A ferrite-based perovskite oxide La0.5Sr0.5Fe0.9Mo0.1O3-delta (LSFMo) has been evaluated as the anode of intermediate-temperature solid oxide fuel cell (IT-SOFC). XRD result indicates that no metallic iron precipitates from the lattice when the LSFMo was reduced under reducing atmosphere. The LSFMo exhibits a n-type semiconducting behavior in dry H-2 and its conductivity values attain 2.5-6.8 S cm(-1) at 600-850 degrees C. The polarization resistances (R-p) of LSFMo anode on La0.9Sr0.1Ga0.8Mg0.2O3-delta (LSGM) electrolyte are 9.08 cm(2) at 700 degrees C and 3.04 Omega cm(2) at 800 degrees C in dry H-2 under open-circuit condition; however, with introducing a Sm0.2Ce0.8O2-delta (SDC) interlayer between the anode and electrolyte, the R-p values are decreased to 1.54 Omega cm(2) at 700 degrees C and 0.50 Omega cm(2) at 800 degrees C. The maximum power densities (P-max) of the LSGM supported single cell with configuration of LSFMo/SDC/LSGM/ Ba0.6Sr0.4Co0.9Nb0.1O3-delta achieve 722 mW cm(-2) in H-2 and 513 mW cm(-2) in CH4 at 800 degrees C. Moreover, good power cycle stability of the cell in CH4 means excellent carbon resistance of the LSFMo anode. The high electrochemical performance indicates that the LSFMo is a promising anode material for using in IT-SOFC. (C) 2017 Elsevier Ltd. All rights reserved.
