  • Patent number: 7501008
    Abstract: The present invention relates to a gas storage and dispensing system, which comprising a carrier material for a target gas and multiple microtubular elements in contact with such carrier material. Each microtubular element comprises a tubular wall that defines a bore side and a shell side that are sealed from each other, preferably by one or more potting members. The carrier material is either at the bore sides or at the shell sides of the microtubular elements, and it can be either a solid sorbent material for the target gas, or a liquid carrier therefor. Such gas storage and dispensing system is particular useful for hydrogen storage, when the carrier material can be a hydrogen-sorbent that contains hydrogen gas, or liquefied hydrogen, or an organic hydrogen solution, or a metal hydride solution capable of generating hydrogen gas. Such microtubular elements can further be designed as microfibrous fuel cells, while each microfibrous fuel cell comprises a carrier material at its bore side.

  • Publication number: 20040058224
    Abstract: This invention relates to a microfibrous fuel cell having at least one high quality electrocatalyst layer of a dual-layer structure, i.e., a catalyst layer comprising a catalytic material, and an interfacial composition layer comprising a mixture of catalytic material and electrolyte medium. Said high quality electrocatalyst layer can be formed by various catalyzation methods, including diffusion catalyzation, ion-exchange catalyzation, electrodeposition catalyzation, impregnation catalyzation, chemical deposition catalyzation, and alternating catalyst/electrolyte addition catalyzation. The present invention also relates to a fuel cell assembly comprising multiple such microfibrous fuel cells bundled together, and methods for in situ catalyzation of such fuel cell assembly to form high quality electrocatalyst layers of such dual-layer structure.

  • Patent number: 4328901
    Abstract: A pressure vent for an explosion proof container. The vent allows a high flow rate of gases to pass from the container while arresting flames and cooling exiting hot gases therein. This precludes the build-up of high peak pressures inside the container. Structurally the vent has a protective cover mounted to the container by a knife hinge on one side and closed by imbedded magnets on the opposite side. In addition, the vent has multilayered material mounted in the same container opening near the interior of the container. A layer of porous stainless steel foam with multiple layers of stainless steel screen is used for this vital multilayered material. The optimum embodiment is obtained by preselecting a relationship between the free space volume inside the enclosed container, the number of layers in the prefilter section of the vent, and the cross sectional area of the vent.

  • Patent number: 4180177
    Abstract: A vent device for relieving pressure buildup inside an electrical enclosure due to an internal explosion of gases. A mass of stainless steel foam covers an opening in the enclosure and stops any flames or particles from escaping but provides a large equivalent cross section opening to permit the gases to escape and vent the pressure buildup. An outer cover protects the foam mass from impact damage and shields it from high pressure water spray used in cleaning. The cover is vertically hung from a knife-edge and held closed by means of a permanent magnet. A predetermined pressure differential is sufficient to overcome the attractive force of the magnet and allow the protective cover to be pushed open.
