CO2 DECOMPOSITION VIA OXYGEN DEFICIENT FERRITE ELECTRODES USING SOLID OXIDE ELECTROLYSER CELL

摘要

Oxygen Deficient Ferrites (ODF) electrodes integrated with Yttria Stabilized Zirconia (YSZ) electrolyte, electrochemically decompose carbon dioxide (CO₂) into carbon (C)/carbon monoxide (CO) and oxygen (O₂) in a continuous process. The ODF electrodes can be kept active by applying a small potential bias across the electrodes. CO₂ and water (H₂O) can also be electrolyzed simultaneously to produce syngas (H₂+CO) and O₂ continuously that can be fed back to the oxy-fuel combustion. With this approach, CO₂ can be transformed into a valuable fuel source allowing CO₂ neutral use of the hydrocarbon fuels.
