Method for producing a polymer electrolyte molded

PROBLEM TO BE SOLVED: To provide a manufacturing method of a polyelectrolyte mold which has an excellent proton conductivity, a fuel blocking property, mechanical strength, a heat resistant methanol property, processability, chemical stability, as well as a high output, a high energy density and a long durability when installed in a polyelectrolyte fuel cell, and provide a polyelectrolyte material, a membrane electrode complex and a polyelectrolyte fuel cell using the above composite. SOLUTION: The manufacturing method of a polyelectrolyte mold includes a process of molding a polyelectrolyte material including at least a protective group and an ionic group, and then deprotecting at least a part of the protective group contained in the mold. The polyelectrolyte material, the membrane electrode complex and the polyelectrolyte fuel cell are manufactured by the manufacturing method of the above polyelectrolyte membrane.
