A new, milder sulfonation process was used to produce ion-exchange polymers from a commercial polysulfone (PSU). Membranes obtained from the sulfonated polysulfone are potential substitutes for perfluorosulfonic acid membranes used now in polymer electrolyte fuel cells. Sulfonation levels from 20 to

## Abstract In alkaline fuel cells (AFC) silver can be used as the cathode catalyst in gas diffusion electrodes. To prepare the gas diffusion electrodes, the metal catalyst was mixed with polytetraflourethylene (PTFE), as the organic binder, in a knife mill and rolled onto a metal web in a calender
## Abstract An inorganic filler prepared by impregnation of phosphotungstic heteropolyacid on zirconia (HPW/Zr) was developed to be inserted into a perfluorosulphonic polymer matrix for a polymer electrolyte fuel cell (PEFC) operating at a medium temperature (80β120βΒ°C) and low relative humidity (R
