摘要： A fuel cell includes a membrane-electrode assembly and a separator. The membrane-electrode assembly has an electrolyte and a pair of electrodes that are disposed on respective sides of the electrolyte. The membrane-electrode assembly and the separator are stacked in a stacking direction. A reaction surface of the membrane-electrode assembly is in a vertical direction along a direction of gravity and has a shape having a longer dimension in a horizontal direction. The fuel cell is provided with a reactant gas passage to allow a reactant gas to flow along a longitudinal direction of the reaction surface. The reactant gas is an oxidant gas or a fuel gas. A drain channel to allow product water from the reactant gas passage to be drained away is disposed between the membrane-electrode assembly and the separator and under the reaction surface in the direction of gravity.

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 power generation cell includes a membrane electrode assembly, with an anode side metal separator and a cathode side metal separator sandwiching the membrane electrode assembly. Flow field walls are provided within the coolant flow field for preventing coolant from flowing into an area corresponding to an oxygen-containing gas inlet buffer, while allowing the coolant to flow into an area corresponding to an oxygen-containing gas outlet buffer. Likewise, flow field walls contact each other for preventing the coolant from flowing into an area corresponding to a fuel gas inlet buffer, while allowing the fuel gas to flow into an area corresponding to a fuel gas outlet buffer.
