A fuel cell where sealing can be reliably made for each unit cell. The structure enables to thin the fuel cell and facilitates maintenance. The fuel cell is small in size and light in weight and enables free shape design. The fuel cell has a plate- like solid polymer electrolyte (1) and a pair of electrode plates (2, 3) on both sides of the solid polymer electrolyte (1). The fuel cell further has a pair of metallic plates (4, 5) arranged on both sides of the electrode plates (2, 3). Flow path grooves (9), and inlet openings (4c, 5c) and discharge openings, communicating with the flow path grooves (9), are provided in the metallic plates (4, 5). The peripheral edges of the metallic plates (4, 5) are mechanically sealed with an insulation material (6) interposed between the metallic plates. |
