摘要： Disclosed is a polymer electrolyte membrane for a fuel cell, which restrains a crossover phenomenon of fuel and a decomposition of a polymer membrane over platinum, and shows outstanding power output and performance characteristics during operation of the fuel cell, and a method for producing the same. The method comprises the steps of blending a polymer matrix with a fluorinated ionomer of 3 to 50 wt % based on a weight of a polymer to produce a blended polymer solution; casting the blended polymer solution into a polymer membrane; and coating the fluorinated ionomer on both sides of the polymer membrane to produce a composite membrane. The polymer electrolyte membrane has advantages in that the fuel cell using the polymer electrolyte membrane, which has high energy efficiency, can be inexpensively produced, and so the fuel cell can be applied in various applications such as a power source of a nonpolluting car, on-site generation of electricity, an electric power source of a spacecraft, a portable energy source, and an energy source for military purpose.
