1,165,878. Fuel cell. BROWN, BOVERI & CO. Ltd. 15 March, 1968 [18 March, 1967], No. 12679/68. Heading H1B. A fuel cell, Fig. 2, comprises a plate, 4, of solid electrolyte having electrodes, 4a, 4b,formed on its faces, an annular gasket, 3, of asbestos felt surrounding and spaced from the edge of the plate, an annular member, 2a, 2b, of asbestos felt impregnated with an electrical conductor on each side of the gasket and in electrical contact with each electrode and a metal plate 1a and 1 or 1b adjacent each annular member so that the metal plate, annular and electrolyte plate form a gas space. In Fig. 2 the electrodes are plasma sprayed coatings of silver and nickel and the electrical conductor in the annular members is silver. The components may have holes, 15, for bolting them together, the bolts being surrounded with ceramic sleeves. They may also include bores, 11a-14a, and conduits, 11b-14b, for supplying the gases. A stack of such cells may be joined in series to form a battery, e.g. by using a common metal plate, 1, between 2 cells. |
