Abstract
In a fuel cell, a cathode passage extends from an oxidizing gas supply hole to an oxidizing gas discharge hole. A turn interval at which a flow direction of an oxidizing gas returns to an original direction in an upstream-side passage region is different from the turn interval in a downstream-side passage region. A ratio between the turn interval in the upstream-side passage region and the turn interval in the downstream-side passage region is set to 1.1:1 to 3:1. The upstream-side passage region is overlapped with a most downstream-side passage portion of an anode passage with a membrane electrode assembly interposed between the upstream-side passage region and the most downstream-side passage portion.
