摘要
质子陶瓷燃料电池(PCFC)工作温度较低,可高效利用和储存氢能,但要实现其大规模应用,需从根本上解决电池稳定性问题。目前很多此类电池的长期工作稳定性表现不佳,众多材料在表现出高活性的同时,长期工作稳定性却面临巨大挑战,成为PCFC大规模应用的障碍。强调了电池稳定性在PCFC研究和实际应用中的重要性,从材料角度剖析了引起电池重要组件(电解质和电极)稳定性变化的内在原因,指明了在改善电解质和电极材料稳定性方面可能的关键突破点,挖掘电池稳定性衰减的科学根源,并为今后从工程上改善电池稳定性问题提供更多思路。
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.
