Ni-BSCZGY composites with volume ratio of 30:70, 40:60, and 50:50 were synthesised through mechanical mixing and combustion methods. In combustion method, auto-ignition step led to brown coloured ash, which was calcined at 1000 oC for 5 h to form NiO-BSCZGY powder. Screen-printing, co-firing and reduction process were used to prepare the symmetrical cell: Ni-BSCZGY/BSCZGY/Ni-BSCZGY. Ni50-BSCZGY anode exhibited the lowest polarisation resistance (Rp) of 0.8 Omega.cm2 and 1.9 Omega.cm2 at 710 oC under 3% H2O-H2, for both mechanically mixed and combustion methods, respectively.enUnless otherwise indicated, this material is protected by copyright and has been made available with authorization from the copyright owner.
