NARROW GAP ELECTROLYTIC CELLS Abstract A narrow gap electrolysis cell has anode and cathode compartments divided by an ionically-permeable separator, such as an ion-exchange membrane or a fibrous diaphragm, and a current feeder grid in electrical contact with a surface-activated particulate electrocatalytic material carried on a face of the separator. The particulate material has cores of a corrosion-resistant material preferably valve metal particles or sponge, or compounds thereof, as well as asbestos fibres and fibres of ion-exchange copolymeric perfluorocarbons, coated with a platinum-group metal catalyst in metal or oxide form. The surface-activated particles may be at least partly carried by a flexible electronically conductive foil between the current feeder grid and the separator. (Fig. 1)
