Ni content was reduced to 2 vol%, and nanosized Ni particles were uniformly dispersed in a mixed ionic-electronic conducting matrix comprising gadoliniumdoped ceria (GDC) using a thin-film technique. Remarkable stability with no performance deterioration even after 100 reduction-oxidation cycles could be observed for the optimized nanostructured anodes. Cell performance at 500 degrees C was enhanced, exceeding 650 mW/cm(2). This study offers valuable insights for enhancing the durability, performance, and productivity of SOFCs.
