采用溶液浸渍法制备了用于中温固体氧化物燃料电池（it - sofc）的纳米结构和钯促进的sr掺杂LaMnO3 （LSM）基阴极。与传统的LSM/ y2o3掺杂ZrO2 YSZ复合阴极相比，纳米结构和pd促进的LSM基阴极的电化学性能都有显著提高，在600℃时电极极化电阻分别为1.5和0.9 ω cm(2)，而传统的LSM/YSZ阴极的极化电阻为70 ω cm(2)。开发的阴极也获得了较低的活化能，这表明这种纳米结构和pd促进电极作为中温sofc的阴极具有良好的适用性。(C) 2008电化学学会。[DOI: 10.1149/1.2987693]版权所有。
Nanostructured and palladium-promoted Sr-doped LaMnO3 (LSM)-based cathodes are developed via solution impregnation for intermediate-temperature solid oxide fuel cells (IT-SOFCs). Both the nanostructured and Pd-promoted LSM-based cathodes show significantly improved electrochemical performance compared to the conventional LSM/Y2O3-doped ZrO2 YSZ composite cathode, with electrode polarization resistances of 1.5 and 0.9 Omega cm(2) at 600 degrees C, respectively, in contrast to 70 Omega cm(2) obtained from the conventional LSM/YSZ cathode. Low activation energies are also obtained with the developed cathodes, indicating a promising applicability of such nanostructured and Pd-promoted electrodes as cathodes for the intermediate-temperature SOFCs.
