Ultra-Fast Microwave-Assisted Volumetric Heating Engineered Defect-Free Ceria/Zirconia Bilayer Electrolytes for Solid Oxide Electrochemical Cells.

ABSTRACT: Solid oxide electrochemical cells (SOCs) hold significant promise as a sustainable energy conversion technology due to their high efficiency and minimal environmental impact. However, their development faces critical challenges, particularly in achieving dense ceria/zirconia bilayer electrolytes necessary to fully leverage state-of-the-art cobaltite-based oxygen electrodes. In this study, a microwave-assisted volumetric sintering process is successfully employed as a transformative alternative to the conventional, time-intensive sintering approach, enabling the fabrication of highly dense ceria/zirconia bilayer electrolytes. This innovative method reduced processing time by over 30-fold compared to convection sintering and achieved a record-low sintering temperature of 1200 °C. SOCs fabric
