  • Hollow platinum nanoparticles for fuel cells
    Patent number: 9755246
    Abstract: The present invention relates to hollow platinum nanoparticles with a diameter comprised between 3 and 20 nm which comprise a first central cavity and optionally at least one second cavity at the periphery of the first cavity, the shell of which is dense and single-crystal with a thickness comprised between 0.2 and 5 nm. The invention also relates to a method for manufacturing such nanoparticles, as well as to their use as an electrocatalyst in fuel cells.

  • Fuel cell with flat assembly and simplified sealing
    Patent number: 8142940
    Abstract: A flat fuel cell including: at least two unit cells, a casing provided with supports for each of said unit cells, said supports offering a bearing surface to a periphery of the unit cells, a sealing member interposed between the periphery of each unit cell and the surface of an associated support, and a cover forming a compression element coming into abutment on the periphery of each unit cell opposite the sealing member and cooperating directly with the associated support in order to provide compression of the sealing member.
