An electrolyte medium suitable for use as a separator for an electrochemical cell comprises a substantially solid, thermoset polyimide polymer matrix doped with a lithium salt. The lithium salt comprises lithium bis(trifluoromethanesulfonyl)imide (LITFSI).

Solid, lithium-salt-doped, thermoset polyimide polymer electrolyte and electrochemical cell employing same

There is disclosed an electrochemical conversion system () for energy management which includes multi-electrochemical cells. The systemincludes a conduit system (), an electrical system (), first electrochemical cell (), a second electrochemical cell (), a third electrochemical cell (), a first recuperative heat exchanger (RHX) (), and a second recuperative heat exchanger (). The conduit system, electrical system (), heat exchangers, and electrochemical cells are all constructed and function in the same manner as previously described. The system () also includes an additional, second recuperative heat exchanger () (RHX) to thermally isolate the third electrochemical cell from the other two. As shown, the electrochemical cells are electrically and pneumatically connected in series so that the electrical current flow and the proton flow through the electrochemical cells are balanced.

Electrochemical conversion system for energy management

An reversible engine () is disclosed having a conduit system (), a first electrochemical cells (), and a second electrochemical cell (). The conduit system () includes a first conduit () extending from the first electrochemical cell () to the second electrochemical cell (), and a second conduit () extending from the second electrochemical cell () to the first electrochemical cell (). The heat engine () also includes a heater () mounted in thermal communication with the conduit system () adjacent the second electrochemical cell (), a cooler () mounted in thermal communication with the conduit system () adjacent the first electrochemical cell (), and a regenerative heat exchanger () thermally coupled to the first and second conduits () and () for the transfer of heat therebetween.
