GAS SEPARATOR FOR A FUEL CELL, AND FUEL CELL USING THE SAME GAS SEPARATOR FOR A FUEL CELL

摘要

A fuel cell enhancing the utility rate of supplied gas includes a separator having a plurality of holes extending therethrough and a plurality of ribs communicating between mutually confronting holes. Oxidizing gas supplied into the fuel cell passes through a first oxidizing gas feed manifold formed by a first hole, 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 formed by a second hole. This oxidizing gas is guided into a return plate 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.
