Zusammenfassung:	The present invention relates to a method for producing a polymer electrolyte molded article, which comprises forming a polymer electrolyte precursor having a protective group and an ionic group, and deprotecting at least a portion of protective groups contained in the resulting molded article to obtain a polymer electrolyte molded article. According to the present invention, it is possible to obtain a polymer electrolyte material and a polymer electrolyte molded article, which are excellent in proton conductivity and are also excellent in fuel barrier properties, mechanical strength, physical durability, resistance to hot water, resistance to hot methanol, processability and chemical stability. A polymer electrolyte fuel cell using a polymer electrolyte membrane, polymer electrolyte parts or a membrane electrode assembly can achieve high output, high energy density and long-term durability.
