  • Publication number: 20080220163
    Abstract: A metal oxide is synthesized in the pores of a porous catalyst base material by impregnating a raw material solution for synthesis of that metal oxide into those pores. At that time, mesh-like cracks are formed in the metal oxide support layer coated onto the inner surfaces of the pores by adjusting the solid portion concentration in the raw material solution for synthesizing the metal oxide to a suitable value. In addition, fine pores are formed in the metal oxide support layer obtained after firing by containing a polymer and so forth in the raw material solution for synthesizing the metal oxide. The presence of these mesh-like cracks and/or fine pores in the metal oxide support layer allow the obtaining of effects such as greater ease of diffusion of exhaust gas into this support layer.

    Abstract: The present invention provides a continuous process for producing catalyst-coated polymeric electrolyte membranes and membrane electrode assemblies for fuel cells. The process of the invention uses an ionomer membrane having a polymeric backing film on the back side. After the first coating step, the membrane is dried, during which the residual solvent may be almost completely removed. After this, the polymeric backing film is removed and the back side of the membrane is coated in a second step. The front and back sides of the membrane can be coated by various methods, such as screen printing or stencil printing. Two gas distribution layers are applied to the two sides of the catalyst-coated membrane to produce a 5-layer membrane electrode assembly. The membrane electrode assemblies are used in polymeric electrolyte membrane fuel cells and in direct methanol fuel cells.

While still in contact with the pattern member, the sheet is heated or otherwise treated to cause evaporation of the water from the sheet. Evaporation while in contact with the pattern member takes place in such a way that hydrophobic polymer is concentrated in the sheet at the openings of the pattern member by the process of evaporation.

  • Patent number: 7157115
    Abstract: Porous polymers are made by adding biologically active agent and growth substrates (e.g., yeast and sugar, preferably in the presence of water or other suitable fluid) to a polymer forming material, which may be a liquid. The yeast acts on the sugar, forming carbon dioxide gas bubbles. The material is then polymerized so that the gas bubbles create permanent pores within the polymeric material. The polymer can be an epoxy for example. The pores will contain residue of the yeast. Also, porous metals can be made by combining a metal powder with yeast, sugar, and water. The porous metal paste is then sintered. Porous ceramics and semiconductors can be made by combining the yeast and sugar with a ceramic forming liquid such as polysilazane. Polysilazane converts to silica when heated, which helps to bind the ceramic or semiconductor powder particles at a reduced temperature. Biological agents other than yeast (e.g. bacteria, enzymes), and growth substrates other than sugar can also be used.

  • Patent number: 7078361
    Abstract: This invention is an improved fuel cell design for use at low pressure. The invention has a reduced number of component parts to reduce fabrication costs, as well as a simpler design that permits the size of the system to be reduced at the same time as performance is being improved. In the present design, an adjacent anode and cathode pair are fabricated using a common conductive element, with that conductive element serving to conduct the current from one cell to the adjacent one. This produces a small and simple system suitable for operating with gas fuels or alternatively directly with liquid fuels, such as methanol, dimethoxymethane, or trimethoxymethane. The use of these liquid fuels permits the storage of more energy in less volume while at the same time eliminating the need for handling compressed gases which further simplifies the fuel cell system.

    Abstract: Porous coatings on high-performance ceramics attempt to combine the mechanical and thermal characteristics, which fulfil stringent demands, of the substrate material with the advantageous properties of coating materials. The subsequent application of layers of this type to the pre-sintered substrate produces unsatisfactory results in several areas of use with regard to possible layer thickness, porosity and adhesion. According to the invention, a shaped body consisting of a sintered, inorganic material, whose surface comprises a porous layer is produced in such a way that the base body is first formed as a green body. A layer in the form of a suspension, also containing an inorganic material, is then applied to the surface or to one section of the surface of the base body. A predetermined fraction of a pore-forming substance is mixed with at least the material of said layer and the green body with its applied layer is subjected to the thermal treatments required for producing a monolithic sintered body.

A coating comprising porous polyimide resin is formed by applying resin solution comprising a precursor of polyimide resin and a dispersive compound and then drying a solvent, to form a coating in which the dispersive compound is dispersed in the precursor of polyimide resin; extracting the dispersive compound from the coating for removal to make the precursor of the polyimide resin porous; and imidizing the coating after preheated in a temperature range of 190–250° C.

  • Patent number: 6977095
    Abstract: A process for producing a rigid reticulated article involves coating a reticulated substrate which has open, interconnected porosity with a first dispersion comprising a ceramic or metal powder to form a first coating thereon; drying the coated reticulated substrate; contacting the coated reticulated substrate with one or more additional dispersions in succession to form one or more additional coatings thereon; drying the additional coatings between the steps of contacting; heating the coated reticulated substrate to pyrolyze organic components; and sintering the coated reticulated substrate to form a reticulated article, wherein each dispersion has a viscosity less than that of all preceding dispersions. A rigid reticulated article includes inner, intermediate and outer sintered layers of material in which the inner and outer layers are of different composition and the intermediate layer is a composite of the inner and outer layers.

  • Patent number: 6953603
    Abstract: The invention concerns a method for producing porous ceramic layers on metallic, ceramic, enameled or glass substrates using crystalline nanoparticles of particle sizes of between 3 nm and 100 nm via a wet-chemical process and functionalising of this porous ceramic layer through introducing a second component into the pores of the porous ceramic layer which serves as carrier layer. The porous ceramic layers can be filled with hydrophobizing, hydrophilizing, dirt-repellent and corrosion-inhibiting substances which remain in the substrate or are supplied later on demand, or with bactericidal substances, aromatics, perfumes or inhalation substances which are delivered to the room air in precise doses.

  • Patent number: 6919106
    Abstract: A porous SOG film is formed by preparing an organic silane solution containing an organic silane, water and an alcohol, subjecting the organic silane to acid hydrolysis or alkali hydrolysis and then heat-treating the resulting reaction system in the presence of a surfactant to thus form a porous SiO2 film to use for an interlayer insulating film. Alternatively, a porous SOG film is formed by repeating the foregoing step at least one time; or by forming a hydrophobic film on the porous SiO2 film prepared by the foregoing step by the CVD or sputtering technique to thus cap the surface of the porous film; or repeating the porous film-forming and capping steps at least one time. Moreover, after the preparation of the foregoing porous SiO2 film, it is subjected to either of the oxygen plasma-treatment, electron beam-irradiation treatment and UV light-irradiation treatment to remove the unreacted OH groups remaining on the porous film and to thus form a porous SOG film.

  • Patent number: 6908641
    Abstract: The present invention relates to an improved doctor blade and bedplate apparatus wherein there is a recess in the bedplate from some position upstream of the doctor blade to some position downstream of the doctor blade. This recess or gap in the area of the bedplate under the doctor blade allows one to form an even or uniform coating on the back of a web of material. This is particularly helpful in forming uniform coatings on the back of a greige good which has face fibers of varying lengths. The present invention also relates to an improved process for preparing a relatively uniform coating on the back of a web of material.
