摘　　要：使用浆料旋涂法制备了致密氧化钇稳定的氧化锆电解质薄膜,进而组装成阳极支撑型单气室固体氧化物燃料电池.该电池在CH4,N2和O2混合气氛下运行,可产生很高的输出性能.在700℃时开路电压达到1 V,最大功率密度达到398 mW/cm2.在开路状态下,电池的欧姆电阻为0.097Ω.cm2,仅为电极阻抗的6.4%,远小于电极极化电阻.通过优化电极材料,阳极支撑型单气室固体氧化物燃料电池将具有更优异的输出性能和更广阔的应用前景.An anode-supported single-chamber solid oxide fuel cell （SC-SOFC） with dense yttria-stabilized zirconia film as the electrolyte was fabricated by the slurry spin coating technique. The single cell exhibited high performance when operated in a mixture of methane, nitrogen, and oxygen. At 700℃ , the open current voltage and maximum power density were 1 V and 398 mW/cm^2, respectively. The ohmic resistance was as small as 0.097 Ω·cm^2, being 6.4% of the electrode polarization resistance only. Therefore, the anode-supported SC- SOFC with optimized electrode materials is very promising.
