Patent number: 8105727Abstract: The invention concerns a bipolar plate for fuel cell, of the type comprising a cathode bipolar half-plate and an anode bipolar half-plate attached to each other, each bipolar half-plate (1) consisting of a plate including in its central part an active region (2) and at its peripheral part a plurality of cut-outs (4) designed to form at least two oxidant boxes, at least two fuel boxes and at least two coolant boxes, the bipolar plate including at least one connecting channel between each peripheral cut-out and the active region. The invention is characterized in that each connecting channel of a peripheral cut-out with the active region consists of at least one rib (8) in a bipolar half-plate.Type: GrantFiled: June 23, 2006Date of Patent: January 31, 2012Assignees: Peugeot Citroen Automobiles SA, Commissariat a l'Energie Atomique et aux Energies AlternativesInventors: Damien Lemasson, Guillaume Joncquet, Jean-Philippe Poirot-Crouvezier

Patent number: 7964321Abstract: The invention relates to a bipolar plate for a fuel cell, of the type that comprises anode and cathode bipolar half plates (1, 1?) which are placed next to one another. The central part of each bipolar half plate comprises an active zone (2), while the periphery thereof comprises a plurality of cut-outs (4, 4?, 5, 5?, 6) which are intended to form at least two oxidant tanks, two fuel tanks and two coolant tanks. Moreover, at least one bipolar half plate comprises at least one connecting rib (8, 8?, 10, 12) between a peripheral cut-out and the active zone. Projecting out from the outer face, each coolant tank cut-out is surrounded by a sealing rib (7, 7?) and the periphery of each bipolar half plate comprises a rib (15, 15?) for sealing the active zone, which connects the coolant tank sealing ribs and which surrounds the oxidant and fuel tanks. Furthermore, each channel formed by a rib segment (15, 15?) between two coolant tanks is blocked by a blocking means (17, 17?).Type: GrantFiled: June 22, 2006Date of Patent: June 21, 2011Assignee: Commissariat A l'Energie AtomiqueInventors: Francis Roy, Damien Lemasson, Jean-Philippe Poirot-Crouvezier, Patrick Le Gallo

Patent number: 7713647Abstract: The invention mainly concerns a fuel cell seal (52) designed to be affixed on a bipolar plate (22) in the form of a membrane whereof the profile corresponds approximately to the peripheral frame (50) of the bipolar plate (22) and comprising a central opening (66) coinciding approximately with the central zone (46) dispensing the reagents of the bipolar plate (22). The invention also concerns a fuel cell comprising an electrode membrane assembly (70) which includes in particular an active region (74), which is the site of anode and cathode reactions, and a peripheral frame (75) and which is sandwiched between two bipolar plates (22) whereon is affixed the inventive seal (52).Type: GrantFiled: June 23, 2006Date of Patent: May 11, 2010Assignees: Peugeot Citroen Automobiles SA, Commissariat a l'Energie AtomiqueInventors: Damien Lemasson, Xavier Glipa, Francis Roy, Jean-Philippe Poirot-Crouvezier, Patrick Le Gallo
