چکیده انگلیسی
In this study, anode supported intermediate temperature micro-tubular solid oxide fuel cells (MT-SOFCs) have been fabricated by combination of phase-inversion, dip-coating, co-sintering and printing method. The MT-SOFC consists of a â¼300 μm wall-thickness Ni-Sc2O3 stabilized ZrO2 (ScSZ) anode tube, â¼10 μm ScSZ dense electrolyte layer, â¼10 μm Ce0.9Gd0.1O2âδ (GDC) membrane buffer layer and â¼50 μm Ba0.9Co0.7Fe0.2Nb0.1O3âδ (BCFN) cathode layer. SEM and electrochemical impedance spectroscopy (EIS) analysis suggested that the novel structured anode can remarkably diminish the porous anode geometrical tortuosity and improve the fuel gas diffusivity. High peak power densities of 0.34, 0.51 and 0.72 W cmâ2 have been achieved with humidified hydrogen as the fuel and ambient air as oxidant at 550, 600 and 650 °C, respectively. Further, the cell has demonstrated a very stable performance with no significant cell voltage degradation under a constant current of 0.6 A cmâ2 for over 213 h test at 650 °C.
