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 prevent performance deterioration of a fuel cell by removing, without a separate gas filtering device, contaminants such as nitrogen oxide (NO), sulfur oxide (SO), and ammonia (NH) during a humidifying process.
