<P>PROBLEM TO BE SOLVED: To realize a means for maintaining humidity in a humidification module by a simple composition. <P>SOLUTION: The humidification module 1a is installed in a gas passage (a wet gas passage). In the humidification module 1a, hollow fiber membranes 10a are plurally bundled. In the hollow fiber members 10a, a cylinder is formed by membranes having micropores permeating water contents, and by passing gas passing through the gas passage through an inner side or outer side of the cylinder, humidification of the gas is carried out. The humidification module 1a is provided with water content adjusting materials 30a-1 and 30a-2 provided so as to contact the bundle of the hollow fiber membranes 10a. The water content adjusting materials 30a-1 and 30a-2 have water retentivity for retaining water contents, and they discharge water contents to the hollow fiber membranes 10a or absorb water contents of the hollow fiber membranes 10 in response to a water content amount of the hollow fiber membranes 10a. <P>COPYRIGHT: (C)2008,JPO&INPIT |
