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.
