A novel cathode material, La(Ni0.4Fe0.6)O-3 (LNF), is synthesized by a solid-state reaction for applications in solid oxide fuel cells (SOFCs). The electrochemical performance of the LNF cathode is investigated for the oxygen reduction reaction at 900 degrees C in the presence of a Fe-Cr alloy interconnect, and compared with (La,Sr)MnO3 (LSM) cathodes. Under these conditions, the LNF electrode has a more stable electrochemical activity than that of the LSM electrode. There is no deposition of chromium species on the electrode surface or at the LNF electrode/yttria-stabilized zirconia (YSZ) electrolyte interface after passage of 200 mA cm(-2) for 20h at 900 degrees C. By contrast, a significant amount of chromium species is preferentially deposited at the LSM/YSZ interface regions for the LSM electrode. The results demonstrate that the LNF electrode has high tolerance to chromium poisoning, and is, therefore, promising as a SOFC cathode when using chromia-forming alloy interconnects.
