Abstract EN
In this work, Yttria (Y2O3) was successfully doped into tetragonal 3mol% yttria stabilized Zirconia (3YSZ) by high energy-mechanical milling tosynthesize 8mol% yttria stabilized Zirconia (8YSZ) used as an electrolytefor high temperature solid oxide fuel cells (HT-SOFC).
This work aims toevaluate the densification and ionic conductivity of the sinteredelectrolytes at 1650°C.
The bulk density was measured according to ASTMC373-17.
The powder morphology and the microstructure of the sinteredelectrolytes were analyzed via Field Emission Scanning ElectronMicroscopy (FESEM).
The chemical analysis was obtained with Energydispersive X-ray spectroscopy (EDS).
Also, X-ray diffraction (XRD) wasused to obtain structural information of the starting materials and thesintered electrolytes.
The ionic conductivity was obtained throughelectrochemical impedance spectroscopy (EIS) in the air as a function oftemperatures at a frequency range of 100(mHz)-100(kHz).
It is found thatthe 3YSZ has a higher density than the 8YSZ.
The impedance analysisshowed that the ionic conductivity of the prepared 8YSZ at 800°C is0.
906 (S.
cm) and it was 0.
214 (S.
cm) of the 3YSZ.
Besides, 8YSZ has a loweractivation energy 0.
774 (eV) than that of the 3YSZ 0.
901(eV).
Thus, theprepared 8YSZ can be nominated as an electrolyte for the HT-SOFC.
