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 for a fuel cell, according to the present invention, comprises: a housing unit comprising a first fluid inlet via which a first fluid flows in, a first fluid outlet via which the first fluid flows out, a second fluid inlet via which a second fluid flows in, and a second fluid outlet via which the second fluid flows out, wherein the humidity of the first fluid flowing in via the first fluid inlet is different from the humidity of the second fluid flowing in via the second fluid inlet; at least one first cartridge which is installed inside the housing unit, and in which a plurality of hollow fiber membranes are accommodated; and a gas filter which is provided inside the first cartridge or between the inner circumferential surface of the housing unit and the first cartridge so as to be able to collect harmful gases contained in the first fluid and/or the second fluid, and which has a different shape from the hollow fiber membranes.
