Abstract:
A fuel cell system (10) that includes with a polymer electrolyte fuel cell (22) having a polymer electrolyte membrane is provided with a determining portion that determines whether a moisture content in the polymer electrolyte membrane is low, and an anode gas pressure regulating portion that sets a gas pressure on an anode side of the fuel cell lower than a set value of the gas pressure on the anode side during steady operation in which the moisture content is not low, when it is determined that the moisture content is low.
