Abstract

A membrane humidifier for a fuel cell, according to one embodiment 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; a potting part formed at the end portions of the plurality of hollow fiber membranes; and an assembling member disposed between the end portions of the cap case and the middle case, and simultaneously coupling, so as to be airtight, a gap between the cap case and the middle case and a gap between the cap case and the potting part.

Description

technical field [0001] The present invention 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-generating battery that combines hydrogen and oxygen to produce electricity. Such a fuel cell has the advantage that electricity can be continuously generated as long as hydrogen and oxygen are supplied, unlike common chemical cells such as dry cells or storage batteries, and there is no heat loss, whereby the efficiency of the fuel cell is about twice that of an internal combustion engine. [0003] In addition, the fuel cell directly converts chemical energy generated through the combination of hydrogen and oxygen into electrical energy, thereby emitting a small amount of pollutants. Therefore, the fuel cell has an...
