Plasma deposited Pt-containing hydrocarbon thin films as electrocatalysts for PEM fuel cell

Author affiliations

Abstract

High performance electrocatalytic hydrocarbon thin films containing Pt nano-clusters are deposited by simultaneous plasma polymerization of ethylene and sputtering of a Pt target. The proposed synthetic approach largely simplifies the PEMFC electrocatalyst fabrication process with respect to conventional methods. The deposition of the hydrocarbon matrix provides the mechanical support and electronic continuity, ensuring a uniform metal dispersion, avoiding Pt nanoparticle agglomeration. The Pt catalyst is dispersed as small vertically stacked clusters with size less than 10 nm in columnar thin (250–500 nm) films. PEMFC testing with plasma deposited 500 nm thick film and 0.513 mg cm−2 Pt load as anodic electrocatalyst led to a maximum reproducible power density as high as 300 mW cm−2.
