  "textContent": "A fuel cell (1) of the present invention includes a stacked body of a membrane electrode assembly (3) including anode and cathode electrode layers on both surfaces of an electrolyte membrane (7) and of separators (2). Then, the membrane electrode assembly (3) and the separators (2) are formed into a substantially rectangular shape, the separators (2) are smooth or include flow passages, and each of the electrode layers includes a gas diffusion layer and a catalyst layer. 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 on a cathode side or anode side of the membrane electrode assembly (3) is 0.01 or more to less than 2. Furthermore, a horizontal direction equivalent diameter D (mm) of the gas diffusion layer or the flow passages satisfies Expression (1): D = B × R × Acat 1 / 3 (where Acat is a catalyst area (cm 2 ) of the membrane electrode assembly (3), and B is a constant of 0.005 or more to 0.2 or less).",
