Modeling of Ni-CGO anode in a solid oxide fuel cell deposited by spray pyrolysis

► A complete electrode polarization model of a SOFC has been developed. ► Model incorporated electrode microstructural parameters into cell performance. ► Model agreed within 10% of the EIS results for different anode microstructures. ► Homogeneous anode optimal particle size decreased with increasing anode porosity. ► Cell optimization should balance electrochemical aspect and structural reliability.
