Abstract

The efficacy of CeO₂ naroparticles in mitigating free radical induced PEM degradation in investigated. Commercially obtained CeO₂ and nanoparticles synthesized in-house were incorporated within a recast Nafion® membrane. MEAs were prepared using Nafion® and Nafion® -CeO₂ composite membranes (0.5wt%, 1wt%, and 3wt% CeO₂). The composite membranes exhibited very similar proton conductivities (∼35mS/cm) and hydrogen crossover (∼1 mA/cm²) as Nafion®. However, the fluoride emission rate (estimated from accelerated tests) was lowered by more than one order of magnitude upon addition of CeO₂ into the Nafion® membrane, suggesting that CeO₂ nanoparticles have potential to enhance membrane durability.
