  • Publication number: 20060205830
    Abstract: A porous filter medium forms a filter or liner for extracting hydrocarbons from vapors emitted from a motorized vehicle, device or appliance fuel tank. The filter medium is a polymer network of a foam, nonwoven or collection of particles and has fine pore size and a butane working capacity (W/W %) of 4.0 percent or higher.

  • Publication number: 20050130023
    Abstract: The invention relates to a gas diffusion layer, a device having the gas diffusion layer and a catalyst layer, a fuel cell containing the gas diffusion layer, and a gas diffusion electrode. The gas diffusion layer comprises a flexible, electrically non-conductive, porous material having a solid matrix, interconnected pores or interstices through the solid matrix, at least one external surface and internal surfaces, which internal surfaces are the surfaces of the walls of the pores or interstices, wherein at least a portion of the at least one external surface is coated with one or more layers of an electrically conductive material, the electrically conductive material comprising a mixture of at least two populations of electrically conductive carbon particles of different size, wherein the at least two populations of electrically conductive carbon particles are substantially uniformly mixed in the direction of a plane extending along the at least one external surface.

  • Publication number: 20040126643
    Abstract: A fuel reservoir for a liquid fuel cell particularly useful for portable electronic devices or for a reformer, includes (a) a container defining a volume for holding a liquid fuel; (b) a wicking structure positioned within the volume and into which at least one portion of the liquid fuel wicks and from which said liquid fuel subsequently may be metered, such as by pumping; (c) a retainer to hold the wicking structure in a desired orientation within the container; and (d) an outlet for the liquid fuel that is in communication with the wicking structure. A method of dispensing liquid fuel and a method of assembling a fuel cartridge are also disclosed.
