Is 2D stereological method good enough for quantification of solid oxide fuel cell electrode microstructure?

Modeling of solid oxide fuel cells

“…However, the FIB-SEM technique is expensive and time-consuming. A 2D stereological method is thus developed by Zhang et al [9] to estimate the 3D geometric properties of SOFC electrodes. The 2D method can be used to analyze the electrode porosity, volume fractions of solid phases, inner surface/interface area, and TPB length with good agreement with the 3D results.…”

“…To this point, twodimensional (2D) stereological methods have been employed to quantify electrode geometric characteristics. 15,16 However, this method is limited to the isotropic microstructures, and incapable of determining tortuosity factors and the percolated portions of the phase networks, surfaces, interfaces, and TPBs. Over the past decade, X-ray nanotomography (XNT) and focused ion-beam serial sectioning-scanning electron microscopy (FIB-SEM) have been employed to image the three-dimensional (3D) microstructures of SOFC electrodes.…”
