Abstract
Official abstract text for this publication.
Disclosed herein are ion exchange membranes, electrochemical systems, and methods that relate to various configurations of the ion exchange membranes and other components of the electrochemical cell.
First claim
Opening claim text (preview).
What is claimed is: 1. An ion exchange membrane (IEM), comprising: an ionomer membrane with a built-in separator wherein one or more sections of the built-in separator protrude out from front and back surfaces of the ionomer membrane, wherein the built-in separator is a mesh and wherein the built-in separator is made of polyether ether ketone. 2. The ion exchange membrane of claim 1 , wherein amplitude of the protrusion is from 0.01 mm to 1 mm. 3. The ion exchange membrane of claim 2 , wherein wavelength of the amplitude of the protrusion is from 0.5 mm to 50 mm. 4. The ion exchange membrane of claim 1 , wherein an average thickness of the ionomer membrane is from 10 μm to 250 μm. 5. The ion exchange membrane of claim 1 , wherein ratio of cross-sectional area of the built-in separator to nominal cross-sectional area of the IEM is between about 5-70%. 6. The ion exchange membrane of claim 1 , wherein the built-in separator is configured to separate the IEM from an anode; separate the IEM from a cathode; separate the IEM from another IEM; or combinations thereof. 7. The ion exchange membrane of claim 1 , further comprising a gasket material integrated with the IEM. 8. The ion exchange membrane of claim 7 , wherein the gasket material is integrated to the edges of the IEM. 9. The ion exchange membrane of claim 7 , wherein the gasket material is integrated on front, back, or both sides of the IEM. 10. The ion exchange membrane of claim 7 , wherein the gasket material is of thickness between about 0.01 mm to 5 mm. 11. The ion exchange membrane of claim 7 , wherein the gasket material is made of silicone, viton, rubber, cork, felt, foam, plastic, fiber glass, flexible graphite, mica, or polymer.
