制备了管状固体氧化物燃料电池，并对其微观结构和电化学性能进行了评价。通过将NiO-Y2 O3稳定的ZrO 2（YSZ）浆料浇铸在塑料模具（管）的内壁上来制备管状基底。壁厚和均匀性由浆料粘度和管的旋转速度控制。电池由Ni-YSZ功能阳极、YSZ电解质和（La0.8Sr0.2）0.95MnO3-δ（LSM）-YSZ阴极组成。它们的尺寸为长50 mm，厚0.8 mm，外径10.5 mm。 在650 ° C和850°C之间的温度下，电池的峰值功率密度在85至522 mW cm-2的范围内，并且通过将PdO浸渍到LSM-YSZ阴极中而大大提高到308至1220 mW cm-2的范围。 在0.7 A cm-2和750°C下282 h的电池测试期间，浸渍的PdO颗粒通过聚结生长，这增加了阴极极化电阻，从而降低了电池性能。 根据退化趋势，电池性能将在较长的运行中稳定。
Tubular solid oxide fuel cells were fabricated and evaluated for their microstructure and electrochemical performance. The tubular substrate was prepared by casting NiO-Y2O3 stabilized ZrO2 (YSZ) slurry on the inner wall of a plastic mold (tube). The wall thickness and uniformity were controlled by slurry viscosity and rotation speed of the tube. The cells consisted of Ni-YSZ functional anode, YSZ electrolyte and (La0.8Sr0.2)0.95MnO3-δ (LSM)-YSZ cathode prepared in sequence on the substrate by dip-coating and sintering. Their dimension was 50 mm in length, 0.8 mm in thickness and 10.5 mm in outside diameter. The peak power density of the cell at temperatures between 650 and 850°C was in the range from 85 to 522 mW cm−2 and was greatly enhanced to the range from 308 to 1220 mW cm−2 by impregnating PdO into LSM-YSZ cathode. During a cell testing at 0.7 A cm−2 and 750°C for 282 h, the impregnated PdO particles grew by coalescence, which increased the cathode polarization resistance and so that decreased the cell performance. According to the degradation tendency, the cell performance will be stabilized in a longer run.
