In a fuel cell comprising: cell elements (10), including each an electrolyte plate, an anode plate and a cathode plate, the electrolyte plate being sandwitched by the anode plate and the cathode plate; and separator plates (18) possessing each passages (A1, A2, C1, C2) formed on the front and back faces thereof so as to supply fuel gas to the anode plate of the cell element (10) and to supply gaseous oxidizer to the cathode plate, the cell elements (10) and the separator plates (18) being piled up one after the other, creating plural stages, anode side gas supply means (30a, 32a) for supplying the fuel gas to fuel gas passages (A1, A2) formed on one face of the separator plate (18); cathode side gas supply means (34a, 36a) for supplying the gaseous oxidizer to the oxidizer passages (C1, C2) formed on the other face of the separator plate (18) in a manner such that the oxidizer gas supplied to one separator plate (18) may flow in the direction opposite to the oxidizer gas supplied to adjacent separator plates (18); and heat transfer assisting means (22, 24) formed on the front and back faces of each separator plate (18) so as to assist heat transfer in the direction the separator plates (18) and the cell elements (10) are piled up. |
