Abstract
(EN)
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.

L’invention concerne un humidificateur de membrane pour une pile à combustible, lequel peut empêcher, sans dispositif de filtrage de gaz séparé, la détérioration de performance d’une pile à combustible causée par des gaz nocifs durant un processus d’humidification. L’humidificateur pour une pile à combustible, selon la présente invention, comprend : une unité de logement comprenant une première entrée de fluide par laquelle entre un premier fluide, une première sortie de fluide par laquelle sort le premier fluide, une deuxième entrée de fluide par laquelle entre un deuxième fluide, et une deuxième sortie de fluide par laquelle sort le deuxième fluide, l’humidité du premier fluide entrant par la première entrée de fluide étant différente de l’humidité du deuxième fluide entrant par la deuxième entrée de fluide ; au moins une première cartouche qui est installée à l’intérieur de l’unité de logement, et dans laquelle une pluralité de membranes à fibres creuses sont accueillies ; et un filtre à gaz qui est disposé à l’intérieur de la première cartouche ou entre la surface circonférentielle intérieure de l’unité de logement et la première cartouche afin de pouvoir collecter des gaz nocifs contenus dans le premier fluide et/ou dans le deuxième fluide, et dont la forme est différente de celle des membranes à fibres creuses.
