PURPOSE: An apparatus for controlling air supply of a fuel system is provided to reduce a back pressure applied to the rear part of an air blower when high flux is needed and to easily increase air supply flux using the air blower. CONSTITUTION: An apparatus for controlling air supply of a fuel system comprises: an air blower(16) supplying external air; a humidifier(20) supplying the external air to an air electrode(14) of a fuel cell stack(10) by humidifying the external air from the air blower; and an air exhaust line(40) which is connected to an exit of the air electrode and the humidifier. A bypass line(50) is connected to a random location of the air exhaust line and a mechanical bypass valve(52) is mounted on the bypass line. |
