  • THERMO-ELECTROCHEMICAL CONVERTER
    Publication number: 20230056025
    Abstract: A thermo-electrochemical converter is provided. The converter includes a working fluid, coupled first and second membrane electrode assemblies (MEA), first and second heat transfer members, a heat sink and a heat source. Each MEA includes a first porous electrode operating at a first pressure, a second porous electrode operating at a second pressure which is higher than the first pressure, and an ion conductive membrane sandwiched therebetween. The first MEA compresses the working fluid and the second MEA expands the working fluid. The first heat transfer member is coupled to and thermally interfaces with a low-pressure electrode of the first MEA. The second heat transfer member is coupled to and thermally interfaces with a lowpressure electrode of the second MEA. The heat sink is coupled to the low-pressure side of the first MEA and the heat source is coupled to the low-pressure side of the second MEA.
