| Zusammenfassung: | The performance of a solid oxide fuel cell (SOFC) is strongly affected by electrode polarization losses, which are related to the composition and the microstructure of the porous materials. A model that can decouple the effects associated with the geometrical arrangement, shape, and size of the particles together with material distribution on one side and the material properties on the other can give a relevant improvement in the understanding of the underlying processes. A porous mixed ionic-electronic conducting (MIEC) cathode was reconstructed by focused ion beam tomography. The detailed geometry of the microstructure is used for 3D calculations of the electrochemical processes in the electrode and to calibrate a well-established reduced model obtained by averaging. We perform a model-based estimation of the parameters describing the main processes and estimate their confidence regions using the calibrated reduced model. |
