1,274,338. Fuel cell. SIEMENS A.G. 30 June, 1970 [1 July, 1969], No. 31730/70. Heading H1B. A fuel cell structure comprises a synthetic plastics frame 1, e.g. polystyrene two metal grids 2 and 5, for example of nickel, welded to at least part of the periphery of the frame and extending over the interior thereof, one or more synthetic plastics grids 3, 4, e.g. of polypropylene, disposed between the metal grids and serving, in use, to support an electrolyte, one or more first coats 6, 7 on each metal grid each consisting of an ion exchanger preferably in fine-grain form suspended in a binder, and one or more further coat 8, 9 each consisting of a catalyst suspended in a binder. The ion exchanger may be inorganic or organic, e.g. powdered asbestos or a polymer or copolymer containing exchange groups, and the binder may be polyisobutylene, polystyrene or a polymethacrylic acid ester. The catalysts may be powdered Raney nickel and Raney silver. The fuel cell structures can be assembled to form batteries and the supply and discharge of reactants and electrolyte is effected through passages in the plastics frame. |
