Investigation Of Nano-Ceria Catalyst Infiltration Of Solid Oxide Fuel Cell (Sofc) Electrodes Using Bio-Inspired Catechol Surfactants, Ozcan Ozmen
Graduate Theses, Dissertations, and Problem Reports
Development of solid oxide fuel cell (SOFC) electrodes with nano-structured grains can show enhanced power density with high catalytic activity owing to the higher surface area to volume ratio of the particles. However, the addition of nano-particles during the conventional electrode manufacturing process causes inevitable structural changes due to the coarsening of nano-particles at sintering temperatures. Wet impregnation/ infiltration methods are a practical and well-utilized method to form nanoparticles within the porous electrode microstructure of solid oxide fuel cells (SOFC) which requires relatively low calcination temperatures. Critical factors that impact the reduction of the electrode polarization using the nano-catalyst impregnation …
