Patent number: 9698432Abstract: A fuel cell includes three membrane-electrode assemblies. and first and second bipolar metal plates interposed between the membrane-electrode assemblies. Each of the bipolar plates comprises two metal sheets facing a respective membrane-electrode assembly and fixedly attached by welds. The two metal sheets comprise successive guiding channels for guiding gas extending in a common longitudinal direction. The guiding channels are distributed in a transversal direction The welds are made in bottoms of the guiding channel and include welds of the first bipolar plate and welds of the second bipolar plate. Some of the welds of the first bipolar plate are not superimposed on the welds of the second bipolar plate and are offset longitudinally and transversally relative to the welds of the second bipolar plate.Type: GrantFiled: May 25, 2012Date of Patent: July 4, 2017Assignee: Commissariat a l'énergie atomique et aux energies alternativesInventors: Remi Vincent, Jean-Philippe Poirot-Crouvezier, Pascal Schott

Publication number: 20130337357Abstract: The invention relates to a current collecting plate (50) for a fuel cell. According to the invention, the plate comprises a substantially constant thickness of an electrically conductive material along the stacking axis of the cells of the fuel cell, forming a plane at the end of the stack in order to collect the current from the fuel cell. The invention is characterised in that it comprises holes (52) pierced in the thickness of the material, extending parallel to the plane of the plate.Type: ApplicationFiled: February 1, 2012Publication date: December 19, 2013Applicants: Commissariat A L'Energie Atomique Et Aux Energies Alternatives, PEUGEOT CITROEN AUTOMOBILES S.A.Inventors: Xavier Glipa, Francis Roy, Eric Pinton, Pascal Schott, Sylvie Begot, Fabien Harel, Jean-Marc Le Canut
