Abstract
The present invention relates to a polymer electrolyte membrane that includes a porous polymer matrix and an ion conducting polymer coating membrane formed in the outer surface of single fibers in the porous polymer matrix. The polymer electrolyte membrane can provide excellent mechanical strength, is not deteriorated by heat even at a temperature higher than 100°C., can provide excellent ion conductivity even at non-humidified state. Thus it is suitable for use in a fuel cell that is operated at high temperatures.
