PROBLEM TO BE SOLVED: To provide a fuel cell that easily and reliably drains produced water that is likely to be accumulated in a lower portion of a reactant gas passage in a direction of gravitational force, from the reactant gas passage with a simple configuration.SOLUTION: A fuel cell 10 includes a membrane electrode assembly 12, a first separator 14, and a second separator 16. In the second separator 16, a fuel gas passage 32 is provided in communication with a fuel gas inlet communication hole 24a and a fuel gas outlet communication hole 24b. The fuel gas passage 32 includes: a plurality of wavy passages 32a that each extend in a horizontal direction and that are arranged in the direction of gravitational force; and a flat passage 32b that is arranged in a power generation region and at the bottom in the direction of gravitational force and that extends in a horizontal direction. |
