HUMIDIFICATION DEVICE FOR FUEL CELL

摘要

PURPOSE: A membrane humidifier for fuel cell is provided to improve moisturizing efficiency of dry air flowing in a center part of a hollow fiber membrane by allowing wet air to easily penetrate into the center part of the hollow fiber membrane module through an inner penetrative channel. CONSTITUTION: A membrane humidifier for fuel cell comprises a hollow type housing(101) in which a plurality of wet air inlets(104) are formed to penetrate along a circumference of one end, and a hollow fiber membrane module arranged inside the housing. Near the wet air inlets, internal penetrative channels extended to inside the housing is formed to one body in order to supply wet air to a center part of the hollow fiber membrane module along the internal penetrative channels. The internal penetrative channels are formed between the wet air inlets.
