<P>PROBLEM TO BE SOLVED: To provide a fuel cell system equipped with a humidifier capable of stably supplying humidified air even at low temperature. <P>SOLUTION: The humidifier 100 has a hollow fiber membrane module 10 consisting of a bunch of hollow fiber membranes coated with a resin layer 12, on an outer periphery of which 12, a metal outer wall layer 16 is put with a constant space set against the resin layer 12. Further, an air heat-insulating layer 14 is formed between the resin layer 12 and the metal outer wall layer 14. An offgas lead-in port 20a, a dry air lead-in port 22a, an offgas drain port 20b, and a humidified air drain port 22b are so made to penetrate the resin layer 12, the air heat-insulating layer 14, and the metal outer wall layer 16, that gas circulation between the outside and the hollow fiber membrane module 10 is possible. <P>COPYRIGHT: (C)2007,JPO&INPIT |
