Researchers from Drexel University Detail Findings in Nanofibers (Nanofiber Cathode Catalyst Layer Model for a Proton Exchange Membrane Fuel Cell)

August 8, 2014

By a News Reporter-Staff News Editor at Energy Weekly News -- Fresh data on Nanofibers are presented in a new report. According to news reporting from Philadelphia, Pennsylvania, by VerticalNews journalists, research stated, "The cathode catalyst layer in a proton exchange membrane fuel cell is now known to contain ionomer nanofibers and experiments have demonstrated a fuel cell performance increase of similar to 10% due to those nanofibers. The experiments demonstrate that ionomer nanofibers have proton conductivities that exceed those of the bulk form of the ionomer by more than an order of magnitude."

The news correspondents obtained a quote from the research from Drexel University, "A new model of a proton exchange membrane fuel cell is presented here that predicts the effect of nanofibers on cell performance in terms of the enhanced nanofiber proton conductivity and other relevant variables. The model peak cell power density is similar to 7% greater for the case with 10% of the cathode catalyst layer ionomer in nanofiber form versus the same case without nanofibers. This difference is consistent with trends observed in previously published experimental results."

According to the news reporters, the research concluded: "These results are significant since they suggest alternative methods to reduce platinum loading in fuel cells and to optimize fuel cell performance."
