Abstract
A fuel cell system includes a fuel cell for generating electrical power upon being supplied with anode gas and cathode gas. The fuel cell system includes a wetness control state determination unit that determines whether or not a wetness control of controlling a degree of wetness of an electrolyte membrane of the fuel cell is normally executed, a combined capacitance calculation unit that calculates a combined capacitance of the fuel cell, and an anode gas concentration control unit that determines the occurrence of decrease in an anode gas concentration in the fuel cell or executes a control for increasing the anode gas concentration if the combined capacitance of the fuel cell is smaller than a predetermined value when the wetness control is determined to be normally executed.
