Abstract

The physical properties and preliminary hydrogen fuel cell performance data of sulfonated Diels-Alder (DA) polyphenylenes were presented. Sulfonated DA polymers were readily cast into films from NMP. These films were robust and showed no forms of brittleness even when dried. The films displayed proton conductivities ranging from 10-80 mS/cm while still maintaining mechanical stability (swelling under 50%). Fuel cell performance data indicated that the sulfonated DA polymers could obtain high power levels and current densities of 342 mw/sq cm at 800 mA/sq cm.
