摘要： 以吡啶为分散剂,采用真空注浆法制备出膜厚为0.2mm、长度为140mm的致密YSZ电解质膜管。研究了烧结温度对样品致密度和离子导电率的影响.用1650℃烧结2h制备的致密YSZ电解质膜管组装成固体氧化物燃料电池,以氢气和煤气为燃料,研究了电池在500～900℃的电化学性能.实验结果表明,用真空注浆法可制备出高质量和高密度的YSZ电解质膜管,在1600℃烧结后,其相对密度已达到理论密度的98.1%,接近理论密度.单电池的开路电压最大值为1.213V,最大输出功率为0.48W.以氢气为燃料的燃料电池性能明显高于以煤气为燃料的电池性能.

Abstract: The dense yittria-stabilized zirconia membrane tube was prepared by using pyridine as dispersant by vacuum casting.The thickness of the membrane in the tube is 0.2 mm and the length is 140 mm.The effect of sintering temperature on the density and ionic conductivity of the samples was studied.The solid oxide fuel cell(SOFC) was made of the YSZmembrane tube, which was sintered at 1650 for 2 h.The electrochemical property of the SOFCwas studied from 500 to 900,hydrogen and city coal gas were used as fuel, respectively.The research shows that the YSZmembrane tube with a high quality and density can be prepared by the vacuum casting, the relative density of the YSZmembrane tube reaches 98.1% of theoretical density at sintering temperature of 1600,approaching the theoretical density.The maximum of open voltage is 1.213 V, and the maximum of output power is 0.48 W.The electrical property of the SOFCwith hydrogen as fuel is superior to that of the one with city coal gas as fuel.
