Abstract:	La_0.6Sr_1.4MnO₄ (LSMO₄) layered perovskite with K₂NiF₄ structure was prepared and evaluated as anode material for La_0.8Sr_0.2Ga_0.83Mg_0.17O_3 − δ (LSGM) electrolyte supported intermediate temperature solid oxide fuel cells (IT-SOFCs). X-ray diffraction results show that LSMO₄ is redox stability. Thermal expansion coefficient of LSMO₄ is close to that of LSGM electrolyte. By adopting LSMO₄ as anode and La_0.6Sr_0.4Co_0.8Fe_0.2O₃ (LSCF) as cathode, maxium power densities of 146.6, 110.9 mW cm^− 2 with H₂ fuel at 850, 800 °C and 47.3 mW cm^− 2 with CH₄ fuel at 800 °C were obtained, respectively. Further, the cell demonstrated a reasonably stable performance under 180 mA cm^− 2 for over 40 h with H₂ fuel at 800 °C.
