Disclosed is an electrochemical dehumidification device based on a screen-type amphoteric ion exchange membrane electrode, comprising a core dehumidification unit which comprises, sequentially from one side to the other side, an anode air pathway, a screen-type anode electrode, an amphoteric ion exchange membrane, a screen-type cathode electrode and a cathode air pathway. The core dehumidification unit performs active dehumidification when a voltage is applied, and performs passive dehumidification when no voltage is applied. A number of the core dehumidification unit is equal to or more than one, the core dehumidification units are capable of being connected in parallel, in serial or in an overlapping mode; meanwhile, the units may also be used in combination with other dehumidification devices. The device achieves active/passive dehumidification, and is ultra-compact and flexible.

The present invention relates to a photocatalytic power generation apparatus depending on an ambient humidity difference. The power generation apparatus comprises a photocatalytic power generation unit driven by a humidity difference, a power storage assembly and a sunlight collection and emission assembly. The photocatalytic power generation unit driven by the humidity difference comprises an anode gas channel, a screen type photoelectric anode material, a moisture-permeable proton exchange membrane, a screen type cathode material and a cathode gas channel in sequence from one side to the other side. The photocatalytic power generation unit of the apparatus converts gas humidity difference potential energy in the anode and cathode gas channels into electric energy by a photocatalytic electrochemical reaction under an illumination condition and stores the converted electric energy into the power storage assembly.
