Abstract
A control device of a fuel cell system sets a required output of a fuel cell stack that is required according to a present power demand and predicts the required output and the current according to the temperature of the fuel cell stack from a predetermined output state map that is preset. The control device sets an operation state quantity according to the predicted current and the temperature of the fuel cell stack from a predetermined operation state quantity map that is preset. The control device includes at least one of a pressure at an air supply port of air that is supplied to the cathode electrode of the fuel cell stack, a utilization rate of the air at the cathode electrode, a flow rate of a cooling medium that cools the fuel cell stack, and humidity of the air at the air supply port as the operation state quantity.
