GAS PHASE ELECTROCHEMICAL REDUCTION OF CARBON DIOXIDE

摘要

Methods and systems for gas phase electrochemical reduction of carbon dioxide are disclosed. A method for gas phase electrochemical reduction of carbon dioxide may include, but is not limited to, steps (A) to (C). Step (A) may include introducing a substantially gas phase fuel to an anode flow field of an anode of a proton exchange membrane (PEM) fuel cell. Said anode may be a gas diffusion electrode. Step (B) may include introducing a substantially gas phase carbon dioxide to a cathode flow field of a cathode of said PEM fuel cell. Said cathode may be a chemically modified gas diffusion electrode including a coating of a polymer aromatic amine. Step (C) may include reducing at least a portion of said substantially gas phase carbon dioxide to a product mixture at said cathode.
