The CNTFSM made from Pt/SWNT at a loading of 0.082 mg Pt cm–2 exhibits higher performance with a peak power density of 0.675 W cm–2 in comparison with a commercially available E-TEK electrocatalyst made of Pt supported on XC-72 carbon black, which had a peak power density of 0.395 W cm–2 at a loading of 0.084 mg Pt cm–2 also without Nafion in the catalyst layer.enCarbon nanotubeCatalysisProton exchange membrane fuel cellElectrocatalystNafionChemical engineeringMaterials scienceMembraneCarbon fibersLayer (electronics)article
