Membrane Humidifier for Fuel Cells

A membrane humidifier (100) for a fuel cell, the membrane humidifier (100) comprising:

• a first housing (10) comprising a humidity inlet port (12) configured to suction a wet flow thereinto and a dry air outlet port (14) configured to discharge dry air;
• a second housing (80) correspondingly coupled to the first housing the first housing, and comprising a humidity outlet port configured to discharge a wet flow and a dry air inlet port configured to suction dry air;
• and a cartridge (40) located inside the first housing (10) and the second housing (80),
• wherein inside the cartridge (40), a flow path through which the wet flow is suctioned or discharged is provided into any one selected among a first path through which the wet flow moves forward at an upper portion and moves downward and then is discharged toward a lower outlet, or a second path through which the wet flow moves forward at a lower portion and moves upward and then is discharged toward an upper outlet, thereby providing a structure in which turbulence generated between the first housing (10) or the second housing (80) and the cartridge (40) is reduced and vibrations or external force applied to a hollow fiber membrane is reduced.
