Abstract: Described herein is a carbon-efficient bicarbonate electrolyzer and assembly. In some embodiments, an electrolyzer assembly comprises: a cathode disposed in a cathode chamber having ports for receiving a bicarbonate (HCO3−) solution; an anode disposed in an anode chamber having ports for receiving an anolyte; a cation exchange membrane disposed between the cathode chamber and the anode chamber; and a buffer layer disposed between the cathode chamber and the cation exchange membrane. In some embodiments, the electrolyzer assembly is configured to convert the bicarbonate (HCO3−) solution to a formate (OOCH−) solution by movement of cations from the anode to the cathode via the cation exchange membrane.
