4M Research – of fundamental nature and technological orientation
• ORR kinetics and electrolyte modifications - Kinetics, Acid Adsorption, Catalysis
• Synergies between durable supports and catalysts- Alternative non-carbon supports
• Initiatives towards non-precious metal catalysts- Composites Me-Nx/C type- Exploration of novel structures and materials
• Anhydrous conductivity and proton functionalities- acid-base chemistry versus protonics- immobilization of doping functionalities
• Electrodes, MEA and single cell testing
- understanding, fabrication, performance, durability
• Fuelling strategies and impact on lifetime- other hydrogen carriers (e.g. methanol)
• Stack engineering- design and construction
• Diagnostics, simulation and system management- single cell, stack and system
