Understanding of CO₂ Electrochemical Reduction Reaction Process via High Temperature Solid Oxide Electrolysers

The CO 2 electrochemical reduction via SOEC was studied at a range of cathode materials in various operational conditions. The influences of the fuel gas composition, operating potential and temperature on cathode behavior were discussed and compared on different cathodes. The dissociative adsorption and surface diffusion of active species from CO 2 reduction reaction was found to contributed dominantly to the LSCM-based cathode working in CO 2...
