Perovskite Sr2Fe1.5Mo0.5O6-delta (SFM) demonstrates excellent redox stability and shows remarkable electrical conductivity of 550 S cm(-1) in air and 310 S cm(-1) in hydrogen at 780 degrees C. SFM has been applied as both anode and cathode in symmetrical SOFCs using LSGM as the electrolyte, achieving a peak power density over 835 mW cm(-2) at 900 degrees C using H-2 as fuel and ambient air as oxidant.
