Abstract

Various embodiments may include an electrolyzer for electrochemical utilization of carbon dioxide comprising: electrolysis cell defining an anode space and a cathode space; an anode in the anode space; a cathode in the cathode space; a first cation-permeable membrane disposed between the anode space and the cathode space; and a second anion-selective membrane disposed between the first cation-permeable membrane and the cathode. The anode directly adjoins the first cation-permeable membrane. The second anion-selective membrane directly adjoins the first cation-permeable membrane and the second anion-selective membrane directly adjoins the cathode.
