Zusammenfassung:	PROBLEM TO BE SOLVED: To finely suppress the residence or drift of reaction gas at a boundary part between a reaction gas channel and a buffer portion, and to uniformly and smoothly supply the reaction gas to the whole of the reaction gas channel.SOLUTION: On a first separator 14 configuring a fuel cell, an oxidant gas channel 26 for supplying oxidant gas along an electrode surface; and an oxidant gas inlet communication hole 20a for introducing the oxidant gas to the oxidant gas channel 26 are formed. On the other hand, on a resin frame member 42 configuring an outer peripheral portion of an electrolyte membrane/electrode structure, an inlet side resin projecting portion 44a configuring an inlet guide channel 46a for coupling the oxidant gas inlet communication hole 20a and the oxidant gas channel 26 is formed. A projecting end portion 26tf of a projecting portion 26a configuring the oxidant gas channel 26 and a recessed end portion 44at of the inlet side resin projecting portion 44a configure a fitting part 48a at which the end portions are fitted with each other.
