<P>PROBLEM TO BE SOLVED: To provide a fuel cell system preventing oxidation deterioration of an anode of a fuel cell stack. <P>SOLUTION: In the fuel cell system 1 having a reformer 2 producing reformed gas by reforming reforming raw material; and an SOFC stack 3 connected to the reformer 2 through a reformed gas supply pipe 10 and generating power with reformed gas obtained with the reformer 2 and air, a coolant circulation member 4 for circulating water as a coolant is installed between the reformer 2 and the SOFC stack 3, a heat exchanger 13 for cooling gas in the reformed gas supply pipe 10 is installed in the reformed gas supply pipe 10, and water is supplied to the heat exchanger 13. Water passed through the heat exchanger 13 is circulated to the coolant circulation member 4, and heat (radiation heat) generating in the reformer 2 is absorbed in water in the coolant circulation member 4. <P>COPYRIGHT: (C)2008,JPO&INPIT |
