DEHUMIDIFYING ELEMENT

摘要

PURPOSE: To improve initial driving property of a dehumidifying element in which a solid high polymer electrolyte film is inserted between an anode and a cathode and also to prevent the solid high polymer electrolyte film from being damaged due to elution of metal ions from the anode of the dehumidifying element. CONSTITUTION: Hydrophilic oxide such as silica gel is deposited on a porous base material 11 forming an anode of a dehumidifying element, thereby hygroscopicity of the porous base material 11 is enhanced to prompt wetting of a solid high polymer electrolyte film 3. Further, elution of metal ions from fine holes formed in a coating film of the platinum plating is prevented by forming the porous base material 11 with a platinum-plated titanium fiber.
