<P>PROBLEM TO BE SOLVED: To provide a fuel cell system capable of achieving miniaturization and stabilizing an operation, and to provide its design method. <P>SOLUTION: The fuel cell system 1 includes: a reformer for creating a reformed gas by reforming a raw fuel; a fuel cell 3 for generating electric power by using the reformed gas and air; humidifiers 7, 9 for humidifying at least one of the reformed gas and air supplied to the fuel cell 3; a water processing system 30 including a water pump 41 and an ion exchanger 14 and circulating and supplying water to the ion exchanger 14 with the water pump 41; flow passages H9, H11 connected upstream of the ion exchanger 14 but downstream of the water pump 41 and connecting between the humidifiers 7, 9 and the water processing system 30; and solenoid valves 44, 46 respectively arranged on the flow passages. When the water is supplied to the humidifiers 7, 9, output of the water pump 41 is raised while the solenoid valves 44, 46 are opened. <P>COPYRIGHT: (C)2011,JPO&INPIT |
