Investigation of Cu-based infiltration coatings for metal-supported SOFC
Paper in proceedings, 2013

Metal-supported solid oxide fuel cells are candidates for the next generation of SOFCs. However, the cell design with an FeCr/YSZ-based anode backbone suffers from corrosion when the cells are run at high fuel utilization, which limits the long term durability. In this work, new infiltration coatings based on Cu in combination with Ni:Ce0.8Gd0.2O 1.9 (Ni:CGO) have been studied. The candidates for a corrosion resistant coating should limit the formation of Cr2O3 on the surface of FeCr particles. Promising fuel cell performance with an ASR of 0.5 Ωcm2 was obtained at 650 °C with H2 as fuel. However, various analysis techniques showed no improved corrosion resistance with the addition of a Cu coating.
