The present invention relates to a polymer electrolyte membrane for a fuel cell, a membrane electrode assembly including the same, and a fuel cell, and provides a polymer electrolyte membrane for a fuel cell including a cation exchange resin having a hydrogen ion conductivity and a natural fiber filler. According to the present invention, by using a natural fiber filler mixed with a hydrogen ion conductive cation exchange resin, it is possible to provide a polymer electrolyte membrane having improved gas barrier properties and long-term durability without degrading the performance of the fuel cell. It is possible to provide a fuel cell comprising the same. |
