PROBLEM TO BE SOLVED: To provide a wet state control device for a fuel cell for maintaining an electrolyte membrane in an appropriate wet state while suppressing deterioration of fuel economy.SOLUTION: The wet state control device includes preferential control units (B101 and B201) which control either one of a pressure or flow rate of cathode gas preferentially when adjusting the wet state of the fuel cell (10); water temperature control units (B102 and B202) which control a temperature of cooling water when control of the preferential control units (B101 and B201) does not satisfactorily control the wet state of the fuel cell; and compensation control units (B103 and B203) that control the other of the pressure and flow rate of the cathode gas so as to compensate response delay of the water temperature control units. |
