Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
1 . A membrane humidifier for a fuel cell, the membrane humidifier comprising: 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 each of the hollow fiber membranes has a plurality of channels formed therein, and a difference between maximum and minimum inner diameters among inner diameters of the plurality of channels is 30 to 600 μm. 2 . The membrane humidifier according to claim 1 , wherein each of the hollow fiber membranes has an outer diameter of 1000 to 5000 μm. 3 . The membrane humidifier according to claim 2 , wherein each of the plurality of channels has an inner diameter of 300 to 1300 μm. 4 . The membrane humidifier according to claim 1 , wherein shortest distances between an outer circumferential surface of each of the hollow fiber membranes and the channels thereof are 60 to 500 μm. 5 . The membrane humidifier according to claim 1 , wherein a sum of sectional areas of the plurality of channels of each of the hollow fiber membranes is 40 to 90% of a sectional area of the hollow fiber membrane.
