Water recapture/recycle system in electrochemical cells

A method for managing water content in one or more electrochemical cells, each comprising a plurality of electrodes and a liquid ionically conductive medium, the method comprising:

• receiving humid air from the one or more electrochemical cells in a desiccator unit;
• extracting water from the humid air via the desiccator unit;
• selectively heating the desiccator unit to selectively release extracted water from the desiccator unit;
• and
• directing the extracted water from the desiccator unit to the ionically conductive medium.

An electrochemical cell system comprising:

• an electrochemical cell comprising:
• a fuel electrode,
• a liquid ionically conductive medium,
• an air chamber, and
• an oxidant reduction electrode having one surface facing the ionically conductive medium and an opposite surface facing the air chamber;
• a first air conduit for receiving humid air from the air chamber of the electrochemical cell;
• a desiccator unit communicated to the first air conduit and configured for extracting water from the humid air;
• a heater for selectively heating the desiccator unit to selectively release extracted water from the desiccator unit;
• and
• a return conduit communicating the desiccator unit to the ionically conductive medium for receiving extracted water from the desiccator unit, and directing the extracted water to the ionically conductive medium.

A system for managing water content in a plurality of electrochemical cells, each comprising a plurality of electrodes and a liquid ionically conductive medium, the system comprising:

• a desiccator unit for storing water;
• a heater for selectively heating the desiccator unit to selectively release water vapor from the desiccator unit;
• and
• a plurality of return conduits, each associated with a respective cell for communicating the desiccator unit to the ionically conductive medium of each cell for receiving the water vapor from the desiccator unit;
• wherein each return conduit is configured to be blocked by a rising level of the liquid ionically conductive medium, thus providing back pressure to the flow of the water vapor so that the water vapor preferentially flows to the unblocked return conduit or conduits.
