It is an object of the invention to improve the accuracy of estimating a moisture content and suppress an effect of remaining water at the startup of the fuel cell system. A fuel cell system includes: a fuel cell including a cell laminate; an estimating unit for estimating a residual water content distribution in the reactant gas flow channel and a moisture content distribution in the electrolyte membrane in a cell plane of each single cell while taking into consideration water transfer that occurs between the anode electrode and the cathode electrode via the electrolyte membrane; and an operation control unit for, based on an estimation result from the estimating unit, setting a scavenging time used in a scavenging process for the fuel cell after the fuel cell system is shut down. |
