  • Process for producing a nanoporous layer of nanoparticles and layer thus obtained
    Patent number: 8137442
    Abstract: Process for producing at least one nanoporous layer of nanoparticles chosen from nanoparticles of a metal oxide, nanoparticles of metal oxides, and mixtures of said nanoparticles, on a surface of a substrate, in which at least one colloidal sol, in which said nanoparticles are dispersed and stabilized, is injected into a thermal plasma jet which sprays said nanoparticles onto said surface. Nanoporous layer and device, especially a separation device, comprizing said layer.
    Type: Grant
    Filed: April 25, 2007
    Date of Patent: March 20, 2012
    Assignee: Commissariat a l'Energie Atomique
    Inventors: Bruno Pintault, David Guenadou, Luc Bianchi, Philippe Belleville, Karine Valle, Christophe Boscher, Joël Toulc'Hoat
  • Sealed fuel cell stack
    Patent number: 8062806
    Abstract: The invention relates to a fuel cell consisting of a stack of elementary cells and interconnectors (7) and comprising a single vertical seal (2) which is placed around the stack thus formed. The aforementioned assembly is preferably equipped with a containment tube (1) which is placed around the vertical seal (2). Supply channels (11 and 12) in the interconnectors and lateral inlet and outlet (13 and 14) holes can be used to supply distribution channels (9 and 10) which are positioned against the electrodes of each elementary cell. The invention is suitable for SOFC-type fuel cells.

  • DEVICE TO INJECT A LIQUID FEED TO BE MIXED/CONVERTED INTO A PLASMA PLUME OR GAS FLOW
    Publication number: 20100237048
    Abstract: A device to inject liquid matter into a plasma torch, comprising N(N?1) groups of injectors arranged on the periphery of a flow region of the plasma, each group comprising at least n (n?2) injectors which are arranged either side of the plasma flow axis, so as to inject said liquid matter into the plasma in a direction at least partly opposite the direction of plasma flow.
