Method and System for Electrochemical Reduction of Carbon Dioxide Employing a Gas Diffusion Electrode

摘要

The present disclosure is a method and system for the reduction of carbon dioxide. The method may include receiving hydrogen gas at an anolyte region of an electrochemical cell including an anode, the anode including a gas diffusion electrode, receiving an anolyte feed at an anolyte region of the electrochemical cell, and receiving a catholyte feed including carbon dioxide and an alkali metal bicarbonate at a catholyte region of the electrochemical cell including a cathode. The method may include applying an electrical potential between the anode and cathode sufficient to reduce the carbon dioxide to at least one reduction product.
