Title:
GAS RECOVERY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/009859
Kind Code:
A1
Abstract:
An electrochemical cell is configured by stacking and disposing a working electrode (104), a counter electrode (106), a separator (107), a working electrode current collector (103), and a counter electrode current collector (105). The working electrode adsorbs a recovery target gas. The counter electrode performs transfer of electrons with the working electrode. The separator is disposed between the working electrode and the counter electrode and prevents physical contact between the working electrode and the counter electrode to suppress electrical shorting. The working electrode current collector contacts the working electrode and electrically connects the working electrode and the counter electrode. The counter electrode current collector contacts the counter electrode and electrically connects the working electrode and the counter electrode. A counter electrode surrounding member is disposed to the electrochemical cell so as to cover the counter electrode and the counter electrode current collector, and suppresses contact between the mixed gas and the counter electrode.
