▎ 摘　　要

NOVELTY - A gas separator comprises a pair of electrodes, an electrolyte component arranged between the electrodes, and a connection component that electrically connects the electrodes to a power source. The electrodes or the electrolyte component each has a gas medium having bondability with a predetermined gas type changes due to a redox reaction. The electrolyte component comprises a non-aqueous electrolytic liquid. The non-aqueous electrolytic liquid comprises an ionic liquid or a solvated ionic liquid, and 80 %mass or less low-viscosity solvent exhibiting a lower viscosity than that of the ionic liquid or solvated ionic liquid. USE - Gas separator used in gas system (claimed) for separating gas such as carbon dioxide in air and exhaust gas discharged from boiler, incinerator, diesel engine, gas engine, internal combustion engine such as gas turbine. ADVANTAGE - The gas separator has improved energy efficiency with respect to the charged electric power. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a gas system. DESCRIPTION OF DRAWING(S) - The drawing shows a typical view of the gas separator.
