Modeling of a microstructure and calculation of a tortuosity factor for cathodic materials of LSM–YSZ

A. S. Farlenkov, M. V. Anan’ev

Abstract


In this work changes in physico-chemical properties (oxygen interphase exchange rate and specific resistance) and microstructure parameters (TPB length and tortuosity factor) with time have been analyzed to find the quantitative relationships on the example of composite cathode material LSM-YSZ. 3D microstructure of LSM-YSZ materials has been reconstructed and tortuosity factor has been calculated on the basis of SEM image analysis using the original software.

Keywords


composite material; speed of interfacial oxygen exchange; tortuosity factor
