Abstract (en)
[origin: WO2019011577A1] The invention relates to a method for the electrolysis of CO2, wherein the electrolytic cell has a salt bridge space, having a fluid and/or dissolved acid, said electrolytic cell comprising: a cathode chamber having a cathode; a first ion exchanger membrane containing an anion exchanger and/or an anion transporter and adjacent to the cathode chamber, wherein the cathode directly contacts the first ion exchanger membrane; an anode chamber having an anode; and a diaphragm adjacent to the anode chamber; wherein a salt bridge space is also provided, which is arranged between the first ion exchanger membrane and the diaphragm. The invention also relates to an electrolysis system comprising the electrolytic cell, and the use of the electrolytic cell or the system for the electrolysis of CO2.
