PURPOSE: An air blower for a fuel cell vehicle is provided to improve durability by reducing an axial load of the air blower as a decompression passage is connected from the rear side to the front side of an impeller along a rotary shaft of a motor to make air of high pressure in the rear side of the impeller flow to the front side of the impeller. CONSTITUTION: An air blower(100) for a fuel cell vehicle comprises an inlet duct(200), a motor housing unit(300), an impeller housing unit(400), an impeller(410), and a support member(500). The inlet duct includes an air inlet(210) where external air flows in. The motor housing unit is joined to a rear end of the inlet duct, and a motor(310) is installed in inside. The impeller housing unit is joined to a rear end of the motor housing unit, and an air outlet(440) is formed in one side of the impeller housing unit. The impeller is installed inside the impeller housing unit, thereby compressing air while being rotated by the motor. The support member is joined to a rear end of the impeller housing unit, thereby supporting a rotary shaft(320) of the motor to be rotatable. A compression passage(900) is formed inside the rotary shaft of the motor.
