A modified spray pyrolysis approach has been utilized to fabricate anode electrode of a Solid Oxide Fuel Cell (SOFC). It was designed to control the anode microstructure to achieve large triple phase boundaries (TPBs) and high gas diffusion capability, which are critical in enhancing the performance of a SOFC. Deposition of porous anode film of Nickel and Ce0.9Gd0.1O1.95 on dense 8 mol.% yttria stabilized zirconia (YSZ) substrate was carried out using the modified spray pyrolysis. Effects of precursor solution feed rates, precursor solution concentrations and deposition temperatures on the TPB formation and porosity were investigated. The composition of the deposited anode film was evaluated by energy dispersive X-ray spectroscopy (EDS). Scanning electron microscope (SEM) examinations revealed that the deposition temperature and precursor solution concentration were the most critical parameters that influenced the morphology, porosity and the particle size of the anode film.
