【摘要】：采用相转化流延一步制备了NiO-Zr0.84Y0.16O2-d(YSZ)阳极支撑层和功能层,前者厚度为~700mm,含有沿厚度方向定向排列的开放直孔,后者厚度为~60mm。采用浆料涂膜法和高温共烧在阳极上制备厚度为15mm的YSZ电解质薄膜,丝网印刷制备YSZ-La0.84Sr0.16MnO3-d(LSM)(质量比50:50)阴极。所制备的单电池显示出较高的电输出性能。以H2-3%H2O为燃料和环境空气为氧化剂,800℃时电池的峰功率密度达到891mW/cm2,电池即使在高电流密度测试条件下也未出现明显的浓差极化,这是由于其阳极具有开放直孔结构,气相输运阻力小。
[Abstract]:NiO-Zr0.84Y0.16O2-dYSZ) anodic support layer and functional layer were prepared by a one-step phase conversion flow process. The former has a thickness of 700 mm and contains an open straight hole arranged in a directional direction along the thickness of NiO-Zr0.84Y0.16O2-dYSZ. The thickness of the latter is 60 mm. The YSZ electrolyte film with a thickness of 15 mm was prepared on the anode by slurry coating and high temperature co-firing. The cathode of YSZ-La0.84Sr0.16MnO3-dn / LSMU (mass ratio 50: 50) was prepared by screen printing. The single cell showed high electrical output performance. The peak power density of the cell reached 891 MW / cm ~ 2 even at high current density using H _ 2-3H _ 2O as fuel and ambient air as oxidant at 800 鈩，
