AIR SUPPLY SYSTEM FOR FUEL CELLS AND METHOD FOR CONTROLLING THE SAME

An air supply system for fuel cells includes a fuel cell, an air supply line connected to a cathode of the fuel cells to supply external air to the cathode of the fuel cell, an air pressure sensor provided on the air supply line, and configured to measure a pressure in the air supply line, a determiner configured to determine whether correction for the air pressure is necessary, and a controller connected to the determiner and configured to perform the correction for the air pressure sensor by performing voltage control of the fuel cell, upon determining that the correction for the air pressure sensor is necessary.
