Patent number: 11239513Abstract: A direct heat to electricity engine includes solid state electrodes of an electrochemically active material that has an electrochemical reaction potential that is temperature dependent. The electrodes are configured in combination with electrolyte separators to form membrane electrode assemblies. The membrane electrode assemblies are grouped into pairs, whereby each membrane electrode assembly of a given pair is ionically and electronically interconnected with the other. One membrane electrode assembly of a given pair is coupled to a heat source with the other to a heat sink. One membrane electrode assembly of the pair is electrically discharged while the other is electrically charged, whereby the net and relative charge between the two remains constant because of the electronic and ionic interconnection and the difference in temperature of the membrane electrode assemblies, and thereby voltage, results in net power generation.Type: GrantFiled: August 10, 2017Date of Patent: February 1, 2022Assignee: JOHNSON IP HOLDING, LLCInventor: Lonnie G.
