Microstructure evolution driven by thermal coarsening is an important factor for degradation of SOFC electrode. In this work, the effect of the initial microstructure on the microstructure evolution in SOFC electrode is investigated using a recently developed phase field model. Specifically, we tune the average grain size, broadening of the grain size distribution and the shape of the grains in the initial microstructure, and explore the evolution of the grain size, the specific surface area and the density of triple phase boundary in Ni-YSZ anode and LSM-YSZ cathode. And the conductivity change due to the microstructure evolution in both electrodes is studied as well. A map between the properties of the initial microstructure and the evolution rate of the properties in SOFC has been established, and an optimal initial microstructure is identified and discussed.
