An amphiphilic-like fluoroalkyl modified SiO2 nanoparticle@Nafion proton exchange membrane with excellent fuel cell performance

Abstract

A new route to enhance the cell performance of a Nafion proton exchange membrane is provided by incorporating fluoroalkyl modified SiO₂ nanoparticles. In favor of the achieved amphiphilic-like surface characteristics of SiO₂ nanoparticles, the so-formed nanocomposite membrane exhibited great enhancement of single cell performance at 80 °C: ∼34% increase in output power relative to the Nafion reference and a superior maximum output power as high as 579.6 mW cm⁻².
