| 摘要 |
A narrow gap electrolysis cell has anode and cathode compartments (10, 11) divided by an ionically-permeable separator (12), such as an ion-exchange membrane or a fibrous diaphragm, and a current feeder grid (18, 19) in electrical contact with a surface-activated particulate electrocatalytic material (14, 15) carried on a face of the separator (12). 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 (16, 17) between the current feeder grid (18, 19) and the separator (12). |
