Abstract
To detect a moisture content in a power generation cell with accuracy and reduce a water storage amount in a fuel cell stack.SOLUTION: A fuel cell system (10) determines whether or not an anode gas and a cathode gas are in a dew condensation state on the basis of a humidity of the anode gas detected by a first humidity sensor provided in a power generation cell (22) and a humidity of the anode gas detected by a second humidity sensor provided in the power generation cell (22), and adjusts a water content of the gas that is determined to be in the dew condensation state.SELECTED DRAWING: Figure 1
