Abstract: A gas diffusion layer contains a substrate formed of a carbon containing material and a micro porous layer. The gas diffusion layer can be obtained by dispersing carbon black with a BET surface area of at most 200 m2/g, carbon nanotubes with a BET surface area of at least 200 m2/g and with an average outer diameter of at most 25 nm and a dispersion medium at a shearing rate of at least 1,000 seconds?1 and/or such that, in the dispersion produced, at least 90% of all carbon nanotubes have a mean agglomerate size of at most 25 ?m. The dispersion is applied to at least one portion of at least one side of the substrate, and the dispersion is dried.

Abstract: A carbon-fiber-based gas diffusion layer (GDL) for use in polymer electrolyte membrane (PEM) fuel cells (FC) having structured hydrophilic properties, wherein materials with hydrophilic properties and selected from the group of metal oxides in an average domain size of 0.5 to 80 ?m are present as hydrophilic wicks in the gas diffusion layer.

Abstract: An edible protein-containing meal for human and animal consumption and high quality food grade oils are obtained from oil seeds and other oil and protein containing plants. The meal has a significantly improved level of dietary available (absorbable) protein. The protein is substantially free of oils and fats, and is a cleaner, purer product with high levels of absorbable protein. Such protein isolates can be used as such or added to formulated foods in order to increase the total protein content of that food. The meal produced and the oils recovered have compositions which are unique and unobtainable by prior processing methods, having a greater content of proteins, the proteins having a greater solubility and an increased ratio of high to medium molecular weight proteins.

Abstract: This invention relates to electrode substrates for electrochemical cells, particularly low-temperature fuel cells, and processes for their production. Low-cost carbon fiber paper structures are used as precursor for preparation of an all-carbon product that has a high electric conductivity and porosity and can be processed in a continuous reel-to-reel mode. These paper materials are further impregnated and processed to adjust the final product properties. This all-carbon electrode substrate is not brittle thereby avoiding the main disadvantage of the prior art.

Abstract: A crystal-pulling apparatus for pulling and growing a monocrystalline silicon ingot comprises a quartz crucible placed in a chamber and containing a silicon melt from which a monocrystalline silicon ingot will be pulled, a graphite crucible container to support the quartz crucible by surrounding the outer circumferential surface and external base surface of crucible, and a heater provided around the outer circumferential surface of the crucible container to heat the silicon melt. This apparatus further comprises a spacer having a top surface whose area is smaller than the base area of the quartz crucible and having a melting point higher than that of silicon, is inserted between the base of the quartz crucible and the base of the crucible container while the monocrystalline silicon ingot is pulled.

Abstract: This invention relates to electrode substrates for electrochemical cells, particularly low-temperature fuel cells, and processes for their production. Graphitized fiber web structures are used that have a preferred non-planar fiber alignment resulting in high through-plane conductivity. These structures are further impregnated and processed to adjust the final product properties.
