摘要：In the present work, Nano Composite Anodeswere synthesized as X (NiO) +1-X (Ce0.8Gd0.2O2-δ)where(X = 30& 40 wt. %) for low temperature operating solid oxide fuel cells (SOFC). The NiO synthesized by solgelcitrate method and Thermal analysis of TG/DTG carried out up to 800 oC of the dried precursor of NiO andalso calcined from 600 oC to750 oC. For anode materials, NiO and GDC20 nano powders were mechanically mixedand pelletized, sampleswere sintered at 1300oC . Systematic study of structure, purity, phase and structural parametersof as-synthesized NiO and anode samples were carried out by XRD and SEM. The A.C conductivity and theiractivation energies of the Anode sample (compositions X = 30& 40 wt.%)were computed from RT to 500 oC with theimpedance data and the conductivities are found 1.30x10-3 S/cm and 2.53 x10-3 S/cmrespectively at 500 oC (frequency1.33MHz) .The activation energies of A.C conductivity have observed that decrease with increase in frequencies.
