The present invention relates to a humidifier for a fuel cell which improves gas flow inside a membrane module having dry air and wet air introduced thereinto in order to enhance humidification efficiency of a hollow fiber membrane so as to promote efficiency of power generation and improved durability of a stack of the fuel cell. According to the present invention, the humidifier for the fuel cell comprises: a membrane module having a hollow fiber membrane fixed into a case in a bundle shape, and first and second housings assembled at both ends of the case respectively, wherein a dry air supply pipe is installed to form gas flow in the same direction as the hollow fiber membrane in the membrane module, and one or more wet air pumping units are equipped at one side of the dry air supply pipe to suck wet air flowing along an outer side of the dry air supply pipe by flow rate and fluid pressure of the dry air, thereby improving humidification performance of humidified air discharged to the stack of the fuel cell. |
