Outline of Final Research Achievements

Efficient carbon dioxide (CO2) reduction into carbon material is required to establish a smart enegy system using unstable electricity production from solar, wind and so fourth renewable energy systems. Direct electrolysis of CO2 was discussed experimentally. A disk-type solid oxide electrolysis cell (SOEC) was prepared and examined experimentally for application to the CO2 reduction process. The electrolysis of carbon dioxide was conducted at 800-900 degree C. A current density of 107.1 mA cm-2 was measured between the cathode and anode at 900 deg. C and at 2.52 V. The production rates of carbon monoxide ar a carbon material and oxygen were in agreement with the theoretical values determined using Faraday’s law. It was demonstrated that the SOEC methodology is useful for utilization of large amount and unstable renewable energies.
