    摘要： A fuel cell stack and method of manufacturing a fuel cell stack having a highly anti-corrosive property. The fuel cell stack includes a plurality of cells constructed by interposing an electrolyte membrane electrode assembly between the first and second separators. The first and second separators define gas passages on from both sides of the electrolyte membrane electrode assembly, and a gas manifold is in fluid communication with the gas flow passages through the plurality of stacked cells. Manifold openings for defining the gas manifold are formed in the first and second separators, and the opening areas of the manifold openings are differently sized. The manifold opening inner peripheral end of the first separator has a larger opening area, and is welded to the second separator to form a manifold welding portion.

    摘要： An anode (11a) and a cathode (11b) are provided on either side of an electrolyte membrane (11). A first separator (2) is disposed so as to face the anode (11a), and a second separator (3) is disposed so as to face the cathode (11b). A first sealing member (12) is disposed between the electrolyte membrane (11) and the first separator (2), and a second sealing member (13) is disposed between the electrolyte membrane (11) and the second separator (3). The cross-sectional shape or rubber hardness of the sealing members (12, 13) is varied according to a deformation amount generated in the electrolyte membrane (11) by a sealing reactive force. More specifically, in a site where the deformation amount of the electrolyte membrane (11) is large, either the contact area between the sealing member (12) and the electrolyte membrane (11) is increased, or the rubber hardness of the sealing member (12) is reduced. In so doing, deformation of the electrolyte membrane (11) caused by the sealing reactive force is suppressed, and the sealing performance of a fuel cell (10) is improved.
