PURPOSE:To prevent the protrusion of a seal, the discrepancy between the seal and an electrode and the making of a gap on a conjoined portion, by providing recesses in the portion of a gas separation plate, which is in contact with a gas sealing section made of the seal. CONSTITUTION:Recesses 10 are provided in the portion of a gas separation plate 1, which is in contact with a gas sealing section made of a seal 7. For example, dimples are provided as the recesses 10. Each of the dimples is 3mm in diameter and 1.5mm in depth. The dimples are located at intervals of several millimeters. The unnecessary projections of the seal 7 are located in the recesses 10 to prevent the outward protrusion of the seal and firmly fix the seal in position to keep the seal from deviating. |
