Perovskite Sr2Fe1.5Mo0.5O6 – δ (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 °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 °C using H2 as fuel and ambient air as oxidant.
