Problems solved by technology

Therefore, hollow fiber membranes for humidifiers satisfying the resistance to heat and humidity have a disadvantage of unsatisfactory wettability due to low hydrophilicity
On the contrary, hollow fiber membranes for humidifiers, which exhibit superior wettability due to high hydrophilicity, have low moisture and heat resistance, and thus are not suitable for the case where the humidifier should work for a long time

Embodiment Construction

[0023] Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0024] figure 1 is a schematic diagram illustrating a humidifier for a fuel cell according to an embodiment of the present invention.

[0025] Such as figure 1 As shown, a humidifier for a fuel cell 100 according to an embodiment of the present invention has a housing 110 housing a bundle of a plurality of hollow fiber membranes 120 . The first inlet 111a is located at one side of the housing 110, and a reactant gas (not shown) supplied to the fuel cell enters through the first inlet 111a. The first outlet 112a is located on the other side of the housing 110, and the reactant gas is discharged through the first outlet 112a.

[0026] Both ends of the bundle of hollow fiber membranes 120 are respectively fixed to both sides of the housing 110 by adhesive 130 . The adhesive 130 blocks air flow between the middle of the housing 110 and any one o...

Abstract

Disclosed are a hollow fiber membrane for a humidifier which exhibits superior moisture / heat-resistance and excellent hydrophilicity and can be manufactured at low cost, and a method for manufacturing the same. The hollow fiber membrane includes a tube-type first hydrophilic polymer film having a hollow center, and a second hydrophilic polymer film coated on the inner surface of the tube-type first hydrophilic polymer film. The method includes producing an intermediate hollow fiber membrane from a first hydrophilic polymer material, potting the intermediate hollow fiber membrane in a housing to produce an intermediate hollow fiber membrane module, and coating a second hydrophilic polymer film on the inner surface of the intermediate hollow fiber membrane.

Description

technical field [0001] The present invention relates to a hollow fiber membrane usable for a humidifier of a fuel cell and a method of manufacturing the same. More particularly, the present invention relates to a hollow fiber membrane for a humidifier that exhibits superior heat-and-moisture resistance and excellent hydrophilicity and can be manufactured at low cost, and a manufacturing method thereof. Background technique [0002] A fuel cell is defined as a power generating cell that generates electricity through the combination of hydrogen and oxygen. Unlike general batteries such as dry batteries, storage cells, etc., the advantage of fuel cells is that as long as hydrogen and oxygen are supplied, they can keep generating electricity without heat loss, so the efficiency is about twice that of internal combustion engines. In addition, because fuel cells directly convert the chemical energy produced by combining hydrogen and oxygen into electricity, they release almost no...
