    • PROBLEM TO BE SOLVED: To efficiently recover a precious metal and a fluorine-containing polymer without using a solvent or the like from a membrane-electrode bonded element (MEA) of a used solid polymer electrolyte fuel cell. SOLUTION: The membrane-electrode bonded element (MEA) is constituted of an electrolyte membrane comprising the fluorine-containing polymer having a sulfonic acid group, a conductive carrier which is bonded to the electrolyte membrane and carries a catalyst metal, and a gas diffusing electrode (b) of which the major constituent material is a catalyst layer comprising a proton conductive polymer. The precious metal and/or the fluorine-containing polymer having the sulfonic acid group are recovered from the membrane-electrode assembly (MEA) by this recycling method. The recycling method has two processes, (1) a process in which the membrane-electrode assembly (MEA) is solidified, and the electrolyte is expanded to a degree wherein the plastic deformation of the catalyst layer after the solidification becomes easier, (2) a process in which the membrane-electrode assembly (MEA) after the electrolyte has been expanded is solidified while imparting a stress. By these processes, the electrolyte membrane comprising the fluorine-containing polymer having the sulfonic acid group, and the catalyst layer comprising the conductive carrier carrying the catalyst metal and the proton conductive polymer are made easily separable.
