Article: Findings from Australian National University provide new insights into applied physics.

"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," scientists in Canberra, Australia report.

"Initially, the Nafion (R) loading spread on these plasma prepared electrodes is optimized by measuring the MEA performance. It is found that the optimum Nafion (R) loading is 1mg cm(-2) for an ...
