There are several conventional methods for recycling the membrane electrode assemblies (MEA) found in fuel cells. There are chemical techniques that deal with MEAs in bulk, including a method that dissolves the electrolyte film and a method that recovers the catalyst as a residue after incinerating it harmlessly. There are also physical techniques where the electrodes are detached from the MEA one by one. The former approach has a tendency to ignore the recovery of electrolyte film. Moreover… CONTINUE READING
