Abstract

Solid oxide cells (SOCs) are emerging devices for efficient energy storage and conversion. However, during SOC operation, gaseous chromium (Cr) species released from Fe-Cr alloy interconnect can lead to Cr deposition and poisoning of air electrodes, causing substantial degradation in electrochemical performance and compromising the long-term stability of SOCs. This mini-review examines the mechanism of Cr deposition and poisoning in air electrodes under both fuel-cell and electrolysis modes. Furthermore, emphasis is placed on the recent advancements in strategies to mitigate Cr poisoning, offering insights into the rational design and development of active and Cr-tolerant air electrodes for SOCs.

固体氧化物电池耐铬空气电极的研究进展

固体氧化物电池（soc）是新兴的高效能量存储和转换器件。然而，在SOC工作过程中，从Fe-Cr合金互连中释放的气态铬（Cr）物质会导致Cr沉积和空气电极中毒，导致电化学性能严重下降，影响SOC的长期稳定性。本文综述了燃料电池和电解两种模式下空气电极中Cr沉积和中毒的机理。此外，重点放在减轻Cr中毒策略的最新进展，为soc活性和耐Cr空气电极的合理设计和开发提供见解。

期刊介绍： Journal of Fuel Chemistry and Technology (Ranliao Huaxue Xuebao) is a Chinese Academy of Sciences(CAS) journal started in 1956, sponsored by the Chinese Chemical Society and the Institute of Coal Chemistry, Chinese Academy of Sciences(CAS). The journal is published bimonthly by Science Press in China and widely distributed in about 20 countries. Journal of Fuel Chemistry and Technology publishes reports of both basic and applied research in the chemistry and chemical engineering of many energy sources, including that involved in the nature, processing and utilization of coal, petroleum, oil shale, natural gas, biomass and synfuels, as well as related subjects of increasing interest such as C1 chemistry, pollutions control and new catalytic materials. Types of publications include original research articles, short communications, research notes and reviews. Both domestic and international contributors are welcome. Manuscripts written in Chinese or English will be accepted. Additional English titles, abstracts and key words should be included in Chinese manuscripts. All manuscripts are subject to critical review by the editorial committee, which is composed of about 10 foreign and 50 Chinese experts in fuel science. Journal of Fuel Chemistry and Technology has been a source of primary research work in fuel chemistry as a Chinese core scientific periodical.
