Abstract
A converter includes a working fluid, a housing, a heat sink, a heat source that is at an elevated temperature relative to the heat sink, a first electrochemical cell disposed within the housing, and a micro/nano porous media disposed within the housing. The first electrochemical cell includes a first membrane electrode assembly across which the working fluid is configured to flow. The first membrane electrode assembly includes a first porous electrode and a second porous electrode and at least one ion conductive membrane sandwiched between the first and second porous electrodes. The first electrochemical cell is arranged between the heat source and the heat sink. The working fluid is contained within the micro/nano porous media. The micro/nano porous media is thermally coupled between the heat source and the heat sink, and creates a pressure differential across the first electrochemical cell by transpiration pumping of the working fluid.
