Novel membrane and membrane electrode assemblies

摘要

An ion exchange membrane for use in an electrochemical cell is described. The ion exchange membrane includes: (i) a first layer capable of conducting ions when placed between two electrodes of the electrochemical cell; and (ii) a second layer disposed around at least a portion of the first layer, wherein the second layer is made from a perimeter strengthening material, such that the second layer strengthens at least a portion of a perimeter boundary of the first layer. Methods for making such ion exchange membranes and methods of making membrane electrode assemblies incorporating such membranes are also described.
