研究了LSM-Pd复合材料作为SOFC阴极集电体在(La0.8Sr0.2)0.9MnO_3(LSM90)阴极上的电化学性能。研究了Pd含量对接触电阻的影响。研究表明，当Pd含量为8wt%时，LSM-Pd在750C时的接触电阻约为20MΩcm2，与纯铂相当。含4wt%Pd作为集电体的单电池的欧姆电阻约为255MΩcm2，接近于使用昂贵的铂膏作为集电体的电池的欧姆电阻。
The electrochemical performance of LSM–Pd composite material as current collector of SOFC cathode is studied on (La0.8Sr0.2)0.9MnO3(LSM90) cathode. The influence of Pd content on contact resistance is investigated. The investigation shows that the contact resistance of LSM–Pd is about 20mΩcm2at 750°C when the composite contains 8wt% Pd, and it could be comparable to pure Pt. The ohmic resistance of a single cell using LSM–Pd composite is about 255mΩcm2that contains 4wt% Pd as current collector, this value is close to that of a cell using expensive Pt paste as current collector.
