PURPOSE:To reduce the corrosion at the outer periphery end sections of separators and the inner end sections of manifolds due to the leakage of an electrolyte and extend the cell life by pinching a dry seal between the separators to surround an electrolyte plate. CONSTITUTION:A fuel cell is constituted of multiple cells 4 each consisting of two parallel electrodes, an anode 2 and a cathode 3, and a flat electrolyte plate (tile) 1 pinched between the electrodes and separators 10 pinched between the cells 4. A dry seal 20 such as a ceramic packing is pinched between the surfaces of adjacent separators 10 to surround the tile 1. Even if an electrolyte is leaked from the tile 1, the further leakage is blocked by the dry seal 20, and the corrosion at the outer periphery end sections of the separators 10 can be reduced. |
