New strategies for overcoming the chemical degradation of anion-exchange membranes (AEM) containing perfluoroquaternary ammonium (PFQA) ionomer using inorganic free radical scavengers are described. To be more specific, the metal-oxide-perfluorinated sulfonic acid ionomer (MO-PFSA) composite nanoparticles were synthesized and investigated their nano-redispersibility after redispersing in the PFQA solution. The effect of the PFSA equivalent weight (EW) and metal precursor selection, and nano-redispersibility of MOx composite nanoparticles in the PFQA solution were also investigated. It was reported that MOx composite nanoparticles prepared using cerium nitrate precursor showed the best radical scavenging performance in the presence of EW800 PFSA solution compared to other MO-PFSA composite nanoparticles.Graphical abstract Mechanism of nano-redispersion of the metal-oxide-perfluorinated sulfonic acid ionomer (MO-PFSA) composite nanopowders in perfluoroquaternary ammonium (PFQA) solution
