1327218 Fuel cells SIEMENS AG 10 Sept 1970 [11 Sept 1969] 43439/70 Heading H1B A fuel cell comprises a stack of components A, B arranged alternately, Figs. 3, 4, showing cross-sections along lines C, D and E, F, respectively, of Fig. 1. The stack is completed at each end by a similar-shaped component C, Fig. 5 to form a battery having components in the order CABAB ... AC. Resin is east around the stack to form an insulating casing (not shown). The reactants comprise oxygen which flows through apertures 20 in lugs 1, 6; hydrogen which flows through apertures 20 in lugs 3, 4 and KOH or H 2 SO 4 electrolyte which flows through apertures 20 in lugs 2, 5. Component A comprises diaphragms 7, 8, support structure 9 and sealing frame 10. Component B comprises diaphragms 11, 20, anode 13 and cathode 14, spacers 15, 16, sheet metal conductor 17 and sealing frames 18, 19. Certain of the apertures 20 have channels 21, 22, 23 as shown, for conveyance of the gas or electrolyte to the electrolyte spaces and gas spaces in the components A, B. Thus, channels 21 convey electrolyte, channels 22 convey hydrogen and channels 23 convey oxygen. The component C corresponds to the anode electrode of component B at one end of the stack and the cathode electrode of component B at the other end of the stack and, as shown in Fig. 5, corresponds to anode 13. The materials used for the components A, B, C may be silimar to those described for the components of the fuel cell of Specification 1,327,217, with the exception that when the electrolyte is H 2 SO 4 , the cathodes may consist of powdered activated carbon and the anodes may consist of powdered tungsten carbide. |
