Effect of Nafion and platinum content in a catalyst layer processed in a radio frequency helicon plasma system

Caillard, Amael; Charles, Christine; Ramdutt, Devien; Boswell, Roderick; Brault, Pascal


A helicon plasma sputtering system is used to deposit small amounts of platinum on microporous carbon support composed of Vulcan XC 72 carbon particles (known as gas diffusion layer) to form Pt catalyzed electrodes for proton exchange membrane fuel cells. Electrodes with low Pt loading are prepared, assembled in custom-made membrane electrode assemblies (MEAs) and tested for the hydrogen oxydation and the oxygen reduction. Initially, the Nafion loading spread on these plasma prepared electrodes...[Show more]
