Electrochemical heat transfer system

A heat transfer system, comprising:

• an electrochemical cell comprising a first electrode and a second electrode separated by a separator comprising an ion transfer medium, a first electrode fluid flow path in operative fluid communication with the first electrode between a first electrode fluid flow path inlet and a first electrode fluid flow path outlet, and a second electrode fluid flow path in operative fluid communication with the second electrode between a second fluid flow path inlet and a second fluid flow path outlet;
• a heat exchanger condenser including a heat rejection side in operative thermal communication with a heat sink;
• a heat exchanger evaporator including a heat absorption side in operative thermal communication with a heat source;
• a first heat transfer fluid flow loop from the first electrode fluid flow path outlet to a heat rejection side inlet of the heat exchanger condenser and from a heat rejection side outlet of the heat exchanger condenser to the second electrode fluid flow path inlet;
• a second heat transfer fluid flow loop from the second electrode fluid flow path outlet to a heat absorption side inlet of the heat exchanger evaporator, and from a heat absorption side outlet of the heat exchanger evaporator to the first electrode fluid flow path inlet;
• and
• a heat transfer fluid in the first and second heat transfer fluid flow loops, comprising an electrochemically active agent that reversibly transforms from a first compound to a second compound at the second electrode, and from the second compound to the first compound at the first electrode, wherein:
• the electrochemically active agent comprises a fluorinated organic compound including an electrochemically active substituent group, which reversibly transforms between said first and second compounds having different boiling points to provide a phase change of the first and second compounds in the heat exchanger condenser and in the heat exchanger evaporator, or
• the heat transfer fluid comprises the electrochemically active agent and an electrochemically non-active refrigerant in a mixture, wherein the electrochemically active agent reversibly transforms between the first and second compounds to provide different boiling points of the mixture and a phase change of the electrochemically non-active refrigerant in the heat exchanger condenser and in the heat exchanger evaporator.
