摘　　要：金属连接体作为固体氧化物电池(Solid oxide cells, SOCs)的核心组件,在工作温度范围内会发生严重的氧化和高价铬挥发导致阴极Cr中毒,从而降低电池性能与寿命。在金属连接体表面添加锰钴尖晶石涂层是防止其失效的有效手段,但是锰钴涂层存在电导率低、烧结致密度差的问题。本文综述了近年来SOCs金属连接体防护用锰钴涂层的制备方法、成分设计对电导率、热膨胀系数、抗氧化性能等的影响。稀土元素与过渡金属元素的共同掺杂可以协同调控锰钴尖晶石涂层的电导率和抗氧化性能。此外,对锰钴涂层的设计、制备技术和性能改进提出了未来发展方向。As the key component of solid oxide cells(SOCs),the metallic interconnector experiences serious oxidation and highvalence chromium volatilization,resulting in the Cr poisoning on the cathode and degradation of cell performance.Manganese cobalt spinel coating on the surfaces of metal interconnectors is an effective strategy to prevent their failure;however,these coatings also have problems,such as relatively low conductivity and poor sintering density.This article reviews the effect of preparation methods and composition design of manganese cobalt coatings on the conductivity,thermal expansion coefficient,and oxidation resistance of SOCs metal interconnectors in recent years.The results indicate that the codoping of rare earth and transition metal elements can synergistically regulate the conductivity and oxidation resistance of manganese cobalt spinel coatings.Finally,we provide future development directions for the design,preparation technology,and performance improvement of manganese cobalt coatings.
