Abstract

The use of dual-beam focused ion beam-scanning electron microscopy to make a complete three-dimensional reconstruction of a solid-oxide fuel-cell electrode was investigated. The dual-beam focused ion beam-scanning electron microscopy greatly facilitated the process to obtain volumetric information that can be integrated to provide 3D information for 3D microstructure reconstruction, by providing high-quality volumetric data. It was shown that 3D reconstruction can be used for quantifying and understanding the performance of fuel-cell electrodes. It was found that 3D reconstruction can be used to make quantitative correlations between processing and mirostrcture. It was reported that the information obtained from 3D reconstruction can be used to track microstructural changes during long-term fuel-cell operation, providing important information regarding fuel-cell stability.
