ABSTRACT:
This invention is directed to electrodialysis, electrochemical membrane cells and particularly to components comprising the ion-exchange membranes. These membranes are fabricated containing a reinforcing structure comprised of non-woven carbon fibers derived for example from carbonized polyacrylonitrile. The membranes so produced have a low D.C. electrical resistance (increased conductivity) which enables electrodialysis to be performed more economically.
