Zusammenfassung:	PURPOSE:To improve heat recovery from a heat exchanger to effectively utilize exhaust heat in a cooling system by constituting each heat exchanger installed between cell stacks with two heat exchange elements having different functions. CONSTITUTION:In a pair of heat exchange elements between cell stacks S1-S4, the first cooling medium (A-A') flowing through the first elements H11, H21, H31, and H41 is different from the second cooling medium (B-B') flowing through the second elements H12, H22, H32, and H42, and each cooling medium is distributed in parallel. The inlet temperature of each cell stack is about 135 deg.C and the outlet temperature is about 180 deg.C, and the temperature difference of 55 deg.C is heat-exchanged by cooling gas flowing in circulation path while it passes the heat exchange elements Hn1, Hn2 installed between stacks. Thereby, heat recovery from the heat exchangers installed between cell stacks is improved and exhaust heat in the cooling system is effectively utilized.
