AB Nanocomposites exhibit improved electrochemical and mechanical properties compared to single-phase mate-rials, making them promising for the development of efficient and durable electrodes in solid oxide fuel cells(SOFCs). However, conventional fabrication methods usually involve multiple steps and high sintering tem-peratures, potentially leading to adverse effects on the properties of these materials due to excessive grain growthor reactivity among the cell components. In this study, nanocomposite electrodes of Sm0.5Sr0.5CoO3-δ -Ce0.9Sm0.1O1.95 (SSC–CSO) are prepared using a co-synthesis freeze-drying method, followed by screen-printingdeposition and sintering at high temperatures. Alternatively, they are prepared through direct spray-pyrolysisdeposition on the electrolyte at reduced temperatures. In both cases, the intimate mixture of SSC and CSOphases not only partially suppresses grain growth but also provides extended actives sites for the electrochemical
