Document Type and Number:
WIPO Patent Application WO/2023/228254
Kind Code:
A1
Abstract:
[Problem] To enable regulation of the electrolyte concentration in an electrolytic solution at a sufficiently high accuracy and effectively suppress performance deterioration. [Solution] A carbon dioxide electrolysis apparatus according to an embodiment comprises: a carbon dioxide electrolysis section; an electrolytic solution storage section; an electrolytic solution feed section; an anode cooling·/ gas-liquid separation section; a cathode cooling·/ gas-liquid separation section; a concentration measurement section; and a concentration regulation section. The concentration measurement section measures the electrolyte concentration in the electrolytic solution stored in the electrolytic solution storage section. On the basis of the electrolyte concentration measured by the concentration measurement section, the concentration regulation section carries out regulation whereby the electrolyte concentration in the electrolytic solution stored in the electrolytic solution storage section resides in a preset concentration range.
