PROBLEM TO BE SOLVED: To provide a driving method of a fuel cell power generating device which prevents original fuel system, air system, and electric system of a fuel cell from temporary disturbance in the case of INV re-try at system irregularity, and aims to prevent the deterioration of the fuel cell. SOLUTION: At the system interconnection operation of the fuel cell, in the case of system irregularity, when standby operation of the fuel cell is carried out until system irregularity recovers, by instantaneously stopping an inverter, and restarting after prescribed period (T1), the system irregularity is detected at a system irregularity detecting part 31, and control indication value at an indicated/ measured value switching indication part 33 of INV re-try treatment part 32, such as current, voltage, flowing volume of original fuel, flowing volume of air, and a control indication value of fuel gas and oxidant gas at the supply system such as an original fuel valve and an air system blower, are switched from the existing value to the estimated value for the time of standby (time of re-try) at a switching part 36, and standby operation is continued after operating the fuel cell for a prescribed period (T2). |
