近年来，无污染、可再生的固体氧化物燃料电池（SOFC）以其高能效、燃料选择灵活等优点成为下一代可再生能源的有力候选者。然而，传统观点认为，只有在高温下才能保证电解液中氧离子的快速输运，从而降低电压损失，进而决定SOFC的电性能。本文报道了一种现场非接触式监测SOFC工作状态的方法，该方法有望成为一种很有前途的光学温度传感器，用于检测电解质材料的工作温度。采用密度泛函理论计算与上转换发光相结合的方法，研究了La 2 Mo 2 O 9衍生物中热驱动形成的O-离子Frenkel对（自然增溶剂）与Bi 3+掺杂（竞争性抑制剂）之间的纠缠，特别是在未来SOFC器件所需的较低温度下。这是在不牺牲电气性能的情况下筛选和表征候选电解质在较低温度下发生的潜在途径。
Nowadays, by no means fortuitous, pollution-free and bio-regenerative solid oxide fuel cells (SOFCs) have arisen to be a competitive candidate as next generation renewable energy, which exhibiting high energy efficiency and flexible fuel choices. However, fast oxide-ion transportation of electrolyte could only be ensured in high working temperature by conventional views, which can decrease the voltage loss and further determine the electrical performance of SOFCs. Herein we report an in-situ and non-contact method to monitor the working condition of SOFCs and it is potential to become a promising optical temperature sensor to detect the working temperature of electrolyte materials. With the combinative protocol between density functional theory calculation and upconversion (UC) luminescence, the entanglement between thermal-driven formed O-ion Frenkel pair (native solubilizer) and Bi3+dopant (competitive inhibitor) in La2Mo2O9derivatives has been unraveled, especially at a lower temperature required by a future SOFCs device. It is a potential route for screening and characterizing the candidate electrolyte onsets in lower temperature without sacrificing electrical performance.
