| Outline of Final Research Achievements |
A system in which water vapor and carbon dioxide are supplied to a solid oxide cell for co-electrolysis can synthesize hydrocarbon fuels with high energy efficiency from a simple process, and is expected to be a highly infrastructure-compatible fuel production and power load leveling device from renewable energy sources. However, the steam/carbon dioxide electrolysis and reverse aqueous shift reactions are endothermic reactions, and the factors affecting the temperature and reaction distribution in the cell are complex. Therefore, we have developed a multiphysics analysis scheme for the electrolysis, reaction, and temperature distribution in a solid oxide cell during co-electrolysis, and organized the dominant factors for its performance.
