Influence of Sintering Temperature on the Structural, Morphological, and Electrochemical Properties of NiO-YSZ Anode Synthesized by the Autocombustion Route

In this study, nickel oxide–Y2O3-doped ZrO2 (NiO-YSZ) composite powder as an anode material was synthesized using a cost-effective combustion method for high-temperature solid oxide fuel cell (SOFC). Further, the effects of sintering temperatures (1200, 1300, and 1400 °C) were studied its properties in relation to SOFC performance. The prepared sintered NiO-YSZ materials characterized their surface morphology, composition, structure, conductivity. cubic crystalline nature NiO YSZ sufficed by X-ray diffraction, SEM images revealed increase densification microstructure temperature. EDX spectrum confirmed presence nickel, yttrium, zirconia without any impurity. Conductivity measurements, under hydrogen environment, that NiO-YSZ, at °C, exhibits better conductivity compared samples lower temperatures. Electrochemical performance button-cells also evaluated peak power density 0.62 Wcm−2 is observed 800 °C. citrate provided cells containing 1200 which previously reported higher Therefore, found be suitable route synthesize low
