Protonic ceramic fuel cells(PCFCs)can work in low temperatures and efficiently utilize and store hydrogen energy. But their commercial application is hampered by the poor battery stability.Under current stage,many PCFC present inferior long-term stability while presenting excellent activity. This study emphasizes on the significance of PCFCs′ stability in academic researches and practical applications. The intrinsic factors influencing the stability of the key components of PCFCs,electrolytes and electrodes,were expounded based on their material analyses. The analyses point out that the key to the breakthroughs of batteries′ performances lay in improving the stability of the electrolyte and electrode materials. This work will be helpful for exploring the fundamental reasons for the cells′ degeneration and provide more reliable references from cell stability improvement in engineering cases.
