PURPOSE: A polymer electrolyte membrane and a fuel cell are provided to enhance an electrochemical stability, a thermal stability and a conductivity of a hydrogen ion under high temperatures, thereby being applicable in the solid polymer electrolyte fuel cell. CONSTITUTION: A polymer electrolyte membrane and a fuel cell comprises a styrene repeating unit including a sulfonated styrene, a block copolymers including an alkylene recurring unit, and an ionic liquid of an imidazolium salt which contains a negative ion containing a sulfur element. The block copolymers are copolymers marked as chemical formula 1. In the chemical formula 1, R1-R4 are independently grouped as hydrogen, C1-C20 alkyl group, C2-C20 alkenyl group, or C6-C20 aryl group, and a is indicating 5-500, b is indicating 5-700, n is indicating 0.01-1, and X is indicating 0-0.99. |
