COMPOSITE HOLLOW FIBER MEMBRANE METHOD FOR MANUFACTURING THE SAME HOLLOW FIBER MEMBRANE CARTRIDGE AND MEMBRANE HUMIDIFIER FOR FUEL CELL COMPRISING THE SAME

摘要

The present invention relates to a composite hollow fiber membrane, a manufacturing method thereof, a hollow fiber membrane cartridge and a fuel cell membrane humidifier comprising the same. The composite hollow fiber membrane includes a hollow fiber membrane and a contaminant trapping layer coated on an inner surface of the hollow fiber membrane. The composite hollow fiber membrane is able to prevent degradation of performance of a fuel cell by removing contaminants such as nitrogen oxide (NO_x) sulfur oxide (SO_x), ammonia (NH_3) and the like during a humidifying process without additional gas filter devices.
