NOVELTY - Separation of components of catalyst coated membranes involves dissolving the catalyst coated membranes into a slurry of water and solvent; subjecting the slurry to 190-290degreesC for an effective period of time to obtain a pulp material; filtering the pulp material; and separating the components from the filtrate to obtain a first portion containing at least a majority of the catalyst and a second portion containing the membrane material.    USE - The process is used for separating components of catalyst coated membranes, e.g. fabric reinforced perfluorosulfonic acid polymer membrane and catalyst coated fuel cell membranes. It is used for recycling used catalyst coated membrane material comprising fluorine containing polymer membrane and metal catalyst (all claimed).    ADVANTAGE - The process allows for the re-manufacture of new catalyst coated membranes from used catalyst coated membranes extracted from failed fuel cell stacks.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for:    (A) recovering used perfluorosulfonic acid membranes, comprising obtaining a slurry of water and solvent containing the catalyst coated membranes; subjecting the slurry to 500-2000 psi at 190-290degreesC in an autoclave to obtain a pulp material; filtering the pulp material to obtain a filtrate; and centrifuging the filtrate to separate the majority of the perfluorosulfonic acid membrane from the remainder of the filtrate; and recovering the perfluorosulfonic acid membrane material; and    (B) recycling used catalyst coated membrane material comprising fluorine containing polymer membrane and metal catalyst, comprising decontaminating the used catalyst coated membrane to remove impurities; dissolving the used catalyst coated membrane in water and a solvent a to form a slurry of dissolved fluorine containing polymer membrane together with the metal catalyst particles; subjecting the slurry to at least 190degreesC and pressure of at least 500 psi; separating the fluorine containing polymer membrane material from the metal catalyst; recovering the fluorine containing polymer membrane material and the metal catalyst and casting the recovered fluorine containing polymer membrane material into a recycled membrane.    DESCRIPTION OF DRAWING(S) - The figure is a diagram of methods of recycling used membrane electrolyte assemblies.
