example 1

[0109] 20 wt% of polyethersulfone (PES) and 20 wt% of dimethylacetamide were introduced into the reaction vessel, and stirred at a temperature of 70° C. for 6 hours to prepare a hollow fiber membrane-forming composition (coating solution ( dope)).

[0110] In addition, 50 wt% of water and 50 wt% of DMAC were mixed with each other to prepare an internal coagulation solution for dry spinning and wet spinning. The coating solution and the coagulation solution were injected into a double-tube type nozzle to manufacture a hollow fiber membrane.

[0111] 2000 hollow fiber membranes fabricated as described above were arranged in a single bundle in a prismatic body part (having a width of 40 mm, a depth of 300 mm, and a height of 200 mm), the opposite ends of which were formed by potting cells It was covered with a cap, and a composition for potting was injected into the gap between the hollow fiber membranes, and the gap between the hollow fiber membrane bundle and the main body par...

example 2

[0118] A membrane humidifier was fabricated in the same manner as in Example 1 except that charcoal was used as the pollutant-retaining material.

example 3

[0120] A membrane humidifier was manufactured in the same manner as in Example 1 except that sulfonated polyethersulfone (S-PES) was used as the pollutant-retaining material.

Abstract

The present invention relates to a composite hollow fiber membrane, a manufacturing method therefor, a hollow fiber membrane cartridge including same, and a fuel cell membrane humidifier, the composite hollow fiber membrane comprising a hollow fiber membrane and a contaminant collection layer coated on the inner surface of the hollow fiber membrane. The composite hollow fiber membrane can preventperformance deterioration of a fuel cell by removing, without a separate gas filtering device, contaminants such as nitrogen oxide (NOx), sulfur oxide (SOx), and ammonia (NH3) during a humidifying process.

Description

technical field [0001] The present disclosure relates to a composite hollow fiber membrane, a manufacturing method of the composite hollow fiber membrane, a hollow fiber membrane cartridge including the composite hollow fiber membrane, and a fuel cell membrane humidifier, and more particularly, to a In the case of gas filtration devices, during humidification processes such as nitrogen oxides (NO x ), sulfur oxides (SO x ) or ammonia (NH 3 ), a composite hollow fiber membrane that prevents performance degradation of a fuel cell, a method for manufacturing the composite hollow fiber membrane, a hollow fiber membrane cartridge including the composite hollow fiber membrane, and a fuel cell membrane humidifier. Background technique [0002] A fuel cell is a power generation battery 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, it can continuousl...
