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: Disclosed is a pinhole inspection apparatus, system and method for a membrane electrode assembly of a fuel cell, which can easily detect the position of a pinhole using water and a pH test paper from discoloration caused when the water is in contact with the pH test paper through the pinhole, thus solving the existing problems and allowing the membrane electrode assembly to be reused after the inspection. In particular, a lower fixture is configured to support the membrane electrode assembly and water is uniformly distributed on an upper surface of the membrane electrode assembly. A pH test paper is inserted between the membrane electrode assembly and the lower fixture and discolored upon coming in contact with water that passes through a pinhole in the membrane electrode assembly, thus detecting the presence and position of the pinhole.
