1. An electrochemical cell comprising:
- an anode;
a cathode;
a separator between the anode and the cathode, the separator allowing ionic conduction between the anode and the cathode but not allowing electrical conduction between the anode in the cathode, and a barrier configured, positioned, and dimensioned to be inserted between the anode and the cathode, wherein the barrier provides selective ionic isolation between the anode and cathode, or selective reduction of ionic conductivity between the anode and the cathode.

Abstract
Electrochemical cell systems are disclosed herein that are capable of selective ionic isolation, oxidant isolation, oxidant removal, moisture control, and combinations thereof. Selective ionic isolation is generally effectuated by selectively eliminating or minimizing ionic communication between an anode and a cathode of the electrochemical cell.
