Abstract
A low energy method and system of removing H+ from a solution in an electrochemical cell wherein on applying a voltage across an anode in a first electrolyte and a cathode in second electrolyte, H+ are transferred to second electrolyte through a proton transfer member without forming a gas, e.g., oxygen or chlorine at the electrodes.
Claims78
An electrochemical method comprising:
- biasing a voltage on a first electrode positive relative to a conductive proton transfer member, and
- biasing a voltage on a second electrode negative relative to the proton transfer member to establish a current through the first and second electrodes in an electrochemical system wherein
- the proton transfer member isolates the first electrolyte from a second electrolyte, the first electrolyte contacts the first electrode and the second electrolyte contacts the second electrode.

A method of removing protons from an electrolyte, comprising:
- isolating a first electrolyte from a second electrolyte utilizing a proton transfer member;
- and
- biasing a voltage on a first electrode contacting the first electrolyte positive relative to the proton transfer member, and a voltage on the second electrode contacting the second electrolyte negative relative to the proton transfer member wherein
- said voltages cause protons to be removed from said first electrolyte and introduced into said second electrolyte.
