A humidifier for fuel cell vehicles is provided to increase the heat and material transfer rate between dry gas flown inside a hollow fiber membrane and humid gas by forming the humid gas flown the outside of the hollow fiber membrane according to the rotation of a bundle of the hollow fiber membrane. A humidifier for fuel cell vehicles comprises a cylindrical housing(10) equipped with the first outlet(12) and the first inlet(11) at the one side of the upper part and the lower part; a circular plate(13) combined at both sides of the housing to be rotatable; many hollow fiber membranes(20) of which both ends are fixed to a disk and which flows dry gas into the inside; and a third outlet which generates the torque while ejecting the dry air, and is formed in a cylindrical direction of the hollow fiber membranes arranged at the outside of disk. |
