ExpectedOutcome:Green hydrogen is routinely cited as a major pillar of the clean energy transition by the European Commission, where fuel cell and electrolyser technologies are expected to play an important role in achieving Europe's emissions reduction targets. Proton exchange membrane (PEM)-based fuel cells (PEMFCs) and electrolysers (PEMELs) are currently among the most mature technologies, dominating both current capacity and expected near-term growth. Currently, all PEM-based hydrogen technologies rely on perfluorinated sulfonic acid (PFSA)-based ionomers combined with a membrane reinforcement made from expanded polytetrafluorethylene (ePTFE) and contain polytetrafluoroethylene (PTFE) in other functional layers such as the gas diffusion layer (GDL). These fluoropolymer PFSA and ePTFE components have exceptional chemical stability and durability, as well as high ionic conductivity and favourable wetting properties for optimal water balance. Together, these properties enable high performance PEMFC/PEMEL operation over extended lifetimes.
