Turning exhaust gases into electricity, an innovative prototype

high temperature fuel cell

Jean-Paul Viricelle, a researcher in process engineering at Mines Saint-Étienne, has created a small high-temperature fuel cell composed of a single chamber. Placed at the exhaust outlet of the combustion process, this prototype could be used to convert unburned gas into energy.   Following the government’s recent announcements about the …
