Thin film deposition for oxygen ionic conduction layer of solid oxide fuel cell by pulsed-laser deposition (PLD) technique
EMSL Project ID
49881
Abstract
In order to prevent the unwanted chemical reactions of conventional yttrium stabilized zirconia (YSZ) electrolytes of solid oxide fuel cells (SOFCs) with lanthanum strontium cobalt ferrite (LSCF) cathodes and to optimize the electrolyte thickness for enhanced cell performance and stability, thin films deposited using PLD will be developed for application as solid oxide fuel cell electrolytes. Both YSZ electrolyte and samarium doped ceria (SDC) barrier layer will be deposited with different thicknesses on anode supported cells. Scanning electron microscopy (SEM) and x-ray photoelectron spectroscopy (XPS) techniques will be employed to confirm the densification and oxidation states of these thin films. Electrochemical tests will be conducted on cells employing these layers to study their effects on cell performance and stability.
