Outline of Final Research Achievements

We improved the metal-based solid oxide electrolysis cell (MS-SOEC) to improve electrolysis performance. A large number of micrometer-order pores for gas diffusion were opened in the metal substrate. Atmosphere plasma spray method (APS) was used for the anode and cathode layers of the SOEC body. A CO2 electrolysis test was performed. We confirmed the production of CO and O2 by electrolysis of the target CO2, and demonstrated that the fabricated cell functions as MS-SOEC. It was judged that the research purpose was achieved by the production of the initially planned MS-SOEC and the demonstration of its operation.

Academic Significance and Societal Importance of the Research Achievements

金属基盤固体酸化物電気分解セル（MS-SOEC）でのCO2電界の報告は他に無く、恐らく世界最初の成果と考えられた。なお、反応時の経時変化をSEM,XRD等で観察、測定し、十分な耐久性を確認した。MS-SOECの実証によりCO2の大規模な資源化に道を開いた。
