SYNTHESIS OF LAxSR1-xTIO3 ANODE MATERIALS BY SOL-GEL AUTO-COMBUSTION METHOD

A novel anode material for intermediate temperature solid oxide fuel cells with a composite of La xSR1-xTiO3 has been synthesized by a sol-gel auto-combustion method. X-ray diffraction (XRD) shows that La xSR1-xTiO3 has good chemical compatibility with Gd0.2 Ce0.8O1.9 electrolyte. The thermal expans...
