Project description

The project aims to explore the complementarity of information obtained with SAXS and coherent X-ray imaging on fuel cell electrode materials. Fuel cell electrode materials are porous nanomaterials with structural features across multiple length scales. The goal within this project is to provide a non-invasive structural characterization of porous nanocomposite materials on the meso- and nanoscale in order to gain insights on the structure performance relation in fuel cell electrode materials. The project is set up in a close collaboration between the SAXS beamlines at MAXIV (ForMAX and CoSAXS) and the corresponding cSAXS beamline at the Swiss Light Source at PSI. It includes method transfer of SAXS imaging in 2D and 3D transfer from PSI where it is well established to the beamlines at MAXIV.
