Abstract
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
