为提高镍-氧化钇稳定氧化锆(Ni-YSZ)阳极支撑的固体氧化物燃料电池(SOFC)以含碳气为燃料时的抗积碳性能,采用丝网印刷法在Ni-YSZ阳极表面印制阻挡层,阻挡层的材料为高温煅烧制备的铁酸锰(MnFe_2O_4)粉体。在750 ℃下以模拟污泥微波热解生物质气为燃料,测试含阻挡层的电池的电化学效能和抗积碳性能,并利用扫描电镜对测试前、后的阳极进行表征。研究结果表明:MnFe_2O_4阻挡层与Ni-YSZ 阳极的结合性较好;在Ni-YSZ 阳极上添加MnFe_2O_4阻挡层后,电池的放电性能有所降低,但是电池在以模拟生物质气为燃料时的抗积碳性能大幅提高,且在浆料中添加16%(质量分数)的石墨制备的阻挡层效果最佳。本研究对Ni-Y...

In order to improve carbon deposition resistance of nickel/yttria stabilized zirconia (Ni-YSZ) anode-supported solid oxide fuel cell (SOFC) in carbon-containing fuels, barrier layer was prepared on the Ni-YSZ anode by screen printing in this research. The barrier layer material was spinel manganese ferrite (MnFe2O4), which was produced by high-temperature calcination. The cell with barrier layer and the blank cell were tested in simulated biosygas at 750 ℃ to compare efficiency and carbon deposition resistance. The anodes were characterized by...
