Title:
GAS RECOVERY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/047983
Kind Code:
A1
Abstract:
A gas recovery system for separating out gas to be recovered from mixed gas by an electrochemical reaction, the system comprising a housing (100) and one or more electrochemical cells (101). The electrochemical cell has a working pole (104) and an antipole (106). The housing has a gas inflow section (100b) for letting the mixed gas flow into the interior, and a gas outflow section (100c) for letting the mixed gas flow out from the interior. Applying a voltage between the working pole and the antipole makes it possible to cause the working pole to adsorb the gas to be recovered that is contained in the mixed gas. The gas inflow section has a shape where the opening surface area becomes smaller going toward the downstream side of a direction of gas flow in which the mixed gas flows from the gas inflow section toward the gas outflow section.
