Research and development of next generation polymer electrolyte fuel cells has intensified as it is viewed as a key technology in the decarbonization of heavy-duty transportation. Current polymer electrolyte fuel cell design suffers from drawbacks that hinder wide-spread commercialization in these sectors. Especially, improved catalyst layers with lower amounts of costly platinum group metals, improved mass transport characteristics at high current densities and increased durability are required.
To tackle these challenges, our research will focus on developing novel synthetic methods enabling local control of ionomer coating in the catalyst layer. New (fluorine-free) ionomer chemistries will be explored and applied using these techniques to impart optimal wettability, ionic conductivity, and gas permeability to enhance electrode performance. The materials will be thoroughly characterized and compared against state-of-the-art materials for performance and durability in a membrane electrode assembly (MEA) configuration.
