Abstract

Carbon nanotube/nanofiber papers (i.e., buckypapers) supported Pt catalysts were synthesized using a supercritical fluid deposition method for proton exchange membrane fuel cell (PEMFC) applications. The process involves impregnating buckypapers with plantinum precursor PtMe₂COD (dimethyl (cyclooctadiene) platinum(II)) in supercritical CO₂ fluid and thermally reducing PtMe₂COD in N₂ at 200C. Highly dispersed fine platinum (Pt) particles were obtained on the buckypaper support resulting in a high electrochemical surface area (ECSA) of 100 m²/g. With an ultralow Pt loading of 25 g/cm² in Pt/buckypaper cathode catalyst layer, cell performance reached as high as 400 mW/cm² at 0.65 V and 830 mW/cm² at peak.
