Cell elements, each of which includes electrolyte plate such as fused carbonate, an anode plate and a cathode plate, and separator plates provided with heat transfer assisting means are piled up one after the other. Oxidizer gas supplied to one separator plate flows in the direction opposite to the oxidizer gas supplied to an adjacent separator plate, so that heat propagates easily in the direction the cell elements and the separator plates are piled up through the heat transfer assisting means, making the temperature profile of the fuel cell more gentle.

A fuel cell comprising: cell elements, each cell element including an electrolyte plate, an anode plate and a cathode plate, the electrolyte plate being sandwiched by the anode plate and he cathode plate; and separator plates, each separator plate possessing passages formed on the front and back faces thereof so as to supply fuel gas to the anode plate of a cell element and to supply gaseous oxidizer to the cathode plate of an adjacent cell element, the cell elements and the separator plates being piled up one after the other, creating plural stages, characterized in that said fuel cell further comprises: anode side gas supply means for supplying the fuel gas to fuel gas passages formed on one face of the separator plate; cathode side gas supplY means for supplying the gaseous oxidizer to the oxidizer passages formed on the other face of the separator plate in a manner such that the oxidizer gas supplied to one separator plate may flow in the direction opposite to the oxidizer gas supplied to adjacent separator; and heat transfer assisting means formed on the front and back faces of each separator plate so as to assist heat transfer in the direction the separator plates and the cell elements are piled up.
