Development of fuel cell electrodes by plasma processing

Abstract : This work is part of a collaborative program between the GREMI laboratory in France (Orléans) and SP3 group in ANU (Canberra) on fuel cell optimization by plasma processing. My research project has involved developing a highly efficient fuel cell electrode made of high specific area carbon nanostructures surrounded by platinum catalyst by plasma techniques. During the first phase in France, I focused on platinum nanoparticles soaking of a chemical porous uncatalysed electrode over a depth of few hundred nanometers by plasma sputtering. This method decreased the platinum loading which is very expensive, compared to traditional chemical electrodes without decreasing the fuel cell efficiency. I started the second phase of my PhD in July 2005 at the Plasma Research Laboratory of the Australian National University. The plan for the Australian component of my research was to deposit high surface area carbon supports for the fuel cell catalyst by using plasma processing techniques. In this new electrode morphology, the catalyst is dispersed on few micrometers of a higher electrically conductive support which allows increasing fuel cell efficiency with a very low catalyst loading. Carbon nanofibers (CNF) were successfully grown on an electrode backing covered by a thin nickel layer using a Chemical Vapor Deposition in a high density helicon plasma processing reactor that I designed, built and commissioned. I have characterised the morphology of CNFs produced using different plasma deposition parameters and optimized the process for the fuel cell applications. This has included using a Helicon sputtering plasma to cover by platinum nanoparticles.
