Document Type and Number:
WIPO Patent Application WO/2022/019065
Kind Code:
A1
Abstract:
One aspect of the present invention provides an acidic gas separation device which is provided with an electrolyte layer, a pair of electrodes that are arranged so as to have the electrolyte layer sandwiched therebetween, and a voltage application unit that applies a voltage between the pair of electrodes, wherein: the pair of electrodes are gas permeable electrodes; and the electrolyte layer contains a nonvolatile electrolyte solution and at least one compound that is selected from the group consisting of high molecular weight redox compounds having a radicalization rate of 90% or more, high molecular weight redox compounds having a quinone group in each molecule, and high molecular weight redox compounds having an imino group in each molecule.
