Solid oxide fuel cells (SOFCs) are solid-state environmentally friendly power generation devices with high energy conversion efficiency. Their commercialization has been affected by long-term stability problems. In recent years, to solve the long-term stability problems of traditional Ni-based cermet anodes, increasing attention has been given to oxide ceramic anodes due to their excellent impurity poisoning resistance, carbon deposition resistance and excellent structural stability in both oxidizing and reducing atmospheres. In addition, the cathode material of SOFCs is also composed of oxide ceramic materials with high conductivity and good catalytic activity for the oxygen reduction reaction (ORR). However, there are some problems, such as interface reactions or the interdiffusion of elements between oxide electrodes and oxide electrolytes at high temperature, which are the key issues affecting the long-term stability of SOFCs. In recent years, many studies have proposed relevant mechanisms and solutions. For example, in perovskite oxide materials with ABO₃ structures, the elemental ratio of A/B and cation deficiency at A-sites and B-sites can significantly affect the high temperature chemical compatibility between the oxide electrodes and electrolytes. In this review, the interface compatibility between oxide electrodes and ceramic electrolytes in SOFCs, interfacial reactions, interdiffusion and corresponding suppression mechanisms are reviewed.

固态氧化物燃料电池（SOFC）是具有高能量转换效率的固态环保型发电设备。它们的商业化已受到长期稳定性问题的影响。近年来，为了解决传统的镍基金属陶瓷阳极的长期稳定性问题，由于氧化物陶瓷阳极具有优异的抗杂质中毒性，抗碳沉积性以及在氧化和还原性气氛中均具有优异的结构稳定性，因此越来越引起人们的关注。 。另外，SOFC的阴极材料也由具有高电导率和对氧还原反应（ORR）的良好催化活性的氧化物陶瓷材料组成。但是，有一些问题，例如高温下的界面反应或元素在氧化物电极和氧化物电解质之间的相互扩散，这是影响SOFC长期稳定性的关键问题。近年来，许多研究提出了相关的机制和解决方案。例如，在具有ABO的钙钛矿氧化物材料中_在3种结构中，A-位和B-位的A / B元素比和阳离子缺乏会显着影响氧化物电极和电解质之间的高温化学相容性。本文综述了SOFC中氧化物电极与陶瓷电解质之间的界面相容性，界面反应，相互扩散及相应的抑制机理。
