(ZA9502384-A)      Modified polymeric cation exchange membrane for an electrochemical cell comprises an ionic Ag, W and/or Mo salt deposited within a polymer matrix, the salt being insoluble in the electrolytes contacting either side of the membrane in use. Also claimed are (i) an electrochemical appts. comprising cell(s) contg. the membrane(s); and (ii) a method of preparing the membrane by contacting a cation exchange membrane with an aq. soln. of the salt(s) and then converting the salt(s) into insoluble salt(s).    USE -   Used in chlor-alkali cells, fuel cells, and energy storage/power delivery devices.    ADVANTAGE -   The membranes combine low resistivity with high permselectivity.
