Analysis of triple phase contact in Ni–YSZ microstructures using non-destructive X-ray tomography with synchrotron radiation

This is the authors' abstract. We don't add key points for this paper.

Here, we demonstrate the use of X-ray absorption edge spectroscopy in conjunction with high resolution X-ray nano-computed tomography to provide a comprehensive microstructural map of a Ni–YSZ electrode from a Solid Oxide Fuel Cell. The experimentally derived microstructure has been used to develop a geometrical test for microstructural homogeneity.
