8343324, Jan 1, 2013

Filed:

Mar 3, 2010

Appl. No.:

12/716457

Inventors:

Carl A. Koval - Arvada CO, US
Christine E. Evans - Fayetteville AR, US
Richard D. Noble - Boulder CO, US
Mya A. Norman - Springdale AR, US

Assignee:

The Regents of the University of Colorado - Denver CO

International Classification:

B01D 61/42
B01D 69/00

US Classification:

204518, 204627

Abstract:

The invention provides electrochemically-based methods and devices for producing fluid flow and/or changes in fluid pressure. In the methods and devices of the invention, current is passed through a divided electrochemical cell. Adjacent compartments of the cell are divided by a separator which comprises an ionically conducting separator. Each compartment includes an electrode and an electrolyte solution or ionic liquid. The electrolyte solution(s) or ionic liquid(s) and the ionically conducting separator are selected to obtain the desired relationship between the current through the cell and the fluid flowrate and/or change in fluid pressure.
