Abstract
A wet state control device for fuel cell includes a priority control unit for preferentially controlling either one of a pressure and a flow rate of cathode gas when a wet state of a fuel cell is adjusted, a water temperature control unit for controlling a temperature of cooling water when the wet state of the fuel cell is not completely adjustable by a control of the priority control unit, and a complementary control unit for controlling the other of the pressure and the flow rate of the cathode gas to complement a response delay of the water temperature control unit.
