| titleOfInvention | Reuse method of fluorine-containing polymer |
| abstract | PROBLEM TO BE SOLVED: To select and recover a fluorine-containing polymer having a low degree of deterioration from a used polymer electrolyte fuel cell and reuse it. In a method of recovering and reusing a fluorinated polymer having a sulfonic acid group from a membrane-electrode assembly (MEA), (1) in a solvent that dissolves the fluorinated polymer having a sulfonic acid group. A step of dissolving the MEA to form a mixture of the fluoropolymer solution having a sulfonic acid group (electrolyte component) and an electrode component; and (2) an electrolyte component in the mixture obtained in the step, A step of solid-liquid separation into an insoluble part (noble metal component) containing a conductive support carrying a catalytic metal, (3) spectrum measurement of the electrolyte component obtained in the separation step, and the side chain of the fluoropolymer Determining the degree of deterioration using the spectrum resulting from the above as an index, and selecting a fluorine-containing polymer having a low degree of deterioration.
