  "abstract": "Proton exchange membrane fuel cells (PEMFCs) are highly efficient devices for converting chemical energy into electrical energy. At present, however, their large-scale implementation is primarily hindered by the limited lifetime of the membrane electrode assembly (MEA), which typically utilizes perfluorinated ionomers, such as Nafion™. Current research focuses on incorporating radical scavenging species into the MEA to enhance durability. This work investigates the use of functionalized CeO 2 nanoparticles coupled with Aquivion®, a short-sidechain ionomer that outperforms state-of-the-art Nafion™. The novelty lies in the application of organosilanes bearing fluorinated chains as grafting agents on the CeO 2 surface to improve filler-polymer compatibility. The most promising nanocomposites exhibit uniform filler dispersion, and a 50% reduction in both swelling ratio and ex-situ fluoride ions emission rate, while maintaining conductivity values above 150 mS cm -1 at 80°C and 100% RH. Furthermore, fuel cell performance comparable to, or exceeding, pristine Aquivion® was observed, with negligible degradation after >650 h of accelerated stress testing. These findings could pave the way for a new generation of composite membranes featuring polymer-tailored scavenger functionalization.",
