Abstract
An energy recovery converter for exhaust gases or waste heat is provided. The converter includes a membrane electrode assembly (MEA), an exhaust gas having a first molecular oxygen content, and an external electrical load. The MEA includes a first electrode, a second electrode and an oxygen ion conductive membrane sandwiched between the first and second electrodes. Each of the first and second electrodes includes at least one oxidation catalyst configured to promote an electrochemical reaction. The second electrode of the MEA is exposed to the exhaust gas and the first electrode of the MEA is exposed to a gas having a second molecular oxygen content. The second molecular oxygen content is higher than the first molecular oxygen content. The external electrical load is connected between the first and second electrodes of the MEA.
