Abstract
Sm0.5Sr0.5CoO3?? (SSC) infiltrated Ce0.9Gd0.1O2?? (GDC) composite cathodes are developed for protonic ceramic fuel cells (PCFCs). Although the \SSC\ infiltrated \GDC\ cathodes make little contribute to expending the reaction sites of water formation, it can significantly improve the oxygen reduction dynamics among the whole electrochemical reaction. The symmetric half cell and single cell testing results demonstrate the high electrochemical activity of \SSC\ infiltrated \GDC\ cathodes. Moreover, the single cell is stable at 600
