Abstract
The present disclosure provides a fuel cell membrane humidifier capable of improving humidification efficiency by increasing a flow time in a humidifying module, and the fuel cell membrane humidifier according to an embodiment of the present disclosure, includes: a mid-case; an off-gas inlet formed in a direction inclined at a predetermined angle with respect to one surface of the mid-case through which off-gas discharged from the fuel cell stack is introduced; and at least one cartridge disposed in the mid-case and including an inner case accommodating a plurality of hollow fiber membranes therein, and a potting part fixing ends of the hollow fiber membranes.
Claims4
A fuel cell membrane humidifier comprising:
- a mid-case;
- an off-gas inlet through which off-gas discharged from the fuel cell stack is introduced, and which is formed in an inclined direction at a predetermined angle with respect to one surface of the mid-case;
- and
- at least one cartridge disposed in the mid-case, and comprising an inner case for accommodating a plurality of hollow fiber membranes therein and a potting part for fixing ends of the hollow fiber membranes,
- wherein the inner case comprises a first mesh hole through which the off-gas flows, and a second mesh hole through which the off-gas introduced through the first mesh hole exchanges moisture and is discharged to an outside, and
- wherein the first mesh hole and the second mesh hole are formed in an asymmetrical shape,
- wherein a total area of mesh hole windows on a side of the first mesh hole is larger than a total area of mesh hole windows on a side of the second mesh hole.
