A Nafion membrane humidifier for a fuel cell is provided to increase the retention time of dry air inside the humidifier or to increase the contact area with dry air, thereby improving the humidifying efficiency. A Nafion membrane humidifier for a fuel cell comprises: a housing including an inlet through which dry reaction gases to be supplied to a fuel cell stack is introduced, an outlet for supplying gases containing moisture after the reaction to the fuel cell stack, a sub-inlet through which unreacted gases containing moisture and discharged from the fuel cell stack is introduced, and a sub-outlet through which gases remaining after the reaction is discharged; and a Nafion tube bundle(110) formed by a plurality of Nafion tubes(112) receiving several thousands of hollow fibers(114) carrying out moisture exchange when the reaction gases pass therethrough, and received in the housing while forming an eddy-like structure by being wound successively from one side. |
