Patent number: 11482714Abstract: A fuel cell includes a flow guide, a component for allowing a first fluid to flow from a first manifold to a second manifold and through a reactive zone, a peripheral seal disposed between the flow guide and the component, an intermediate seal disposed between the flow guide and the component, the intermediate seal being encircled by the peripheral seal and encircling the reactive zone, another component opposite the flow guide to allow a second fluid to flow from a third manifold to a fourth manifold and through another reactive zone, and a fluid flow circuit provided between the intermediate seal and the peripheral seal between fifth and sixth manifolds. One of the fifth and sixth manifolds is separated from the first to fourth manifolds by the intermediate seal.Type: GrantFiled: December 12, 2018Date of Patent: October 25, 2022Assignee: Commissariat a l'energie atomique et aux energies alternativesInventors: Jean-Philippe Poirot-Crouvezier, Sebastien Rosini
