A fuel cell (10) is provided with a separator (28) that supports an electrolyte/electrode assembly (26) sandwiched therebetween. The separator (28) is provided with: first and second fuel gas supply parts (32, 52) in the center of which fuel gas supply holes (30) are formed; first and second cross-link parts (34, 54) connected to the first and second fuel gas supply parts (32, 52); and first and second sandwiching support parts (36, 58) connected to the first and second cross-link parts (34, 54). Each first sandwiching support part (36) is provided with a set of fuel gas exhaust passages (42a, 42b, and 42c) that discharge fuel gas that has gone through a fuel gas passage (40) and been used. The cross-sectional areas of the fuel gas exhaust passages (42a, 42b, and 42c) are larger on the downstream sides than on the upstream sides, in terms of the direction of fuel gas flow. |
