Membrane hollow fiber module and method of manufacturing a membrane hollow fiber module, humidifier, fuel cell system and vehicle

摘要

The invention relates to a membrane hollow fiber module for a humidifier of a fuel cell system, in particular of a fuel cell system of a vehicle, having a membrane hollow fiber mat (14) which is wound around a support structure of the membrane hollow fiber module. The support structure has at least one passage opening, via which membrane hollow fibers (10) of the membrane hollow fiber mat (14) can be acted upon by a medium which can be introduced into the membrane hollow fiber module. The membrane hollow fibers (10) form a fabric with a plurality of support threads (12) of the membrane hollow fiber mat (14). The membrane hollow fibers (10) have in the axial direction of the hollow membrane fibers (10) alternating curvature regions (34, 36) in which the respective membrane hollow fiber (10) is meandering around the support threads (12) of the hollow membrane membrane (14) in opposite directions. Furthermore, the invention relates to a humidifier, a fuel cell system, a vehicle and a method for manufacturing a membrane hollow fiber module.
