PURPOSE:To make construction simple by constructing the portion, facing a manifold for cooling air, of a manifold for reaction air with a heat resistant, insulating, elastic plate having a seal frame in which each cooling plate projection part is fixed in airtightness, and arranging a supporting plate having a window with a play of each seal frame on the elastic plate. CONSTITUTION:A cell stack 1 is assembled in such a way that a unit cell is constructed by interposing electrolyte matrix between gas electrodes, and a gas separating carbon plate is prepared by arranging reaction gas (hydrogen and air) flow path in the direction crossing each other on its both sides, then a large number of unit cells and gas separating plates are stacked, and carbon cooling plates 2 having air flow path 5 are placed every four to five unit cells, then they are tightened after the upper and lower end plates are placed. Each cooling plate 2 is projected from the air flow surface of the stack 1 and connected to a cooling air manifold 6. A reaction air manifold 3 is constructed with a frame 31 and a plate 32, and a window 4 in which a cooling plate projecting part 2' is fixed with a play is installed at certain spaces in the plate 32. A sealing frame 12 in which the cooling plate projection part 2' is fixed in airtightness is installed in a heat resistant, insulating, elastic plate 11 such as fluorine rubber formed in the plate 32. |
