Application of a composite structure of carbon nanoparticles and Nb-TiO2 nanofibers as electrocatalyst support for PEM fuel cells

► Deposited Pt nanoparticles on a mixed support of Nb-doped TiO2 nanofibers and carbon agglomerates. ► Characterized catalytic properties of the materials electrochemically and physically. ► Compared properties to a commercially available carbon supported Pt catalyst. ► Measured fuel cell performance with the synthesized materials as electrodes.
