High performance electrochemical systems (e.g. electrodes for solid oxide fuel cells, gas separation membranes and batteries) have microstructural requirements that require using graded, hierarchical and/or anisotropic porous materials. A multi-scale modelling framework for sintering analyses is utilized for the description of the experimentally observed evolution of the pore orientation in textured porous structures. The meso-scale level of the sintering simulations assumes a bi-porous material structure in accord with the characteristics of the materials utilized in the experiments. The evolutions of both the meso-scale domains and the macroscopic volume of the analyzed porous material are modelled by the finite-element method. The presentation describes the differences between the small and large pore evolution based on the specifics of viscous and diffusional mass transport during sintering processes.
