## 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
## Abstract Graphitised carbon nanofibres (GβCNFs) show superior thermal stability and corrosion resistance in PEM fuel cell environment over traditional carbon black (CB) and carbon nanotube catalyst supports. However, GβCNFs have an inert surface with only very limited amount of surface defects f
## Abstract Longβterm deterioration in the performance of PEFCs is attributed largely to reduction in active area of the platinum catalyst at cathode, usually caused by carbonβsupport corrosion. It is found that the use of graphitic carbon as cathodeβcatalyst support enhances its longβterm stabilit
