摘要

PROBLEM TO BE SOLVED: To provide a polymer electrolyte composition having high chemical stability, and reduction of the oxidative deterioration prevention effect of which is small even during long time operation of a fuel cell or a water electrolysis device.SOLUTION: A polymer electrolyte composition contains a polymer electrolyte (A), a straight polyarylene sulfide (B1) and/or an annular polyarylene sulfide (C1). (In general formula (B1), n represents an integer of 3 or more, and Arrepresents an arylene group). (In general formula (C1), n represents an integer of 3 or more, and Arrepresents an arylene group).SELECTED DRAWING: None
