<P>PROBLEM TO BE SOLVED: To provide a water feeder of a fuel cell power generation system, capable of maintaining a water treatment device during operation without causing lowering of a life of an ion exchange resin even if the volume of feeding water is reduced. <P>SOLUTION: Water of high purity produced in the water treatment device is once stored in a water tank by disposing the water treatment device 33 on the upstream side of the water tank 32, and the water stored in the water tank is fed to each part of the fuel cell power generation system by water supply pumps 34, 35. The water tank is divided into first, second and third tanks 41, 42, 43. Or, it is separated to a first water tank and a second water tank. In addition, a quantity and purity of water in the water tank are secured by controlling a solenoid valve 50, the circulation pump 37 serving as a water circulating means and the like, based on a detected signal of a level sensor 47 and a conductivity sensors 51, 52. <P>COPYRIGHT: (C)2004,JPO |
