HUMIDITY ADJUSTER, AND OPERATION METHOD AND EVALUATION METHOD FOR THE HUMIDITY ADJUSTER

摘要

PROBLEM TO BE SOLVED: To provide a humidity adjuster capable of reducing a heat generation amount and to provide an operation method for a humidity adjuster capable of reducing lowering of a dehumidication ability.

SOLUTION: The humidity adjuster is provided with an anion conductive solid electrolyte membrane 9; a cathode catalyst layer 10 provided on a surface at one side of this solid electrolyte membrane 9 and comprising particulates of a metal of platinum group or a metal oxide of the platinum group; a first porous base material 11 provided to contact with this cathode catalyst layer 10; a second porous base material 13 provided on a surface at the other side of the solid electrolyte membrane 9; and an anode catalyst layer 14 provided at an atmosphere side of the solid electrolyte membrane 9 and the second porous base material 13 and comprising particulates of platinum group or a metal oxide of the platinum group. Further, a thin film 13a comprising a metal of the platinum group other than platinum or a metal oxide of the platinum group other than platinum is formed on a surface of the second porous base material 13.
