Abstract
A fuel cell is provided with a separator that supports an electrolyte/electrode assembly sandwiched therebetween. The separator is provided with: first and second fuel gas supply parts in the center of which fuel gas supply holes are formed; first and second cross-link parts connected to the first and second fuel gas supply parts; and first and second sandwiching support parts connected to the first and second cross-link parts. Each first sandwiching support part is provided with a set of fuel gas exhaust passages that discharge fuel gas that has gone through a fuel gas passage and been used. The cross-sectional areas of the fuel gas exhaust passages are larger on the downstream sides than on the upstream sides, in terms of the direction of fuel gas flow.
