文摘
- •
Properties of Nafion membranes with co-cast CeO2, ZrO2 or YSZ were analyzed.
- •
Considerable build-up of iron was detected in conventional Fenton’s test.
- •
Membranes with co-cast Fe2+ were degraded by exposure to aqueous H2O2.
- •
Nafion/CeO2 membranes showed, in all cases, less signs of degradation.
