Abstract

The plasma coatings are applied to the surface of a commercial fuel cell catalyst (20% Pt on Vulcan XC-72) with a tumbling RF-plasma reactor. The use of plasma thin film chemistries with proton conducting potential such as hexafluropropylene oxide with sulfur dioxide (HFPO-SO2) and vinyl phosphonic acid (H3PO4) are shown to enhance the limiting current density of PEM fuel cells over control samples. Other plasma treatments such as oxygen show no effect on the MEA performance. The paper will describe the plasma treatment processes, chemical analysis, MEA fabrication, and fuel cell performance testing.
