PROBLEM TO BE SOLVED: To provide a fuel cell that reliably drains produced water from an outlet of a reactant gas flow path into a reactant gas outlet communication hole and that favorably reduces pressure drop.SOLUTION: A fuel cell includes cell units 12 each having a first separator 14. In a surface 14a of the first separator 14, a first fuel gas flow passage 36 is formed. An inlet and an outlet of the first fuel gas flow passage 36 communicate with an inlet buffer section 38 and an outlet buffer section 40, respectively. The outlet buffer section 40 has a plurality of guide flow passages 42a to 42g. The guide flow passage 42a has: a straight portion 43a that is positioned near the outlet of the first fuel gas flow passage 36; and a curved portion 43b that is positioned near a fuel gas outlet communication hole 32b, that communicates integrally with an end of the straight portion 43a, and that is curved toward the fuel gas outlet communication hole 32b. |
