摘要：A precursor to SOFC anode was made via solution combustion technique that is NiO-GDC (Gadolinia dopedCeria) composites by mixing nitrates of cerium, gadolinium and nickel in stoichiometric ratio of composition to formthe final precursor product as Ce0.90Gd0.10O1.95 - 0.40 NiO. The fuel for the combustion synthesis that is glycine’sconcentration was varied between 0.5 mole% to 1.4 mole%. The temperature of the resultant sintered pellets was variedbetween 30 to 800ºC and electrical properties of the NiO-CGO composite was studied by means of admittance plotsbetween conductivity & susceptance. The results showed that the composite precursor varied in conductivity andactivation energy depending on the concentration of the fuel.
