Inkjet manufacturing of CCMs for PEMFC by development of catalyst inks & their deposition - IMMENSE
In the course of global undertakings to achieve a CO2-neutral energy economy, the German-Spanish-Czech consortium of the project named IMMENSE targets the UN sustainable development goals (SDG) 7 and 9. In detail, it plans to make impact on the current fuel cell technology by tailoring the catalytic ink and processing it using digital inkjet-printing technology supplementing the currently used analogous processes. The consortium represents experts for material development focussing on tuning interfacial properties. In focus are a flexible design of CCMs, reducing manufacturing costs, experimental characterization and advanced mathematical modelling. A short stack fuel cell demonstrator will validate the new manufacturing technology based on an optimized material system that shows similar performance as conventionally produced fuel cells used for mobile applications.
- Inkjet-printed CCMs perform better than state-of-the art ultrasonic sprayed onesat significantly lower Pt loading
- Synthesized bio-based ionomers present good and temperature stable ionicconductivity
- Microwave synthesis of Pt/C catalysts are basis for core shell catalyst development
- Newly developed materials show performance comparable to commercial ones
- Simulation of catalyst distribution generates better understanding for processes
- Project results meet industrial target performance parameters
