Perfluorinated Ion-Exchange Membranes: Development and Application

By Shintaro Hayabe, Kousuke Sumikura and Masahiro Ohkura |

Perfluorinated ion-exchange membranes are developing beyond legacy applications to find use in a wide variety of emerging markets, including renewable energy Ion-exchange membranes are used in numerous industrial processes, including seawater desalination, electrodialysis and the production of commodity chemicals via chlor-alkali processes. A membrane’s materials of construction play an extremely important role in its performance in a given application. For example, ion-exchange membranes based on perfluorinated sulfonic acid (PFSA) polymer show high performance under severe operating conditions. These membranes are available in various grades differing in ion-exchange capacity (IEC) and membrane thickness in order to help end users choose a suitable membrane for their application. Such membranes were originally developed for use in the chlor-alkali industry, but are now used in many kinds of industrial electrolysis applications, such as hydrochloric acid electrolysis and organic-salt electrolysis, and in various electrochemical devices, such as fuel cells and water electrolyzers. In addition, next-generation membranes designed for polymer electrolyte membrane (PEM) water electrolysis are being developed to achieve low membrane…
