MACROMOLECULAR ELECTROLYTE MEMBRANE FOR A FUEL CELL, AND A MEMBRANE ELECTRODE BINDER MATERIAL AND A FUEL CELL COMPRISING THE SAME

摘要

The present invention relates to a macromolecular electrolyte membrane for a fuel cell, and to a membrane electrode binder material and a fuel cell comprising the same, and provides a macromolecular electrolyte membrane for a fuel cell comprising a cation exchange resin based on a hydrogen-ion-conducting hydrocarbon and comprising fibrous nanoparticles having a hydrophilic group. By using fibrous nanoparticles having a hydrophilic group in a mixture with a cation exchange resin based on a hydrogen-ion-conducting hydrocarbon, the present invention can provide a macromolecular electrolyte membrane having improved gas-screening properties and long-term durability without reducing the performance of the fuel cell, and can provide a fuel cell which comprises the macromolecular electrolyte membrane.
