Ultra Small Angle X-ray Scattering Studies of Solid Oxide Fuel Cell Cathode Powders

摘要

We demonstrate the feasibility of using Ultra Small Angle X-ray scattering to study cathode structures in solid oxide fuel cells (SOFC) under operating conditions. Cathode thickness has been optimized and test symmetric SOFC structures have been characterized. We also demonstrate that we can following the evolution of microstructure on a LSCF infiltrated YSZ backbone structure under annealing conditioning, showing the viability of characterizing multi-scale cathode structures in real time.
