Abstract

The invention relates to a method for recycling membrane/electrode units (MEA) of a fuel cell, comprising proton-exchange membrane material (PEM) and gas-diffusion layers (GDL), said PEM containing a perfluorsulfonic acid polymer (PFSA) and precious metal, under the effect of ultrasound and in the presence of a solvent for separating the precious metal from the fluorine-containing membrane material by means of a filtration process, having the following steps: - comminuting the precious metal-loaded MEA into chips, flocs, or flakes; - transporting the comminuted precious metal-loaded MEA into an ultrasonic bath filled with a solvent (LM) made of aqueous ethanol; - subjecting the MEA membrane material to an ultrasonic treatment in the solvent (LM), said precious metal passing into the solvent (LM); - separating the fluorine-containing membrane material (PFSA) from the precious metal-loaded solvent (LM); - feeding the fluorine-containing membrane material (PFSA) to a thermal or material recovery process; - filtering the precious metal-loaded solvent (LM) and obtaining a precious metal-loaded filter material; and - recovering the precious metal from the loaded filter material using a conventional thermal method.
