Article Description

Protonic ceramic fuel cells (PCFCs) have garnered significant interest due to their theoretically high fuel utilization and excellent energy efficiency at intermediate temperatures (400–600 °C). While the performance of PCFCs has improved dramatically in recent years, the system electrical efficiency is often lower than the corresponding cell energy efficiency due to energy loss in a PCFC system. This study focuses on achieving >70% system electrical efficiency (lower heating value-LHV) in a H 2 -powered PCFC system. The required property values such as the conductivities and diffusion coefficients of proton and hole in the electrolyte, as well as the exchange current densities and reaction resistances at electrodes are revealed through a validated numerical model compared to the experimental results of a high-performance PCFC. It offers significant empirical insights for advancing high-performance PCFCs capable of achieving >70% system electrical efficiency.
