PROBLEM TO BE SOLVED: To provide a fuel cell system capable of collecting a cross-leaking liquid of a fuel cell to a fuel supply path.SOLUTION: When a liquid in a gas-liquid separator 82 is collected in a gas-liquid separator 24, a circulating current solenoid valve 102 is closed and an air back pressure regulation valve 105 is made a certain amount larger in opening. Consequently, pressure in the gas-liquid separator 82 rises. After the pressure in the gas-liquid separator 82 has risen, the pressure difference Pbetween the air pressure P2' in the gas-liquid separator 82 and pressure in the gas-liquid separator 24 is calculated. A flow rate Qcorresponding to the pressure difference Pbetween the air pressure P2' in the gas-liquid separator 82 and the pressure in the gas-liquid separator 24 is acquired. When the pressure in the gas-liquid separator 82 is rising, the amount of a liquid reserved in the gas-liquid separator 82 is acquired. Then the amount of the liquid is divided by the flow rate Qto calculate a time for which the circulating current solenoid valve 102 should be opened. |
