The effect of cerium ions (Ce3+) on the anti-oxidation and other properties of sulfonated poly(ether ether ketone) (sPEEK) membrane was studied, as it quenches the hydroxyl radicals, the major oxidation promoter in fuel cell operation. Cerium (Ce) was introduced along with 15-crown-5-ether to form a coordination complex to prevent both the migration of Ce3+ ions from the membranes and the direct interaction with sulfonic acid groups in sPEEK. The chemical and physical structures of the composite membranes were investigated using FT-IR, 1H NMR, SEM, EDX, and SAXS. |
