Abstract:
A fuel cell pack including a plurality of cells each having a membrane, and a cathode at one side of the membrane and an anode at another side of the membrane, collector plates contacting the cathode and the anode, respectively, in each cell, and an electrical connection member for electrically connecting adjacent cells, at least two cells being provided, the cells being evenly disposed in a plane with an enclosed, contiguous hollow space interposed between two adjacent cells, the electrical connection member being positioned in the enclosed, contiguous hollow space, the fuel cell pack comprising:a porous fuel diffusion member contacting the anode of each cell; a porous air contact member contacting the cathode of each cell; an anode end plate and a cathode end plate disposed at the side of the anodes of the cells and at the side of the cathodes of the cells, respectively; fuel supply and discharge means for supplying fuel toward the anodes in the enclosed, contiguous hollow space and discharging the fuel; a fuel flow stopper disposed at a portion at the part of the cathodes in the enclosed, contiguous hollow space, the fuel flow stopper preventing fuel flowing at a portion at the part of the anodes in the hollow space from flowing toward the portion at the part of the cathodes in the enclosed, contiguous hollow space; and a sealing member for sealing the anodes of the cells in said enclosed hollow, contiguous space and the portion of the hollow space corresponding to the anodes.
