High-Temperature Electrolysis Capabilities

Transmission x-ray tomography (TXM-synchrotron) generates 3D tomography of samples removed from cells, via laserFIB, ion FIB, or plasma FIB, providing structural and chemical information at 30 nm resolution. Imaging at the absorption edge of specific elements provides element specific information (i.e., the Ni, YSZ, and pore structure can each be isolated in the fuel electrode and information such as the triple phase boundary percolating network calculated). X-ray absorption spectra collected at each 30 nm pixel/voxel provides chemical information such as oxidation states and enables 2D or 3D chemical maps to be collected. Nano-CT (lab-scale) also provides 30-nm resolution. Element specific information is gained by segmenting voxels based on adsorption coefficient enabling similar information to be collected as with the TXM (the technique is single energy so XAS data collection is not possible). Micro-CT provides 3D structural information on the micron-scale. Atomic force microscopy provides dynamic 3D topographic imaging of surfaces under environmental control with atomic to microscale resolution.
