Summary
Yttria fully stabilized zirconia (YSZ) thin films have been used as an electrolyte in solid oxide fuel cells. The microstructural characteristics of the thin films has played an important role in controlling efficiency and reliability of the fuel cell. Experimental studies have shown that both the grain size and the film texture highly depends on various fabrication and processing parameters. To explore an optimal processing technique for maximizing the performance and durability of the fuel cell, a stochastic grain growth model is developed by implementing Thompson's grain evolution law into a probabilistic computational framework. The resulting stochastic grain size evolution model can be used to trace both the microstructure and texture subjected to a given processing condition.
