  • Polymer composition by continuous filler slurry extrusion
    Patent number: 10435521
    Abstract: An inventive process for the production of a polymer composition is provided, said process comprising the incorporation of a filler into a polymer material, wherein said polymer material during incorporation of the filler is in at least partially molten state and wherein said filler is incorporated as a slurry.

  • Membrane electrode assembly for use in electrochemical devices
    Patent number: 8394551
    Abstract: The invention relates to a membrane-electrode assembly (MEA) for electrochemical devices, in particular for membrane fuel cells. The membrane-electrode assembly has a semi-coextensive design and comprises an ion-conducting membrane, two catalyst layers and gas diffusion layers of differing sizes on the front side and rear side. The first gas diffusion layer has smaller planar dimensions than the ion-conducting membrane, while the second gas diffusion layer has essentially the same planar dimensions as the ion-conducting membrane. As a result, the ion-conducting membrane has a surface which is not supported by a gas diffusion layer on the front side. The membrane-electrode assembly has, owing to the particular construction, a stable structure which can be handled readily and displays advantages in the sealing of the reactive gases from one another and also in terms of the electrical properties. In particular, the hydrogen penetration current is significantly reduced.
