| description | PROBLEM TO BE SOLVED: To provide a polymer electrolyte material which is excellent in durability and the power generation performance of a membrane at a high-temperature low-humidification environment, and a polymer electrolyte fuel cell using the polymer electrolyte material. SOLUTION: In the polymer electrolyte material which is a block copolymer having a hydrophobic polymer block not containing a sulfonic acid group and a hydrophilic polymer block containing a sulfonic acid group, the hydrophobic polymer block is expressed by general formula (1) (in the formula, m denotes an integer of 2 or larger), and the hydrophilic polymer block is expressed by general formula (2) (in the formula, n denotes an integer of 2 or larger).
