摘要 使用浸渍法制备具有纳米催化粒子的固体氧化物燃料电池电极可以提高电池性能。结合静电喷雾技术以及浸渍法制备的Sm0.2Ce0.8O2-δ(SDC)La0.6Sr0.4Co0.2Fe0.8O3-δ(LSCF)浸渍阴极。对于静电喷雾技术中沉积温度对于薄膜形貌的影响做了讨论。阻抗谱研究表明,以300℃下沉积制得的薄膜为骨架的阴极具有最小的极化阻抗,在650、700、750、800℃分别为0.484、0.077、0.034、0.022Ω.cm2。以这种电极为阴极并以稳定的氧化锆为电解质的单电池在750℃时最大功率密度为254mW/cm。 Electrode of solid oxide fuel cell(SOFC) with nano-size catalytic particles prepared by impregnation technique can improve the performance of the cell.Sm0.2Ce0.8O2-δ(SDC) and La0.6Sr0.4Co0.2Fe0.8O3-δ(LSCF)composite cathode was fabricated by combining the electrostatic spray deposition(ESD) and infiltration technique.Influence of deposition temperature on the morphology of deposited film was discussed by ESD technique.Cathode prepared with backbones deposited at 300℃ showed the lowest polarization resistance,650℃ 0.484Ω·cm2,700℃ 0.077Ω·cm2,750℃ 0.034Ω·cm2 and 800℃ 0.022Ω·cm2.Anode-support cells with the infiltrated cathode and zirconia-based electrolytes showed peak power den sities of 254mW/cm at 750℃.
