Title
(EN) MEMBRANE HUMIDIFIER FOR FUEL CELL
(KO) 연료전지용 막가습기
Abstract
(EN)
Disclosed is a membrane humidifier for a fuel cell, capable of preventing performance of the fuel cell from being lowered by removing nitrogen oxide (NO_x), sulfur oxide (SO_x), and ammonia (NH_3), during humidification without a separate gas filter device. According to the present invention, a humidifier for a fuel cell includes: a housing having a first fluid inlet to introduce a first fluid, a first outlet to discharge the first fluid, a second fluid inlet to introduce a second fluid, and a second fluid outlet to discharge the second fluid, in which the humidity of the first fluid introduced through the first fluid inlet is different from the humidity of the second fluid introduced through the second fluid inlet; at least one first cartridge installed inside the housing to receive a plurality of hollow fiber membranes; and a gas filter provided in the first cartridge or interposed between an inner circumferential surface of the housing and the first cartridge, configured to collect toxic gas contained in at least of the first fluid and the second fluid, and having a shape different from those of the hollow fiber membranes, in which the toxic gas includes nitrogen oxide (NO_x), sulfur oxide (SO_x), ammonia (NH_3), or the mixture of at least two types of gas described above.
