Abstract
A fuel cell () includes a stacked body of a membrane electrode assembly () and of separators (). Then, the membrane electrode assembly () and the separators () are formed into a substantially rectangular shape, the separators () include flow passages. Moreover, an aspect ratio R as a ratio (flow passage length/flow passage width) of a flow passage length with respect to a flow passage width is 0.01 or more to less than 2. Furthermore, a horizontal direction equivalent diameter D (mm) of the flow passages satisfies Expression ():×(×Acat)  Expression (1)
