Abstract:
A sulfonated copolymer including a crosslinking functional group and a fuel cell including a polymeric composition of the same are provided. The sulfonated copolymer including a crosslinking functional group can remarkably reduce methanol crossover and maintain superior dimensional stability and ionic conductivity by reducing swelling.
