随着全球能源消耗的加速增长，清洁，高效的能源转换和存储系统的开发变得越来越重要。固态氧化物燃料电池（SOFC）作为一种重要的燃料电池，由于其高能量转换效率和低排放而备受关注。但是，由于SOFC的工作温度苛刻（800-1000°C），出现了一些严重的问题，例如差的热机械稳定性和难于密封的特性，导致SOFC的寿命短和成本高。因此，将SOFC的工作温度降低到中档甚至是低档已成为近年来SOFC开发的主要目标之一。寻找具有较高电催化活性和在较低温度下具有稳定稳定性的新型阴极材料，是中低温SOFC（ILT-SOFC）的基本要求之一。在过去的15年中，我们为ILT-SOFC的替代阴极材料的开发投入了大量精力。在这篇综述中，我们总结了这些努力的进展。我们首先总结了为降低SOFC的工作温度而开发的具有高活性和耐久性的阴极材料的几种策略。然后，提供了关于阴极活性和稳定性方面的新思想和新进展。讨论了传导氧离子的SOFC的阴极和传导质子的SOFC的阴极。最后，我们概述了机遇，挑战，

Toward Reducing the Operation Temperature of Solid Oxide Fuel Cells: Our Past 15 Years of Efforts in Cathode Development

The development of clean and efficient energy conversion and storage systems is becoming increasingly vital as a result of accelerated global energy consumption. Solid oxide fuel cells (SOFCs) as one key class of fuel cells have attracted much attention, owing to their high energy conversion efficiency and low emissions. However, some serious problems appeared because of the scorching operating temperatures of SOFCs (800–1000 °C), such as poor thermomechanical stability and difficult sealing, resulting in a short lifespan and high cost of SOFCs. Therefore, lowering the operating temperature of SOFCs to mid-range and even low range has become one of the main goals for SOFC development in the recent years. Looking for new cathode materials with high electrocatalytic activity and robust stability at relatively low temperatures is one of the essential requirements for intermediate-to-low-temperature SOFCs (ILT-SOFCs). During the past 15 years, we put considerable efforts into the development of alternative cathode materials for ILT-SOFCs. In this review, we give a summary of our progress from such efforts. We first summarize several strategies that have been adopted for developing cathode materials with high activity and durability toward reducing operating temperatures of SOFCs. Then, our new ideas and progress on cathode development with respect to activity and stability are provided. Both the cathodes of oxygen-ion-conducting SOFCs and protonic-conducting SOFCs are discussed. In the end, we outline the opportunities, challenges, and future approaches for the development of cathodes for ILT-SOFCs.
