1,238,603. Fuel cell construction. SIEMENS A.G. 31 Oct., 1969 [2 Nov., 1968], No. 53614/69. Heading H1B. An electrolyte chamber for a fuel cell is defined by two ion-permeable plates 5, which are gas-tight when impregnated with electrolyte, and a metal frame 2, situated between the plates and provided with electrolyte supply and discharge ducts 3 and 4, the chamber being filled with porous material 1. The plates may be of asbestos paper water-proofed at their edges where they contact the frame. The frame may be of nickel or stainless steel sheet 0À15-0À35 mm. thick and the porous filler nickel gauze. Ducts 3 and 4 may be hollow straps elongated perpendicular to the plane of the paper. Electrodes 6 and 7 may comprise pulverized catalytic material held in place by a gauze or perforated plate. 8 and 9 represent corrugated current collectors. Electrode frames 10 and 11 may be resilient. The cell may be run at 150-300‹ C. on H 2 and O 2 . Fig. 3 (not shown) shows a battery of cells comprising alternate electrode assemblies according to the invention and metal electrode frames containing a partition so that they define two gas chambers. The partition may be corrugated so that it touches both electrodes. The reactants and electrolyte may pass through the battery of cells in parallel. |
