Fabrication and evaluation of Nafion nanocomposite membrane based on ZrO2-TiO2 binary nanoparticles as fuel cell MEA

► Recast Nafion composite membrane with ZrO2-TiO2 nanoparticles binary oxides investigated. ► The membrane was tested in a 25 cm2 single cell at the temperature range of 40-110 °C. ► The MEA with Nafion/TiO2-ZrO2 presented highest PEM fuel cell performance. ► Mechanistic of the binary nanocomposite membrane systems as fuel cell MEA were discussed.
