<P>PROBLEM TO BE SOLVED: To miniaturize a fuel cell system and reduce its cost while enhancing stability of humidification control, accuracy, and response without causing deterioration of thermal efficiency of the entire system. <P>SOLUTION: This fuel cell system is equipped with a humidifier 14 to supply an oxidizer gas to an oxidizer electrode by humidifying it. The humidifier 14 is provided on a condensed coolant circulating circuit 75 for a liquid heating medium which has at least collected exhaust heat exhausted from a fuel cell 10 and/or exhaust heat generated in a reformer 20 to circulate, and the heating medium is vaporized by utilizing collected heat to humidify the oxidizer gas. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
