(JP2569541-B2)      A separator for a fuel cell is claimed. The whole surface is corrugated and a flow path aperture is created in the first side of a peripheral part for supply and exhausting of an oxidising gas and fuel gas. A gas passes uniformly into a central section through the aperture. One corrugated plate forms a passage for this. The separator has a central section, the cutout part giving the magnitude of the electrode. The separator has a frame board consisting of two sheets (12a,12b). Each of the flow path apertures for supply and exhausting of the oxidisng gas and fuel gas corresponds to the peripheral part. The first and second first sheets of the frame board enclose the corrugated plate (11) from both sides. The peripheral part of the frame board is adhered to the peripheral part of the corrugated plate. The flow path aperture for supply (5) and exhausting (7) of oxidising gas of the corrugated plate periphery part connects with the flow path aperture for supply and exhausting of the oxidising gas of the two sheet frame board. Likewise the fow path apertures for supply (6) and exhausting (8) of the fuel gas of the corrugated plate and the frame board connect. In the single side and on the opposite side of the corrugtead plate, only the flow path aperture for supply and exhausting of the fuel gas is connected. In the joint section of the corrugated plate and the frame board, the clearance betwee both is joined and sealed with a filler (14) acting as a junction material.    USE/ADVANTAGE -   In fuel cells. The corrugated plate is easy to manufacture by pressing even when the required size of the plate is large. No welding is necessary to attach the corrugated plate to the frame board sheets. As no welding is required, distortion caused by welding is no longer a problem. Sealing nature is improved and the demands on the flatness precision of the frame board can be relaxed. Since the corrugated pltae and frame board are supple, sealing performance is improved.
