PURPOSE:To feed the reaction gas to each unit cell almost uniformly without being interrupted by a cooling plate by providing a rectifying means mitigating the flow of the reaction gas passing a porous plate from being disturbed by the side face of the cooling plate. CONSTITUTION:Plate bodies 11 exerting the rectifying function are provided respectively between a porous plate 5 and the side face of a cooling plate 2 in a manifold 3 located at the feed side, i.e., upstream side, of the reaction gas. Thereby, the gas stream flowing toward each plate body 11 side among the reaction gas stream uniformly flowing out from the porous plate 5 is divided into two streams by the top section of the plate body 11. They flow to a fuel cell laminated body 1 side along the outsides of the plate bodies 11 as shown by solid arrow lines in the figure. Since the plate bodies 11 are shaped in a roof shape, no vortex is generated on the gas stream flowing along the outsides of the plate bodies 11. Accordingly, the reaction gas can be sufficiently fed to unit cells adjoining to the cooling plate 2. |
