XRD and EDS Analysis of Composite Cathode Powders LSCF-SDCC-Ag for Low Temperature Solid Oxide Fuel Cells (LTSOFC)

Abstract

X-ray diffraction (XRD) and energy dispersion spectroscopy (EDS) analysis has been conducted on composite cathode powder LSCF-SDCC-Ag. Composite cathode powder LSCF-SDCC has been produced using high energy ball milling via wet milling method through calcinations at 750 °C. The calcined LSCF-SDCC powder then was mixed with Ag (3wt%) then pressed become pellets and sintered at 500, 550 and 600 °C. The phase purity of composite cathode powder LSCF-SDCC-Ag was determined via XRD analysis and elements distributions were observed via EDS-mapping. The SrCO3 phase was emerged after the addition of composite cathode powder LSCF-SDCC with Ag powder. The phase purity of composite cathode powder LSCF-SDCC-Ag were maintained before and after sintered. The variable of sintering temperature also not effect the structure as there were no other secondary constituent emerged as confirmed by XRD sensitivity. EDS analysis shows LSCF-SDCC-Ag produced via ball milling has uniform distribution of elements.
