The present invention relates to an offset correction method of inverter hall sensors for an air blower of a fuel cell vehicle, to measure and correct the offset angle of the hall sensors before controlling current of a permanent magnet synchronous motor (PMSM). According to an embodiment of the present invention, the offset correction method of inverter hall sensors for an air blower of a fuel cell vehicle comprises the following steps of: an inertial braking step to block current applied to a permanent magnet synchronous motor (PMSM) driving a blower used for an air supply system of a fuel cell; a step of calculating an angle to calculate an offset angle by measuring Vd_syn and Vq_syn in the inertial braking step; and a step of correcting an angle of the hall sensor based on the calculated angle of a synchronous coordinates.
