Abstract: A fuel cell system and a control method thereof are provided. In the system, an oxygen sensor is mounted on the anode inlet side and the anode outlet side of a fuel cell stack to measure an oxygen concentration. Based on the measured oxygen concentration, a control operation is performed on the fuel cell system to reduce the oxygen concentration on the anode side. Accordingly, the irreversible deterioration of the fuel cell occurring due to the reverse voltage of the cell during driving of the fuel cell vehicle and the cathode carbon corrosion occurring due to the inflow of air during parking are effectively reduced, thereby increasing the durability of the fuel cell and the fuel cell vehicle.

Abstract: A fuel cell system includes a fuel cell stack including an air electrode and a fuel electrode, a stack housing having a hollow therein to accommodate the fuel cell stack in the hollow, an air compressor configured to pump air to supply the air to the air electrode, a ventilation pipe connecting an entrance of the air compressor and the hollow, and at least one vent hole provided on an outer wall of the stack housing such that the hollow and an outside of the stack housing communicate with each other. An interior of the stack housing is ventilated by lowering of a pressure at the entrance of the air compressor, which is generated as the air compressor is operated, while air outside the stack housing is suctioned into the entrance of the air compressor after passing through the vent hole, the hollow, and the ventilation pipe.
