AROMATIC POLYMER ELECTROLYTE HAVING SUPER-STRONG ACID GROUP, AND USE THEREOF

摘要

PPROBLEM TO BE SOLVED: To provide an aromatic polymer electrolyte having high mechanical strengths at a high temperature and good proton conductivity at a high temperature and low humidity, and to provide use thereof as a material for fuel cells. PSOLUTION: The aromatic polymer electrolyte includes a repeating unit including a structure having an aromatic ring in a main chain and a side chain and includes 1.3 or more super-strong acid groups per the repeating unit, wherein each super-strong acid group is introduced into a different aromatic ring in the structure.
