PROBLEM TO BE SOLVED: To prevent both pressure loss of gas and flooding on the gas supply side.SOLUTION: A fuel battery cell 100 forms, as an expand passage, an oxidation gas cathode passage from an oxidation gas supply hole 104IN to an oxidation gas exhaust hole 104OT. A turn interval T required for the direction of flow of oxidation gas to return to an original direction is set wider than a turn interval Td in which a turn interval Tu in an upstream passage area Ru is located in a downstream passage area Rd (Tu:Td=1.1: 1 to 3:1). In addition to this, the upstream passage area Ru is superposed on the furthest downstream passage Srd of the fuel gas passage 200 in the shape of a serpentine passage in an anode-side separator 120, with MEGA 110 interposed between them.SELECTED DRAWING: Figure 7 |
