Precious-metal catalysts (predominantly Pt or Pt-based alloys supported on carbon) have traditionally been used to catalyze the electrode reactions in polymer electrolyte membrane (PEM) fuel cells. However as PEM fuel systems begin to approach commercial reality, there is an impending need to replac
## Trends Sulfonated poly(arylene ether sulfone) copolymers for PEMs Here novel biphenol-based wholly aromatic poly(arylene ether sulfone)s containing up to two pendant sulfonate groups per repeat unit were prepared by direct aromatic nucleophilic substitution polycondensation of disodium 3,3'disul
