PROBLEM TO BE SOLVED: To provide a fuel cell system which efficiently generates water used in a reformer.SOLUTION: A fuel cell system 1 comprises: a fuel cell 11; an off-gas line L9 which is connected to the fuel cell 11 and connected to an exhaust line L11 at a line connection part 40, and through which off-gas G5 exhausted from the fuel cell 11 circulates to the exhaust line L11; a dehumidifying rotor 17 which is provided so as to straddle the exhaust line L11 and an intake line L13 and in a downstream side in the exhaust line L11 from the line connection part 40, and into which adsorbent for adsorbing moisture is charged; and a heat exchanger 15 which is provided in a downstream side in the exhaust line L11 from a dehumidifying rotor 17 and heats air A1 circulating in an air supply line L7 by exchanging heat between inner air A2 passing through the dehumidifying rotor 17 and the air A1 circulating in the air supply line L7. |
