FIB Tomography Scanning
Electrolyte supported nickel and yttria-stabilised zirconia (Ni-YSZ) symmetrical cells were manufactured using screen printing, with half cells then chemically reduced and characterised using electrochemical impedance spectroscopy. After electrochemical testing, the samples were scanned using FIB tomography (Zeiss xB-1540 FIB-FEG SEM, London Centre for Nanotechnology) to characterise the Ni-YSZ electrode microstructure. 170 images with pixel dimensions of 20 nm were created with an inter-slice thickness of 15 nm. 100 images were selected and segmented for further analysis.
