摘要：
This study details long-term performance data for anode-supported thin-film YSZ-based SOFCs utilizing a ferritic stainless steel cathode current collector (Crofer22 APU) coated with a protective (Mn,CO)(3)O(4) spinel to prevent Cr volatilization. Two standard cathode compositions, La(Sr)FeO(3) and La(Sr)MnO(3), were considered. The coating proved effective in blocking Cr migration, which resulted in long-term stability of the manganite cathode. In contrast the ferrite cathode indicated degradation that could not be attributed to Cr poisoning.
