<P>PROBLEM TO BE SOLVED: To suppress drop in circulation amount in an anode circulation passage and to realize power generation, according to the required load. <P>SOLUTION: A fuel cell system, arranging a humidifier 80 humidifying anode supply gas for supplying to a fuel cell 20 with anode offgas exhausted from the fuel cell 20 in the anode circulation passage for resupplying the anode offgas to the fuel cell 20 and circulating it, is equipped with a bypass passage 81, through which the anode offgas bypasses the humidifier 80. An opening adjusting valve 82 is installed in the bypass passage 81 as a bypass flow rate control means for controlling the flow rate of the bypass passage 81 according to the required load with respect to the fuel cell 20. <P>COPYRIGHT: (C)2007,JPO&INPIT |
