<P>PROBLEM TO BE SOLVED: To provide a fuel cell system capable of effectively utilizing waste heat from a solid electrolyte fuel cell, capable of reducing temperature at a wall face of the fuel cell to safe temperature. <P>SOLUTION: The fuel cell system is provided with a solid electrolyte fuel cell having wall face, a hot water tank storing hot water, a first heat exchanger, a second heat exchanger mounted on the wall face of the solid electrolyte fuel cell, a water circulation piping successively connecting a bottom part of the hot water tank, the first heat exchanger, the second heat exchanger, and an upper part of the hot water tank, and a waste gas piping connecting the solid electrolyte fuel cell and the first heat exchanger. Waste gas flowing out of the solid electrolyte fuel cell is exhausted through the first heat exchanger. Heat exchange is performed between the waste gas and water by the passage of the water flowing out of the hot water tank through the first heat exchanger, and also heat exchange is performed between the wall face of the solid electrolyte fuel battery and water by the passage of the water passing through the first heat exchanger through the second heat exchanger. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
