Objectives
- Description of the catalyst coated layer (CCL, membrane or other substrate) structure and transport properties and mechanisms at its different scales
- Characterization of the local conditions in the CCL during operation
- Establishment of the link between structure / properties of CCL, local conditions during operation, and performance
- Propose and validate structure and composition of CCL with improved catalyst efficiency and durability
