1. An electrochemical energy store, comprising:
- a plurality of cells, each including;
an anode;
a cathode;
a solid electrolyte between the anode and the cathode, wherein the anode is disposed adjacent to a first side of the solid electrolyte and the cathode is disposed adjacent to a second side of the solid electrolyte that is opposite the first side so that the solid electrolyte separates completely the anode from the cathode;
a gas chamber at least partially delineated, and separated from the anode and electrolyte, by the cathode; and
a valve connected to the gas chamber;
an oxygen reservoir connected to the valve of each of the plurality of cells; and
a control system having a plurality of control lines, each connected to the valve of a respective different one of the plurality of cells to individually control an oxygen supply to the gas chamber of the respective cell.
