چکیده انگلیسی
The new phase inversion tape casting method is explored to fabricate the “porous|dense|porous” La0.9Sr0.1Ga0.8Mg0.2O3 (LSGM) with aligned straight pores. Symmetrical fuel cells are obtained by impregnating nano-scale SrFe0.75Mo0.25O3-δ (SFMO) catalysts into both porous LSGM scaffolds. Operation on hydrogen and air oxidants produces 401, 521, 602 and 703 mW cmâ2 at 650, 700, 750 and 800 °C, respectively. Impedance measurements show that the overall interfacial polarization resistances are 0.17, 0.20, 0.25 and 0.36 Ω cm2 for such symmetrical fuel cells at 800, 750, 700 and 650 °C, respectively. Impedance analysis under varied oxygen partial pressures indicates that the symmetrical SFMO-LSGM electrodes exhibit lower polarization resistances for phase-inversion casted LSGM scaffolds than for the traditionally casted LSGM scaffolds.
