PURPOSE:To enable mass production and cost reduction while at the same time to realize a flexible structure so as to secure sealing characteristics of an oxidant gas and a fuel gas by making one body structure with an upper manifold joined on top of a lower one with a separator between them. CONSTITUTION:An upper manifold 3 and a lower manifold 4 are positioned, respectively, on the periphery of the surface and the periphery of the back of a separator 2, and the respective manifolds 3 and 4, and the separator 2 are joined on top of another to form one body. Said manifolds 3 and 4 are press moulded of a thin plate to have corrugated cross sections forming a depressed parts corresponding to an oxidant gas supply flow passage hole 6 and exhaust flow hole 7, and a fuel gas supply flow passage 8 and an exhaust flow passage 9 of the separator 2, thereby forming oxidant gas flow passage holes 6 and 7, and fuel gas passage holes 8 and 9. At the same time, flanges 10 are arranged on the outer peripheral part, at said respective gas flow passage holes, and on the inner peripheral part thereof to join the manifolds 3 and 4 to the separator 2 by means of said flanges. Sealing characteristics of oxidant gas and fuel gas can be thus secured. |
