摘要:

 采用流延法制备以ScSZ为电解质的电解质支撑电池、以LSM/ScSZ为电池阴极材料,用浸渍的方法制备优化后的钙钛矿La0.9Ca0.1Fe0.9Nb0.1O3–δ (LCFNb10)阳极。结果表明:Nb的加入有利于钙钛矿材料在氢气中的稳定性,且最佳掺杂量为10% (摩尔分数)时,LCFNb10电池在氢气、一氧化碳和丙烷中的放电功率在850 ℃分别可达526.7、452.3、328.1 mW/cm2,表明LCFNb10是一种极具前景的SOFC电池阳极材料。

 La0.9Ca0.1Fe1–xNbxO3–δ (LCFNb10) perovskite for SOFCs anode was prepared by a citrate-nitrate route and impregnation method to form nano-scaled LCFNb10 anode catalytic layer. Based on the analysis by X-ray diffraction, LCFNb10 anode is rather stable in H2 at high temperatures. The single cells with LCFNb10 impregnated anode both achieve a high power output with maximum power densities (MPDs) being 526.7, 452.3 and 328.1 mW/cm2 in H2, CO and C3H8 at 850 ℃, respectively, indicating that LCFNb10 has a promising potential to use as SOFCs anode.
