摘要

PPROBLEM TO BE SOLVED: To provide a polymer electrolyte material and a polymer electrolyte membrane which have excellent proton-conductivity, fuel separation, mechanical strength, physical durability, hot water resistance, hot methanol resistance, processability and chemical stability and, when used in a polymer electrolyte, achieves a high output, a high energy density and a long durability and a polymer electrolyte part, polymer electrolyte membrane, membrane electrode composite and polymer electrolyte-type fuel cell using these. PSOLUTION: The polymer electrolyte material comprises an ionic group-containing polymer having a crystallization peak observed by differential scanning calorimetry. The polymer electrolyte part, polymer electrolyte membrane, membrane electrode assembly and polymer electrolyte-type fuel cell are composed by using the polymer electrolyte material.
