Abstract
An electrochemical cell employs an ionic semiconductor material as a separator between an anolyte and a catholyte. Ionic semiconductor material includes 10 to approximately 50 percent by weight of a hydrogel which is dispersed within an inert nonporous matrix material to form a composite wherein the quantity of water that can be absorbed by the composite does not substantially exceed the weight of the composite.
Claims5
An electrochemical cell comprising:
- an anode;
- an anolyte;
- a cathode;
- a catholyte, the catholyte having a different pH when compared to the anolyte;
- a membrane separating said anolyte from said catholyte, said membrane comprising a nonporous solid composite material which is formed by a hydrogel substantially uniformly dispersed throughout an inert man made matrix material with said hydrogel comprising approximately 10 to 50% by weight of the dry composite material, ions selectively passing through said membrane from said anolyte to said catholyte whereby an electric current may flow through an external circuit connected between said anode and said cathode.
