La 0.4 Sr 0.5 Ba 0.1 TiO 3 (LSBT) is a promising anode candidate with perovskite structure, due to its excellent chemical stability even in sour hydrocarbons. Infiltrating nano‐composite catalysts into the perovskite substrate can further enhance the electrochemical activity without undermining the robustness of the anode in light hydrocarbon fuels. This paper focuses on developing a new LSBT anode with enhanced catalytic performance and chemical stability in syngas and hydrogen fuel by infiltrating the substrate with Cu+Co and CeO 2 +Cu+Co nano‐composite catalysts. It was found that CeO 2 +Cu+Co significantly improved the chemical and thermal stabilities of the anode. However, an excess of infiltration reduced the active sites. The SOFC cell with the LSBT anode, which was infiltrated with 9.0 wt.% CeO 2 + 3.6 wt.% Cu + 5.4 wt.% Co, exhibited much improved electrochemical performance in syngas environments.
