A solid polymer electrolyte electrode assembly comprising: a perfluorocarbon copolymeric membrane comprising two zones each having functional groups with the groups differing from one zone to the other; a hydrophylic perfluorocarbon copolymer composite anode prepared from a dispersion of conductive particulate substance and hydrophylic perfluorocarbon copolymer dispersed in solvating dispersion medium, said anode being coadhered to one membrane surface and consisting essentially of said conductive particulate substance partially coated with the hydrophylic perfluorocarbon copolymer, said copolymer having equivalent weight between about 900 and 1500; and a hydrophylic perfluorocarbon copolymer composite cathode prepared from a dispersion of particulate electrocatalytic compound and hydrophylic perfluorocarbon copolymer dispersed in solvating dispersion medium, said cathode being coadhered to the surface of the membrane obverse from said anode, said cathode consisting essentially of said particulate electrocatalytic compound partially coated with the hydrophylic perfluorocarbon copolymer, said copolymer having equivalent weight between about 900 and 1500.
