to and embedded in the permionic membrane, and the permionic membrane is a porfluorocarbon having functional groups chosen from the group consisting of - COOH, --CN2COF, --COC1, --COOR1, --COOM, and CONR2R3, where R1 is a C1-C10 alkyl group, R2 and R3 are chosen from the group consisting of hydrogen and C1-C10 alkyl groups and M is chosen from the group consisting of hydrogen, Na, and K.
