Abstract
A heat to electricity converter including a working fluid and a pair of membrane electrode assemblies (MEA) is provided. Each MEA includes a pair of electrodes which are electron conductive and permeable to the working fluid, and a thin film electrolyte membrane sandwiched between the electrodes. The membrane is conductive of ions of the working fluid and has a thickness of 0.03 μm to 10 μm. At least one electrode of each MEA includes a non-porous and dense metal. One electrode of each MEA is in contact with the working fluid at a first, higher pressure, while the other electrode is in contact with the working fluid at a second, lower pressure. The first MEA is configured to compress the working fluid from the second pressure to the first pressure, while the second MEA is configured to expand the working fluid from the first pressure to the second pressure.
