PURPOSE: To provide a fuel cell which can improve a cell output. CONSTITUTION: A fuel cell 1 is provided with a fuel electrode 4 having a fuel reaction layer 41 and a fuel diffusion layer 42, an oxygen electrode 5 having an oxygen reaction layer 51 and an oxygen diffusion layer 52, an electrolyte layer 3 which is set between the fuel electrode 4 and the oxygen electrode 5, a cell frame 7 of the fuel electrode side contacting the fuel electrode 4 and a cell frame 8 of the oxygen electrode side contacting the oxygen electrode 5. The fuel diffusion layer 42 is provided with a fuel diffusion layer core 421, an outside fuel electrode water repellent layer 422 having and an inside fuel electrode water repellent layer 423. The oxygen diffusion layer 52 is provided with an oxygen diffusion layer core 521, an outside oxygen electrode water repellent layer 522 and an inside oxygen electrode water repellent layer 523. In the fuel cell 1, water repellency of the inside fuel electrode water repellent layer 423 and the outside fuel electrode water repellent layer 422, is higher than that of the inside oxygen electrode water repellent layer 523 and the outside oxygen electrode water repellent layer 522. |
