Abstract:
Disclosed herein is an electrolyte membrane for a fuel cell. The electrolyte membrane includes a blend of polymers with different degrees of sulfonation. The electrolyte membrane can exhibit excellent effects such as improved long-term cell performance and good long-term dimensional stability while at the same time solving the problems of conventional hydrocarbon electrolyte membranes. Further disclosed are a membrane-electrode assembly and a fuel cell including the electrolyte membrane.
