ABSTRACT:
A modified polymeric cation exchange membrane for use in an electrochemical cell, the membrane having a salt selected from the group consisting of silver, tungsten, molybdenum and a mixture thereof deposited within the polymer matrix, the salt being insoluble in the electrolytes which, in use, contact either side of the membrane.
The membranes are of particular use in electrochemical cells and combine a low electrolytic resistivity with a high permselectivity.
