Notes:
Under SOFCs operating condition, the cathode reaction rate is determined by triple phaseboundary (TPB) areas which are associated with the geometry of the interface between the cathodeand the electrolyte. In this paper, YSZ electrolyte was deposited by atmospheric plasma spraying(APS). A nano-scaled lanthanum strontium manganate (LSM) cathode was prepared by sol-gelprocess on APS YSZ with different surface roughness to aim at increasing the TPB. The polarizationcurves of LSM cathode were characterized by potentiostat. The influence of the roughness of APSYSZ on the polarization of LSM cathode was investigated. It was found that the overpotential of theLSM cathode is significantly reduced with the increase of YSZ surface roughness
