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.

The fuel cell (10) includes a membrane electrode assembly (14) and first and second metal separators (16, 18) sandwiching the membrane electrode assembly (14). Connection channels (28a, 28b) are provided on the first metal separator (16). The connection channels (28a, 28b) connect the oxygen-containing gas supply passage (20a) and the oxygen-containing gas discharge passage (20b) to the oxygen-containing gas flow field (26). The membrane electrode assembly (14) has first overlapping portions (66a, 66b) overlapped on the connection channels (28a, 28b) for sealing the connection channels (28a, 28b). The first overlapping portions (66a, 66b) comprise, in effect, a gas diffusion layer.

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.
