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.

摘要： A first metal separator of one of adjacent power generation cells and a second metal separator of the other of the adjacent power generation cells are directly stacked together to form a coolant flow field. The first metal separator has a press line protruding toward the coolant flow field, between a fuel gas flow field and an inlet buffer. The second metal separator has a press line protruding toward the coolant flow field, between an oxygen-containing gas flow field and an inlet buffer. The press lines contact each other to limit flow of the coolant into a back surface buffer.
