Abstract: The present invention relates to a fuel cell membrane humidifier which can prevent gas leakage due to repetition of driving and stopping of a fuel cell, can be manufactured with relatively low manufacturing costs and high productivity, and can suppress vibrations generated during operation. A fuel cell membrane humidifier according to an embodiment of the present invention comprises: a humidification module for humidifying air supplied from the outside with moisture in exhaust gas discharged from a fuel cell stack; and caps respectively coupled to both ends of the humidification module. The humidification module comprises: a mid-case which has both ends opened and a step difference formed on the inner circumferential surface thereof; at least one cartridge which is disposed within the mid-case and accommodates a plurality of hollow fiber membranes; a fixed layer in which ends of the hollow fiber membranes are potted and supported by the inner wall of the mid-case; a bracket which is supported by the step difference of the mid-case and is in contact with the fixed layer; and a packing member which has a groove into which an end of the mid-case is fitted and is in contact with the bracket. In addition, the humidification module has a damping protrusion which is formed on the inner wall of the mid-case and fitted into the fixed layer to suppress vibration generated in the cartridge by air flowing inside the humidification module.

Abstract: The present invention relates to a fuel cell membrane humidifier capable of improving humidification efficiency by performing two-stage humidification, and a fuel cell system comprising same. A fuel cell membrane humidifier according to an embodiment of the present invention comprises: a dry air supply means; a fuel cell membrane humidifier which performs two-stage humidification on the dry air supplied from the dry air supply means; a fuel cell stack for generating energy and humid exhaust gas by reacting the humidified air supplied from the fuel cell membrane humidifier with hydrogen; and a bypass flow path for bypassing a portion of the exhaust gas generated in the fuel cell stack. The fuel cell membrane humidifier comprises: a mid-case; a cap which is fastened with the mid-case and has a bypass inlet connected to the bypass flow path; a mixing humidifier which performs mixed humidification by mixing the dry air introduced through the cap and the exhaust gas introduced through the bypass inlet; and at least one cartridge which is disposed in the mid-case and accommodates a plurality of hollow fiber membranes that perform moisture exchange.
