<P>PROBLEM TO BE SOLVED: To provide a humidifier, and a separator capable of suppressing rising of a contact surface pressure between the separator and a water exchange membrane. <P>SOLUTION: The humidifier is provided with a tabular member 1 formed with a passage 1f to be humidified passing oxidation gas to be introduced to a fuel cell, and a humidification passage 1g passing oxidation offgas exhausted from the fuel cell, and the water exchange membrane 2 passing water contents contained in the oxidation offgas passing through the humidification passage 1b, and adding the water contents to the oxidation gas passing through the passage 1f to be humidified. The tabular member 1 and the water exchange membrane 2 are alternately laminated, the passage 1f to be humidified and the humidification passage 1g are provided side by side with the water exchange member 2 in between, and the tabular member 1 has elasticity in a laminated direction. <P>COPYRIGHT: (C)2007,JPO&INPIT |
