    Abstract: A filter contains fluent particulate, such as carbon granules. The filter is divided into a plurality of cell chambers by walls, including an upper wall. The upper wall has a surface that faces, and is closest to, the top surface of the particles. The upper wall surface is oriented so that, as the particles settle, any gap formed between the top surface of the particles and a portion of the upper wall surface will not extend from the upstream to the downstream sides of the filter. Instead, contact is maintained between the top surface of the particles and the upper wall surface during fluid flow through the filter, and therefore any gas flowing through the frame must flow through, and through spaces around, particles. An angle between the upper wall surface and the flow direction of gas striking the filter is greater than about three degrees.

  • Patent number: 8882874
    Abstract: A unique, multi-cartridge, easily re-configurable ambient air filter assembly (air contaminant control system) that removes particulate and gaseous chemical/biological contaminants from the incoming cathode air stream on a fuel cell or similar devices is described. The filter assembly is composed of individual filter cartridges (sub-assemblies) of various filtration media that are targeted at removing specific airborne contaminants. Combining specific sets of cartridges enables the filter assembly to be readily/rapidly configured (and re-configured) for specific applications—such as urban, rural, industrial, or military battlefield environments. Selection of correct media ensures complete removal of potential contaminants, enables rapid re-configuration to different environments, quick replacement of spent cartridges without disposal of non-spent media (reducing waste and cost).
