Abstract
When the fuel cell stack is operated in a state in which the air stoichiometric ratio is smaller than the predetermined value, the controller calculates the amount of retained water that has been retained in the cathode flow path of the fuel battery cell per fixed time in such a way that the calculated amount includes an extra amount therein, integrates the amount of retained water per fixed time that has been calculated in such a way that the calculated amount includes the extra amount therein, and executes air blow in the cathode flow path of the fuel battery cell when the integrated value of the amount of retained water becomes equal to or larger than the threshold.
