摘要
固体氧化物燃料电池工作温度的降低,使铁素体不锈钢用作连接体成为了可能。这类连接体具有热导率高、导电性能好、热膨胀性匹配等优点,但也存在一些问题,如高价Cr的挥发以及抗氧化性弱等。涂层可以改善铁素体不锈钢的相关性能。本文综述了稀土氧化物涂层、钙钛矿涂层以及尖晶石涂层的涂层类型和涂覆方法,比较了在金属连接体中的应用效果。
Ferritic Stainless Steels（FSS） can be applied as interconnects of solid oxide fuel cells at reduced operating temperatures due to their high thermo conductivities, suitable coefficients of thermal expansion and low price. However, practical application is still facing various challenges, such as low oxidation resistances and high volatility of chromium oxides. These issues could be minimized by coating technique. In this review, the application and effects of rare element oxide coatings（REOs）, perovskite coatings and spinel coatings were compared and discussed.
