Recycling of Fuel Cell/Electrolyzer Membrane Electrode Assemblies

Since platinum group metals are considered as the most efficient catalysts in proton exchange membrane fuel cells/Electrolyzers, the demands have constantly increased these years. Due to their limited reserves and irreplaceable role in the industry, recycling of the membrane electrode assemblies(MEA) are critical to achieve sustainable clean energy supplies. Different from conventional pyrogenic process, we developed a green method to selectively extract each precious metals from fuel cell/Electrolyzers MEAs with high efficiency and recycle florine-contained ionomers to reduce their detrimental influence to the environment.
