Abstract
The present invention relates to a polymer electrolyte membrane, and a membrane-electrode assembly and a fuel cell containing the same, and the polymer electrolyte membrane comprises a polymer comprising repeating units represented by the following chemical formulas 1-3. Chemical formulas 1-3 are as defined in the specification. The polymer electrolyte membrane has excellent resistance to radical attack and has improved acid-base interaction, thereby maximizing the function of an ion conductive group, and thus can improve the operation performance of a fuel cell in a low humidification state.
