HUMIDIFIER FOR FUEL CELL AND METHOD FOR MANUFACTURING SAME

Disclosed are: a humidifier for a fuel cell, which can reliably prevent gas leaks due to repeated operations and shutdowns of a fuel cell and can be manufactured with relatively low manufacturing costs and high productivity as well; and a method for manufacturing same. A humidifier for a fuel cell of the present invention comprises a humidification module and caps coupled to both ends of the humidification module, respectively. The humidification module comprises: a mid-case having a step on the inner peripheral surface thereof; a plurality of hollow fiber membranes in the mid-case; a fixation layer on which ends of the hollow fiber membranes are potted; a bracket which is supported by the step of the mid-case and is in contact with the fixation layer; and a packing member in contact with the bracket and having a groove into which an end of the mid-case is inserted.
