| Project Detail |
PEM water electrolysers (PEMWE) and PEM fuel cell (PEMFC) technologies currently rely on perfluorinated sulfonic acid (PFSA)-based materials and components, which pose significant health and environmental risks due to the release of toxic fluorine groups during production and disposal. Moreover, the production of PFSA remains costly, compounding the challenges associated with their use. Therefore, the ECOPEM project aims at developing safe-by-design, non-fluorinated hydrocarbon-based membranes, reinforcements, and ionomers. This ambitious work will be facilitated by the development and implementation of life cycle thinking tools addressing environmental and economic dimensions to drive the research and innovation using quantifiable sustainability criteria. ECOPEM will deliver scientific breakthroughs in the design and processing of materials, components and membrane electrode assembles (MEAs) enabling replacement of PFSAs by hydrocarbon-based polymers in membranes and catalyst layers. The project will validate the significant benefits of these MEAs by demonstrating an increased current density, reaching a minimum of 3 A cm-2 at a cell voltage of 1.8 V and degradation rate < 5µV/h for PEMWE cells; and a power density > 1.5 W/cm2 at 0.650 V and a degradation rate < 5 µV/h for PEMFC using harmonized JRC testing procedures. Achieving these ambitious targets would result in a new standard for hydrocarbon-based MEAs for PEMWE and PEMFC applications. |
