主 题：Cr-poisoning perovskite infiltration solid oxide fuel cell LaNi0.6Fe0.4O3-δ
摘 要：LaNi（0.6）Fe（0.4）O（3-δ） （LNF） powders were synthesized by the glycine-nitrate process and LNF-gadolinium-doped ceria （GDC） nanocomposite cathodes for solid oxide fuel cells （SOFCs） were fabricated by infiltration from LNF porous backbones. Electrochemical properties and Cr-poisoning behavior of LNF-GDC cathodes were studied. Single phase perovskite LNF could be obtained at the glycine to nitrate molar ratio of 1：1. The polarization resistance of the LNF-GDC nanocomposite cathode was significantly decreased in comparison with the LNF. This phenomenon was associated with enhanced catalytic activity and enlarged triple-phase boundary （TPB） length by GDC nano particles. In addition, the nanocomposite cathode showed good Cr tolerance under open circuit condition. The LNF-GDC nanocomposite cathodes were expected for use as a potential cathode in intermediate- temperature solid oxide fuel cells （IT-SOFC）.
