Even when a reaction gas flows into a gap formed between a gasket and a membrane electrode assembly, the flowing of the reaction gas to the outside without flowing through an electrode is prevented and thus a decrease in power generation efficiency is prevented. In order to allow the water vapor contained in the reaction gas that flows into an anode-side gapformed between an anode-side gasketand a membrane electrode assemblyto condense in at least a part of the gap, and to allow the condensed water to fill the gap, the upstream portion of a cooling fluid channelof an anode-side separatoris formed such that it includes a region corresponding to the gap, and the upstream portion is formed such that it includes a region corresponding to a middle stream portion and subsequent portion of a fuel gas channel

Fuel cell and fuel cell stack comprising the same

The invention provides an MEA-gasket assembly () comprising: an MEA () having a polymer electrolyte membrane (A), catalyst layers and gas diffusing layers (C); a plate-like frame () which is joined to a portion of the polymer electrolyte membrane (A) so as to enclose the MEA (), the portion being located in a peripheral region of the MEA () and which has a plurality of fluid manifold holes (); and an annular gasket () formed on both faces of the frame (), wherein an annular gap formed between the inner peripheral edge of the annular gasket () and the outer peripheral edges of the gas diffusing layers (C) is at least partially closed.
