A method of recycling a waste ionomer material

Resumen de: GB2700586A

Waste ionomer material, which is preferably a persulfonic acid ionomer, and preferably is obtained from waste proton exchange membranes from fuel cells or electolysers, is heated in a solvemt to form a dispersion. The dispersion is subsequently subjected to a membrane filtration process to remove contaminants. Preferably, the membrane filtration is a crossflow filtration process, most preferably a hollow fibre membrane. In some embodments, the pore size of the membrane is 35-400 nm. The ionomer may be treated with a chelating agent and may be converted into salt form. Concentration and diafiltration steps may also be included. Figure 1
