Title:
GAS-PHASE REDUCTION APPARATUS FOR CARBON DIOXIDE, AND METHOD FOR PRODUCING POROUS REDUCTION ELECTRODE-SUPPORTED ELECTROLYTE MEMBRANE
Document Type and Number:
WIPO Patent Application WO/2022/113277
Kind Code:
A1
Abstract:
This gas-phase reduction apparatus 100 for carbon dioxide is provided with an oxidation vessel 1 which contains an oxidation electrode 2, a reduction vessel 4 which is arranged adjacent to the oxidation vessel 1 and into which carbon dioxide is supplied when the inside of the reduction vessel 4 is empty, and a porous reduction electrode-supported electrolyte membrane 20 which is arranged between the oxidation vessel 1 and the reduction vessel 4, in which the porous reduction electrode-supported electrolyte membrane 20 is a joined body that is formed by joining a porous reduction electrode 5 formed by dispersing a first electrode membrane in an inside void to a second electrolyte membrane 6, the second electrolyte membrane 6 is arranged on the oxidation vessel 1 side, the porous reduction electrode 5 is arranged on the reduction vessel 4 side and is connected to the oxidation electrode 2 through a conducting wire 7, and the reduction reaction of the carbon dioxide in the reduction vessel 4 is performed by the action of electrons flowing through the conducting wire 7.
