The material is not hygroscopic. Therefore, in the initial stage of driving the dehumidifying element, sufficient operation is not exhibited until the surface of the solid polymer electrolyte membrane 3 becomes wet, and the dehumidifying operation due to electrolysis of water does not proceed smoothly, so that the initial driving characteristics vary. There was a drawback that it caused. Also, the anode 1
The platinum plating for plating the stainless steel fiber has a film thickness of several μm or less, and it is unavoidable that minute holes are generated in the plating process.

Since the dehumidifying operation by the electrolysis of water is smoothly performed even at the time of the initial driving of the dehumidifying element, the disadvantage that the initial driving characteristics vary can be solved. Further, when the porous base material of the anode is formed of platinum-plated titanium fiber, there is no risk of metal ions being eluted from the minute pores formed in the platinum-plated film and damaging the solid polymer electrolyte membrane. Stable drive characteristics can be obtained over a period of time.
