Abstract
In this study, solid oxide fuel cells short stack was tested. After a long-term operation, the subsequent microstructural analysis was conducted using a combination of the focused ion beam and scanning electron microscopy. The method allows obtaining a set of two-dimensional images from different cross-sections that are then reconstructed into the three-dimensional virtual model of the microstructure. Based on that model the microstructure parameters were quantified. The microstructural studies were conducted at nine different locations and also for a supplementary sample called the reference cell. The reference cell did not participate in the aging test, and microstructure analysis was conducted at an as-received cell. The obtained results indicate that the microstructure morphology evolution has a heterogeneous character. It was shown that multiple changes in microstructure morphology could cause overlapping degradation and optimization effects that could lead to the improvement of the stack performance. © ECOS 2019 - Proceedings of the 32nd International Conference on Efficiency, Cost, Optimization, Simulation and Environmental Impact of Energy Systems.
