Abstract: An electrolytic cell includes a cation exchange membrane, a cathode compartment, and an anode compartment. The cathode compartment includes a gas diffusion electrode and a flow channel element, in which the flow channel element is between the cation exchange membrane and the gas diffusion electrode, and has a plurality of flow channels arranged in parallel with each other. The anode compartment includes an anode mesh, in which the cation exchange membrane is between the anode mesh and the flow channel element. A distance between the anode mesh and the gas diffusion electrode is substantially equal to the sum of a first thickness of the cation exchange membrane and a second thickness of the flow channel element. The novel electrolytic cell can combine with a chloralkali electrolytic cell to deal with gaseous CO2 and produce products, e.g., synthesis gas, for other purposes.
