ABSTRACT:
Electrode structures for fuel cells are made by blending noble metal black, dry polytetrafluoroethylene and a soluble bulking agent in a liquid, filtering liquid from the blend and rolling the remnant to form a sheet of fibrillated polytetrafluoroethylene containing noble metal black and bulking agent. The bulking agent may be leached from the sheet and the sheet then pressed or the sheet may be first pressed and the bulking agent then leached from the sheet.
