    摘要： Even if reaction gas flows into a substantially rectangular anode-side and cathode-side gaps formed between an annular main body portion and a membrane electrode assembly in an anode side and a cathode side of a fuel cell, the reaction gas is prevented from flowing out from an outlet without passing through an electrode to cause degradation of power generation efficiency. At least one of anode-side gasket and cathode-side gasket in the fuel cell is provided with an extra sealing portion connected to an annular main body portion in such a manner that, among two pairs of gap portions opposing to each other in the anode-side gap and the cathode-side gap, the extra sealing portion intersects with one pair of gap portions having a larger pressure gradient of fuel gas and oxidant gas in a direction from an upstream side to a downstream side of a fuel gas flow channel and an oxidant gas flow channel.
