Gadolinium-doped ceria is an attractive electrolyte material for potential application in SOFCs operating at intermediate temperature typically with 10-20 % substitution of Ce+4 by Gd+3. Nanometric powders of Gadolinium-doped ceria have been prepared by hydrothermal treatment both with conventional method and with microwave-assisted method using co-precipitate as a precursor and in the presence of simply deionized water as a mineralizer.

Abstract

Gadolinium-doped ceria is an attractive electrolyte material for potential application in SOFCs operating at intermediate temperature typically with 10-20 % substitution of Ce+4 by Gd+3. Nanometric powders of Gadolinium-doped ceria have been prepared by hydrothermal treatment both with conventional method and with microwave-assisted method using co-precipitate as a precursor and in the presence of simply deionized water as a mineralizer. The obtained powders have been characterized by XRD, TEM, SEM and DTA-TG. Adopting an optimized sintering cycle very dense ceramics based on hydrothermally synthesized gadolinium-doped ceria have been obtained
