![]() By controlling the drying process during the infiltration process, two distinct nano-structures of SSC, discrete coating and film-like coating, were fabricated on the GDC scaffolds. ![]() We systematically designed a nano-structured cathode functional layer (CFL) from the infiltration of Sm 0.5Sr 0.5CoO 3− δ (SSC) into porous Gd 0.2Ce 0.8O 2− δ (GDC). ![]() Here, we demonstrate rational design of infiltrated nano-structures for IT-SOFCs with enhanced ORR kinetics and excellent stability. Nano-structured composite electrodes, from a carefully conducted infiltration process, are one of the most promising electrode structures for intermediate temperature solid oxide fuel cells (IT-SOFCs), due to their ability to promote the oxygen reduction reaction (ORR) and enlarge triple phase boundaries (TPBs).
