A micro-model for the calculation of the area specific resistance ASRcat of a porous mixed ionic electronic conducting (MIEC) cathode, which resolves the microstructure, has been presented in Part I of this article. Four processes are considered relevant for a parametric study of this solid oxide fuel cell (SOFC) model. These comprise a charge transfer process between the electrode and the electrolyte and three noncharge transfer processes in the porous electrode: (i) gas diffusion, (ii) bulk diffusion and (iii) surface reaction. In Part II we present a systematic parameter sensitivity analysis of the four parameters that describe these processes. We define an index called sensitivity factor that allows the quantitative determination of the importance of the different processes for a reconstructed 3D microstructure.
