Infiltrated Nanofiber-Based Nanostructured Electrodes for Solid Oxide Fuel Cells

The feasibility and opportunity of nanostructured defect-engineered electrodes for exceptional performance stability solid oxide fuel cells operating at intermediate temperatures (500–700°C) are reported in this study. electrode is designed with infiltrated La0.4Sr0.6MnO3-δ (LSM) nanoparticles as oxygen reduction reaction catalysts on an yttria-stabilized zirconia (YSZ) nanofiber scaffold a controlled sintering temperature 800–1200°C optimized nanostructures defect concentration the scaffold. Nanostructured lowest 800°C exhibits ~8.1 times higher specific surface area ~1.6 vacancy than that 1200°C. cell demonstrates outstanding ~2.11 1.09 W/cm2 700 600°C, respectively, excellent 300 h under current density 1.5 A/cm2 750°C.
