Identification of Material Properties of Proton Conducting Solid Oxide Fuel Cells after Reverse Operation

Abstract

This paper investigates the material properties and performance of proton conducting solid oxide fuel cells (SOFCs) after reverse operation, emphasizing their role in sustainable energy. Focusing on their high-efficiency and low-environmental impact, the study explores these SOFCs in electrolysis mode for hydrogen production, highlighting their enhanced ionic conductivity at intermediate temperatures (600-700°C). Key findings include insights into material changes during operation, identified through advanced X-ray imaging, and the determination of initial and final porosity values in the anode layers, crucial for cell optimization. This research contributes significantly to the understanding of proton conducting SOFCs, offering a foundation for future advancements in sustainable energy technologies and their commercialization.
