<P>PROBLEM TO BE SOLVED: To provide a humidifier capable of improving humidifying efficiency compared to a conventional one. <P>SOLUTION: The humidifier includes a hollow fiber membrane bundle 20 formed by bundling a plurality of hollow fiber membranes 18, and a case 16 for storing the hollow fiber membrane bundle 20. The hollow fiber membrane bundle 20 is provided inside with mesh 22 formed in substantially arch shape rising upward in opposition to a downward flow direction of cathode off-gas and allowing the cathode off-gas to pass through while supporting load applied to the hollow fiber membranes 18 to suppress deformation of the hollow fiber membrane bundle 20 when the cathode off-gas flowing in from an off-gas inflow part 30 flows through outside the hollow fiber membranes 18. <P>COPYRIGHT: (C)2010,JPO&INPIT |
