For a fuel cell system, the flow rate and the pressure of the air flow supplied to the cathode side are controlled with the following procedure. First, air is supplied to the cathode at the flow rate and supply pressure required for generating electricity. In this state, the changing rate of the amount of formed water accumulated in the cathode is estimated based on the required electricity generation and the air flow rate. When the accumulated amount of formed water increases in a high rate, to avoid flooding, the cathode outlet regulation valve is intermittently opened to decrease the outlet gas pressure. Also, at a frequency less than that of the pressure decrease, the air flow rate is increased. By executing this operation, the increased air flow rate and the pressure difference between the cathode inlet and outlet, it is possible to promote discharge of the formed water with small loss of energy.
