    Abstract: The present invention relates to a humidifier for a fuel cell, the humidifier comprising: a humidifying module for humidifying a dry gas, supplied from the outside, by using a wet gas discharged from a fuel cell stack; and a first cap coupled to one end of the humidifying module. The humidifying module includes: a mid-case; and at least one cartridge disposed in the mid-case and accommodating a plurality of hollow fiber membranes. The humidifier for a fuel cell further includes a first packing member which is air-tightly coupled to at least one end of the humidifying module through mechanical assembly so that the first cap is in fluid communication with only the hollow fiber membranes.

    Abstract: Disclosed is a membrane humidifier for a fuel cell, comprising multi-channel hollow fiber membranes having a plurality of channels in various sizes, thus allowing humidifying performance to be maintained in the case of a high rate of flow and to be decreased in the case of a low rate of flow, and thereby preventing flooding. The membrane humidifier for a fuel cell, according to the present invention, comprises: a middle case in which a plurality of hollow fiber membranes are accommodated; a cap case coupled to the middle case; and a fixing unit in which ends of the plurality of hollow fiber membranes are potted, wherein a plurality of channels are formed in each of the hollow fiber membranes, and the difference between the biggest and smallest inner diameters among the inner diameters of the plurality of channels is 30-600 μm.

    Abstract: Disclosed is a membrane humidifier for a fuel cell, which can prevent, without a separate gas filtering device, performance deterioration of a fuel cell due to harmful gases during a humidifying process. The humidifier comprises: a housing unit comprising a first fluid inlet, a first fluid outlet, a second fluid inlet, and a second fluid outlet, wherein the humidity of the first fluid introduced via the first fluid inlet is different from the humidity of the second fluid introduced via the second fluid inlet; at least one first cartridge installed inside the housing unit, the first cartridge having a plurality of hollow fiber membranes therein; and a gas filter provided in the first cartridge or between the inner circumferential surface of the housing unit and the first cartridge so as to capture harmful gases contained in the first or second fluid.

    Abstract: A humidifier for a fuel cell is provided and includes a housing having, at a first side, a moist air supply port through which moist air is supplied from a fuel cell stack and having, at a second side, a moist air discharge port. A humidifying membrane is disposed in the housing and allows dry air to flow along the inside of the humidifying membrane. A bypass flow path is formed in the housing to allow a part of the moist air supplied to the moist air supply port to continuously flow to the moist air discharge port without passing through the humidifying membrane, thereby adjusting the amount of humidification and a differential pressure of the humidifier based on an operating condition of a fuel cell.
