A polymer electrolyte membrane is provided with a cation exchange resin and a mineral additive including an exfoliated layered silicic acid-based clay. The polymer electrolyte membrane includes the nano-sized exfoliated mineral additive dispersed in the polymer electrolyte membrane, and thereby fuel cross-over can be effectively suppressed by the small amount of mineral additive while maintaining excellent ion conductivity and mechanical properties.
