Efficient and controlled nano-catalyst solid-oxide fuel cell electrode infiltration with poly-norepinephrine surface modification

There is a growing attention to enhance the performance of solid oxide fuel cell (SOFC) electrodes through incorporation nano-catalyst materials within electrodes’ active sites. In this study, we report technique for increased efficiency and microstructural control infiltration process polymerized norepinephrine (pNE) treatment. Nano-CeO2 catalysts were incorporated both commercial anode-supported SOFCs using single salt solution step after coating pNE porous microstructure. The optimization catalyst loading was performed by varying cerium nitrate concentrations between 0.4 2.0 M. ceria nanoparticles are distributed at near-electrolyte region in electrodes, but with variance due precursor molarity loading. time-dependent polarization resistance (Rp) variation categorized into three zones Zone I referred baseline low-catalyst fluctuating Rp. However, cells II III showed continuous activation as low 0.275 ? cm2 750 °C. results suggest that nano-CeO2 film reduces coarsening related degradation backbone. addition, pNE-assisted dip enhanced infiltrant deposition reducing number steps.
