Major Contributions
 

1. A scalable co-sintering atomic trapping strategy drives Ru migration from CeO₂ into the BSCF perovskite matrix, restructuring heterointerface chemistry and generating coupled interfaces with optimized electron redistribution, oxygen vacancies, and enhanced triple conductivity.

2. The bifunctional electrode achieves a peak power density of 1.51 W cm⁻² in fuel cell mode and electrolysis current density of −2.21 A cm⁻² at 650°C with minimal Ru loading, demonstrating superior performance for reversible protonic ceramic electrochemical cells.

3. Durability over 400 h at 600°C with only 0.09 mV h⁻¹ degradation confirms the strategy as a universal approach for next-generation solid-state energy conversion devices.

主要貢獻
 

1. 可擴展的共燒結原子捕獲策略驅動 Ru 從 CeO₂ 遷移至 BSCF 鈣鈦礦晶格，重構異質界面化學並生成具有優化電子重分佈、氧缺陷及增強三重導電性的耦合界面。

2. 雙功能電極在 650°C 下燃料電池模式峰值功率密度達 1.51 W cm⁻²，電解電流密度達 −2.21 A cm⁻²，且 Ru 用量極低，展現可逆質子陶瓷電化學電池的卓越性能。

3. 在 600°C 下運行 400 小時以上僅有 0.09 mV h⁻¹ 的衰減，確立此策略為下一代固態能源轉換裝置的通用方法。
