Experimental Study for Separation of Membrane and Recovery of Platinum from MEA

Present paper reports a new method to separate the electrolyte membranes and carbon paper without using ultrasonic waves and stirring. In this method, these were separated from fuel cell membrane-electrode assembly(MEA) using the distilled water, butanol and surfactant by dipping method without the dispersion of catalyst particles. Separated carbon paper catalysts and fuel cell Pt/C catalysts were heated in aqua regia at and added to precipitant. After calcination, Pt metal was recovered which might be used in fabricating new fuel cells.
