随着固体氧化物燃料电池(SOFC)工作温度降低到600℃-800℃，传统的陶瓷互连线被用高抗氧化性的金属合金取代。在可制造性、成本、机械强度和导电性方面，金属互连比陶瓷互连更具优势。到目前为止，有希望用于金属互连的候选材料都是含铬合金，它们很容易发生挥发性铬迁移，导致电池退化。因此，保护性涂层已经被开发出来，以有效地抑制铬的迁移，同时保持良好的导电性和良好的抗氧化性。本文综述了金属互连发展的进展和技术挑战，以及中温SOFC应用中金属互连的不同类型的保护涂层和沉积技术。(C)2016年氢能源出版有限责任公司。爱思唯尔有限公司出版。保留所有权利。
With the reduction of solid oxide fuel cells (SOFCs) operating temperature to the range of 600 degrees C-800 degrees C, metallic alloy with high oxidation resistance are used to replace traditional ceramic interconnects. Metallic interconnects is advantageous over ceramic interconnects; in terms of manufacturability, cost, mechanical strength, and electrical conductivity. To date, promising candidates for metallic interconnects are all Cr-containing alloys, which are susceptible to volatile Cr migration that causes cell degradation. As such, protective coatings have been developed to effectively inhibit Cr migration; as well as maintain excellent electrical conductivity and good oxidation resistance. This article reviews the progress and technical challenges in developing metallic interconnects; different types of protective coatings and deposition techniques for metallic interconnects for intermediate temperature SOFC applications.
