A fuel cell enhancing the utility rate of supplied gas includes a separator (30) having a plurality of holes (40, 41, 42, 43, 44, 45) extending therethrough and a plurality of ribs (55, 56, 57)communicating between mutually confronting holes. Oxidizing gas supplied into the fuel cell passes through a first oxidizing gas feed manifold (60, 61, 62)formed by a first hole (40, 42, 44), is distributed into a first unit cell inside oxidizing gas passage formed by a first rib, and is merged in an oxidizing gas exhaust manifold (63, 64, 65) formed by a second hole (41, 43, 45). This oxidizing gas is guided into a return plate (70) disposed at the end of the fuel cell, is further led into a second oxidizing gas feed manifold, and is distributed into a second unit cell inside gas passage. The oxidizing gas sequentially passes through plural unit cell inside oxidizing gas passages. <IMAGE> |
