Electrochemical performance and anode reaction process for Ca doped Sr2Fe1·5Mo0·5O6-δ as electrodes for symmetrical solid oxide fuel cells

Ca doped Sr2Fe1·5Mo0·5O6-δ (SFM) is investigated as a novel electrode for symmetrical solid oxide fuel cells. CaxSr2-xFe1.5Mo0.5O6-δ (Cax-SFM) maintains the perovskite phase under both oxidizing and reducing atmospheres when the doping content x ≤ 0.50. The Ca doping significantly improves the condu...
