Multi-scale imaging and simulation
The deepest secrets of fuel cell catalyst layers in 3D
- A number of advanced structural characterization techniques have been developed in Prof. Jankovic team.
- Techniques are applicable to fuel cells, electrolyzers, batteries (with some further development).
- Advanced quantification of STEM-EDX maps was developed to provide important parameters in BOL and EOL samples: Pt loading, I/C ratio, CL porosity, OER catalyst agglomerate size distribution, Pt and Ionomer profiles etc.
- The technique provides important information about degradation effects on catalyst laters
- Capability in ionomer imaging in catalyst inks and layers (2D and 3D)
- 3D imaging, reconstruction and simulation of catalyst layers, MPL and GDLs have been demonstrated
- A number of correlations with performance of CL properties has been established
- Great potential of using these techniques to provide understanding of FC performance and degradation and input into mathematical models
- Potential for improved CL design and choice of materials
