<P>PROBLEM TO BE SOLVED: To obtain a management method in which the quality of recovered water is maintained at a prescribed level even if operated for a long time in a fuel cell generator in which reaction-generated water of a fuel cell stack 1 and combustion-generated water of a reformer 2 are recovered in a recovery tank 3, and in which the water is used as cooling water of the fuel cell stack 1 and steam for reforming of the reformer 2. <P>SOLUTION: An electric conductivity of the recovered water is measured by an electric conductivity measuring sensor 21 installed at the recovery tank 3, its detected signal is sent to a controller 22, and when the measured value exceeds a specified value, a part of the recovered water is discharged by opening a flow rate adjusting valve 23, and simultaneously, pure water of the same amount as that of discharged water is supplied from a pure water supply means 6 to the recovery tank 3 by opening the flow rate adjusting valve 24. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
