Nondestructive Reconstruction and Analysis of SOFC Anodes Using X-ray Computed Tomography at Sub-50 nm Resolution
John R. Izzo,Abhijit S. Joshi,Kyle N. Grew,Wilson K. S. Chiu,Andrei Tkachuk,Siew H. Wang,Wenbing Yun +6 more
TL;DR: In this article, a high-resolution, non-destructive X-ray computed tomography (XCT) technique is applied to image the three-dimensional (3D) microstructure of a solid oxide fuel cell (SOFC) composed of a liquid yttria-stabilized zirconia electrolyte and a porous nickel YSZ (Ni-YSZ) anode.
Journal ArticleDOI
Nondestructive Nanoscale 3D Elemental Mapping and Analysis of a Solid Oxide Fuel Cell Anode
Kyle N. Grew,Yong S. Chu,Jae-mock Yi,Aldo A. Peracchio,John R. Izzo,Yeukuang Hwu,Francesco De Carlo,Wilson K. S. Chiu +7 more
TL;DR: In this article, a tomographic imaging technique at 38.5 nm spatial resolution was used along with numerical models to examine the phase and pore networks within an SOFC anode and provide insight into the heterogeneous microstructure's contributions to the origins of transport-related losses.
Journal ArticleDOI
Three-dimensional microstructural changes in the Ni-YSZ solid oxide fuel cell anode during operation

TL;DR: In this article, microstructural evolution in solid oxide fuel cell (SOFC) cermet anodes has been investigated using X-ray nanotomography along with differential absorption imaging.
Journal ArticleDOI
Comparison of SOFC cathode microstructure quantified using X-ray nanotomography and focused ion beam scanning electron microscopy
George J. Nelson,William M. Harris,Jeffrey J. Lombardo,John R. Izzo,Wilson K. S. Chiu,Pietro Tanasini,Marco Cantoni,Jan Van herle,Christos Comninellis,Joy C. Andrews,Yijin Liu,Piero Pianetta,Yong S. Chu +12 more
TL;DR: In this article, X-ray nanotomography and focused ion beam scanning electron microscopy (FIB-SEM) have been applied to investigate the complex 3D microstructure of solid oxide fuel cell (SOFC) electrodes at spatial resolutions of 45 nm and below.
Journal ArticleDOI
Three-dimensional mapping of nickel oxidation states using full field x-ray absorption near edge structure nanotomography
George J. Nelson,William M. Harris,John R. Izzo,Kyle N. Grew,Wilson K. S. Chiu,Yong S. Chu,Jae-mock Yi,Joy C. Andrews,Yijin Liu,Piero Pianetta +9 more
TL;DR: In this article, X-ray nanotomography combined with x-ray absorption near edge structure (XANES) spectroscopy has been applied to study samples containing distinct regions of nickel and nickel oxide (NiO) compositions.
