PROBLEM TO BE SOLVED: To provide technology, capable of easily controlling moisture content in reaction gas to be supplied to a fuel cell. SOLUTION: A fuel cell system is equipped with a fuel cell 100; a reactant gas passage 352 for passing the reactant gas to be supplied to the fuel cell; and an off-gas passage 354 for passing the off-gas exhausted from the fuel cell. A moisture absorbing-desorbing part 320 is installed midway of the reaction gas passage 352 and midway of the off-gas passage 354, and the moisture absorbing-desorbing part 320 contains a rotating member, which absorbs moisture in the off-gas and discharges the moisture to the reactant gas. The number of revolutions of the rotating member is controlled by a control part. |
