Combustion Synthesis of Nanoparticles CeO2 and Ce0.9Gd0.1O1.95
Ceria and Gd2O3 doped ceria nanoparticle powder has been fabricated using a combustion synthesis method for an application as an electrolyte for Intermediate Temperaure Solid Oxide Fuel Cell (ITSOFC). The nanoparticle powder is obtained when the processing parameters are optimized. Three different fuels i.e. urea, citric acid and glycine have been used for producing the nanoparticle powder of doped ceria. The produced particles have been characterized using SEM for the particle morphology, XRD for phase identification, and particle analysis for the particle size distribution and identification. In addition, these particles have shown good reforming activity, which provide an opportunity for this material not to be used only as an electrolyte but also as a support for the anode part of SOFC.
