| Abstract: | 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 20 mΩ cm2 at 750 °C when the composite contains 8 wt% Pd, and it could be comparable to pure Pt. The ohmic resistance of a single cell using LSM-Pd composite is about 255 mΩ cm2 that contains 4 wt% Pd as current collector, this value is close to that of a cell using expensive Pt paste as current collector. |
