Abstract
(EN)
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.

L'invention concerne un humidificateur à membrane pour une pile à combustible, comprenant des membranes à fibres creuses à canaux multiples ayant une pluralité de canaux de différentes tailles, ce qui permet de maintenir les performances d'humidification dans le cas d'un débit élevé et d'être réduite dans le cas d'un faible débit d'écoulement, et d'empêcher ainsi une inondation. L'humidificateur à membrane pour une pile à combustible, selon la présente invention, comprend : un boîtier intermédiaire dans lequel une pluralité de membranes à fibres creuses sont reçues; un boîtier à capuchon couplé au boîtier central; et une unité de fixation dans laquelle les extrémités de la pluralité de membranes à fibres creuses sont empotées, une pluralité de canaux étant formés dans chacune des membranes à fibres creuses, et la différence entre les diamètres internes les plus grands et les plus petits parmi les diamètres internes de la pluralité de canaux étant de 30 à 600 µm.
