Possible Repair Mechanism for Hydrocarbon-Based Ionomers Following Damage by Radical Attack

Polymer electrolyte fuel cell (PEFC) membranes are subject to radical-induced degradation. Antioxidant strategies for hydrocarbon-based ionomers containing aromatic units can focus on intermediates that are formed upon attack by hydroxyl radicals (HO · ). Among the different intermediates, the catio...
