Abstract

A membrane humidifier for a fuel cell, of 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; potting parts formed at the ends of the plurality of hollow fiber membranes; an assembly member disposed between the cap case and the end of the middle case so as to provide air tight coupling therebetween;and a protrusion part extending toward the edges of the potting parts from the inside of the cap case so as to provide air tight coupling between the cap case and the potting parts.

Description

technical field [0001] The present disclosure relates to a membrane humidifier for a fuel cell, and more particularly, to a membrane humidifier for a fuel cell capable of performing an airtight sealing function in a high temperature / high pressure / high humidity environment through a mechanical assembly structure. Background technique [0002] A fuel cell is a power generation cell that combines hydrogen and oxygen to generate electricity. The advantage of this type of fuel cell is that, unlike ordinary chemical cells such as dry cells or storage batteries, electricity can be continuously generated as long as hydrogen and oxygen are supplied, and there is no heat loss, whereby the efficiency of the fuel cell is about twice as high as that of an internal combustion engine . [0003] In addition, the fuel cell directly converts chemical energy generated by the combination of hydrogen and oxygen into electrical energy, thereby emitting a small amount of pollutants. Therefore, t...
