This new type of dehumidifier electrolytically decomposes and removes moisture
in a container using a solid polymer electrolyte membrane.

When a direct current is applied to the porous electrode attached to the special solid polymer electrolyte membrane, moisture at the anode side (defumidifying side) is separated into hydrogen ions （H⁺） and oxygen. The hydrogen ions pass through the solid polymer electrolyte membrane to the cathode side (moisture discharging side).

The hydrogen ions react with oxygen in the air on the cathode side to form water molecules(gas) and are then discharged.
