摘要： Flow guides forming an inlet channel are formed on a surface of a metal separator of a fuel cell. The flow guides overlap a section of an outer seal provided on the other surface of the metal separator. When a load is applied to the flow guides and the overlapping section in a stacking direction of the fuel cell, the flow guides and the overlapping section are deformed substantially equally in the stacking direction to the same extent. The line pressure of the flow guides and the line pressure of the overlapping section are substantially the same. The seal length L1 of the flow guides and the seal length L2 of the overlapping section are substantially the same.

摘要： A seal member is formed integrally on surfaces of a metal separator of a fuel cell. The seal members include an outer seal provided near the outer edge of the separator, and an inner seal spaced inwardly from the outer seal by a predetermined distance. When a load is applied to the outer seal and the inner seal in a stacking direction, the outer seal and the inner seal are deformed substantially equally in the stacking direction to the same extent.

摘要： A fuel cell that is small and light has separators having communication ports for reaction gases and cooling medium that are provided on an outer side of gas sealing members so as to penetrate each of the separators, and communication paths that detour around the gas sealing members in the thickness direction of the separators and connect the reaction gas communication ports with reaction gas flow passages. Furthermore, support members are provided to support the portions of the separators at which the gas sealing members and the cooling surface sealing member are disposed so as to be offset with respect to each other as viewed in the stacking direction.

摘要： A fuel cell stack includes a plurality of unit cells stacked in a stacking direction substantially along a direction of gravity. Each of the plurality of unit cells includes a first metal separator, a second metal separator, and a membrane electrode assembly sandwiched between the first metal separator and the second metal. A reactant gas channel allows a reactant gas to flow along a surface of each of the first and second metal separators. A reactant gas inlet manifold and a reactant gas outlet manifold allow the reactant gas to flow the reactant gas inlet manifold and the reactant gas outlet manifold in the stacking direction. A bridge portion forms a connection channel to connect at least the reactant gas outlet manifold to the reactant gas channel. The bridge portion includes a guide portion to break a continuity of condensed water.
