Title: Evaluation of a surface treatment on the performance of Crofer 22 APU in a SOFC Button Cell

Abstract

Crofer 22 APU is a 22 weight percent Cr ferritic stainless steel developed at Forschugszentrum Jülich and manufactured by ThysennKrupp for application as an interconnect in SOFC. We have developed a cerium oxide surface treatment which greatly enhances the oxidation resistance of this and many other alloys. Minimizing scale growth is helpful for improving the performance in interconnect application; however, the overall performance is dependant upon such things as scale thickness, scale resistivity, etc. We report on the in-cell performance of cerium treated and conventional Crofer 22 APU and discuss the results in terms of the microstructure and scales that form.
