  "textContent": "A polymer electrolyte membrane including a porous polymer matrix; and an ion conducting polymer coating membrane formed in the outer face of a single fiber in the porous polymer matrix is provided. 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, and thus is suitable for a fuel cell for using at high temperature. When the polymer matrix constituting the polymer electrolyte membrane made of a hydrophobic material is used in the direct methanol fuel cell, the crossover of the methanol can be effectively blocked.",
