英文摘要A series of composite cathodes with various YSZ additions;were investigated by AC impedance, polarization and conductivity measurement. The electrochemical performance of the cathodes was improved by increasing the YSZ addition, and the optimal YSZ addition for the lowest electrode resistance (1.18 Omega/ cm(2)) was found to be 40%. The rate-determining step of the cathode reaction varied when YSZ was added into the LSM electrode. The contact resistance increased as YSZ addition increased. By applying a layer of platinum on the cathode as a current collecting layer, the contact resistance decreased significantly , and the electrode resistance at 1223 K dropped remarkably from 1.18 Omega /cm(2) to 0.41 Omega /cm(2).
