Abstract
Provided are a polymer electrolyte membrane for fuel cells, and a membrane electrode assembly and a fuel cell including the same. More specifically, provided is a polymer electrolyte membrane for fuel cells including a hydrocarbon-based cation exchange resin having hydrogen ion conductivity and fibrous nanoparticles having a hydrophilic group. By using the fibrous nanoparticles having a hydrophilic group in conjunction with the hydrocarbon-based cation exchange resin having hydrogen ion conductivity, it is possible to obtain a polymer electrolyte membrane for fuel cells that exhibits improved gas barrier properties and long-term resistance, without causing deterioration in performance of fuel cells, and a fuel cell including the polymer electrolyte membrane.
