Proton exchange membrane (PEM) fuel cells (FCs) as zero CO₂ emitting power sources are among the most promising technologies for achieving carbon neutrality and meeting carbon reduction targets. However, the technical indicators for transportation power sources set by the EU with the ultimate goal of becoming the first climate-neutral continent by 2050 are hard to achieve using current FC technologies. The performance, durability, weight, and price depend heavily on the FC key components, such as electrocatalysts, membrane-electrode assemblies (MEAs), and bipolar/flow field plates (BPPs). Therefore, this proposal will develop an integrated solution for the next-generation components of PEMFCs toward achieving EU targets. The highly complementary consortium, bringing together experts in materials science, electrochemistry, engineering, and system integration, will ensure a multidisciplinary, innovative approach to accomplish the main goal of the proposal.
