<P>PROBLEM TO BE SOLVED: To improve the system efficiency of a fuel cell power generating apparatus by restraining the lowering of the temperature of a cell-cooling water by preferentially utilizing recovered water as reforming water when supplying water from a recovered water tank to a cell cooling water system tank. <P>SOLUTION: The cell cooling water system tank 55a disposed on a cooling water circulation circuit of the fuel cell 1 is divided into a reforming water tank 55b and a cell-cooling water tank 55c. At the same time, a communication part 55d, through which the water in divided tanks is made to communicate, is formed at least at a part of the respective divided tanks. Water is guided from a recovered water tank 31 to the reforming water tank 55b, and the reforming water for a reforming device 3 is made to be guided from the reforming water tank 55b. Further, the cooling water for the fuel cell 1 is made to reflow into the cell-cooling water tank 55c after being guided out from the cell-cooling water tank 55c and flowing through the fuel cell. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
