Solid oxide cells (SOCs) are highly efficient and versatile devices capable of utilizing a variety of fuels, presenting promising solutions for energy conversion and renewable resource utilization. There is an urgent need for the strategic design of robust and high-efficiency materials to enhance both conversion and energy efficiencies before SOCs can be applied for large-scale industrial production. Nanocomposite electrodes, especially those fabricated through infiltration and metal nanoparticle exsolution, have emerged as highly active electrocatalytic materials that significantly improve the performance and durability of SOCs. This review systematically summarizes and analyzes recent advances in the nanoscale architecture of electrode materials fabricated via common nanoengineering strategies, including infiltration and in situ exsolution, with applications in CO/HO reduction, hydrocarbon electrochemical oxidation, solid oxide fuel cells, and reversible operation. Finally, this review highlights existing bottlenecks and promising breakthroughs in common nanotechnologies, aiming to provide useful references for the rational design of nanomaterials for SOCs.
固体氧化物电池（SOCs）是高效且通用的装置，能够利用多种燃料，为能量转换和可再生资源利用提供了有前景的解决方案。在SOCs可应用于大规模工业生产之前，迫切需要对坚固且高效的材料进行战略设计，以提高转换效率和能量效率。纳米复合电极，尤其是通过浸渍和金属纳米颗粒析出制备的电极，已成为高活性电催化材料，可显著提高SOCs的性能和耐久性。本文综述系统地总结和分析了通过常见纳米工程策略（包括浸渍和原位析出）制备的电极材料在纳米级结构方面的最新进展，这些材料应用于CO/H₂O还原、烃类电化学氧化、固体氧化物燃料电池以及可逆运行。最后，本文综述突出了常见纳米技术中存在的瓶颈和有前景的突破点，旨在为合理设计用于SOCs的纳米材料提供有用的参考。
