HUMIDIFYING MODULE

摘要

PROBLEM TO BE SOLVED: To provide a humidifying module which generates no pool at its bottom part even when a fluid in which steam and condensed water coexist is made to flow in an inner passage and which has excellent output respondency and excellent starting property of a fuel cell even when applied to humidification of supply gas supplied to the fuel cell in a humidifying module which accommodates hollow fiber membrane bundles of water transmissive type inside and is provided with the inner passage with a bottom at its nearly central part. SOLUTION: The humidifying module 1 is provided with the hollow fiber membrane bundle 1b through which water can be exchanged between fluids respectively flowing inside and outside the membrane and the inper passage (a pipe 2) with the bottom which has an entrance part 2a and an exit part 2b through which the fluid can go in and out and extends in a longitudinal direction with length shorter than that of the hollow fiber membrane bundle at nearly central part in a thickness direction of the hollow fiber membrane bundle 1b. Further a projected part 2c is provided in a direction against the fluid flow at a bottom bs provided near the exit part 2b of the inner passage (the pipe 2).
