| Abstract Scope |
Solid Oxide Fuel Cells (SOFCs) are a promising power generation technology. Their high operating temperature enables thermal integration in hybrid systems, such as with gas turbines. However, performance degradation over time is a key barrier to wider adoption. This degradation results from the interplay of three operational parameters—temperature, fuel utilization, and current density. While models suggest SOFC lifetime could improve by up to ten times, there is a notable lack of experimental data directly linking degradation to these parameters. This study addresses that gap by providing quantitative experimental data correlating SOFC degradation with these three parameters under steady-state and dynamic conditions. Post-test material characterization is also conducted to identify the physical and chemical changes responsible for, or resulting from, performance loss. Insights from this work support the development of more durable SOFC materials, as well as improved design and operational strategies, thereby enhancing reliability and enabling long-term commercial deployment. |
