APPARATUS AND METHOD FOR CORRECTING OFFSET OF PRESSURE SENSOR IN FUEL CELL SYSTEM

Introduced are an apparatus for correcting an offset of a pressure sensor in a fuel cell system including a first pressure sensor and a second pressure sensor, which are installed between a rear end of a fuel supply valve of a hydrogen supply system and an anode inlet, and a method of correcting an offset using the same. The apparatus includes an offset corrector that calculates offsets between the sensors from a condition of same pressure of each of the sensors and corrects offsets with respect to the first pressure sensor and the second pressure sensor using the calculated offsets.
