Abstract: A composite polymer electrolyte membrane for a fuel cell may be manufactured by the following method: partially or totally filling the inside of a pore of a porous support with a hydrogen ion conductive polymer electrolyte solution by performing a solution impregnation process; and drying the hydrogen ion conductive polymer electrolyte solution while completely filling the inside of the pore with the hydrogen ion conductive polymer electrolyte solution by performing a spin dry process on the porous support of which the inside of the pore is partially or totally filled with the hydrogen ion conductive polymer electrolyte solution.

Abstract: Disclosed is a carbon support for a fuel cell catalyst that supports a metal. The carbon support includes a conductive carbon support and nitrogen atoms doped into the conductive carbon support. Also disclosed is a method for preparing the carbon support. Also disclosed is a catalyst including the carbon support. The catalyst has greatly improved degradation resistance compared to conventional catalysts for fuel cells. In addition, the catalyst is not substantially degraded even when applied to a single cell.
