Description

technical field [0001] The invention belongs to the technical field of electrochemical dehumidification, and in particular relates to an electrolysis device for capturing gaseous water molecules, a preparation method and its application in electrochemical dehumidification. Background technique [0002] Environmental humidity is closely related to human life and production activities. The level of environmental humidity directly affects human comfort and even human health. The level of environmental humidity also has a crucial impact on industrial production activities and electrical equipment. [0003] At present, there are many mature dehumidification technologies, including solid adsorption dehumidification, membrane dehumidification, heat pump dehumidification, cooling dehumidification, and liquid absorption dehumidification. The principle of solid adsorption dehumidification is basically the same as that of liquid absorption dehumidification. Both use desiccant to absorb...
