<P>PROBLEM TO BE SOLVED: To provide a fuel cell system capable of combining a measure against carbon oxidization in a fuel cell with the adjustment of the humidification amount of gas supplied to the fuel cell. <P>SOLUTION: The fuel cell system is equipped with a fuel cell 10 generating power by electrochemical reaction of reaction gasses; a gas supply passage 20 supplying reaction gas to the fuel cell; a humidifier 24 installed in the gas supply passage; a bypass passage 30 supplying the reaction gas to the fuel cell by bypassing the humidifier; an opening variable valve 31 controlling the flow state of the reaction gas in the bypass passage; an on-off valve 32; and a control part 50, and the control part 50 switches over a first state shutting off the passage of the bypass passage and a second state securing the passage of the bypass passage, and adjusts the humidification amount of the reaction gas supplied to the fuel cell by controlling the flow rate of the reaction gas flowing through the bypass passage in the second state. <P>COPYRIGHT: (C)2009,JPO&INPIT |
