摘要： Körper aus expandiertem Graphit werden mit niedrigviskosen, lösungs-mittelfreien, lagerstabilen, polymerisierenden Harzen aus der Gruppe der Isocyante und deren Reaktionspartner und/oder Epoxidharze bis zu Harzgehalten von 50 Gew.-% imprägniert. Um das zu ermöglichen, verwendet man ein Vorprodukt aus expandiertem Graphit mit offenem Porensystem, mit einem besonders bevorzugten Bereich von Rohdichten von 0,5 bis 1,3 g/cm 3 und mit einem Aschewert von höchstens 4 Gew.-%. Solche Körper können anteilig auch Zuschlagstoffe enthalten. Die imprägnierten, geformten und rasch härtbaren Graphitkörper werden als Dichtungselemente, als Komponenten in Brennstoffzellen oder als Wärmeleitelemente eingesetzt.

摘要： Flexible graphite sheet is made by compressing a mixture of fine particle of intercalated, exfoliated, expanded natural graphite with fine particles of intercalated, unexpanded, expandable particles of natural graphite admixed with small amounts of a phosphorous bearing compound, the unexpanded particles being more finely sized than the expanded particles. The resulting sheet of flexible graphite exhibits improved fire retardant and sealability properties and additionally resistance to oxidation and corrosion.

摘要： Methods of making a graphite material are provided. A flexible graphite is ground into a powder. The graphite powder is mixed with a resin and the mixture is hot pressed. A second method of making a graphite material is provided where the graphite is ground into a powder; the graphite powder is soaked in a cryogenic liquid; the soaked graphite powder is then expanded; the expanded soaked graphite powder is mixed with a graphite powder; and the graphite powder mixed with a resin are hot pressed. According to a third method, the flexible graphite is ground into a powder; the graphite powder is soaked into a cryogenic liquid, the soaked graphite powder is expanded; and the expanded soaked graphic powder is ground into a fine powder. The resulting graphite powder is mixed with a resin. The graphite powder mixed with the resin is hot pressed. According to a fourth method, graphite flakes are soaked into an acid; the soaked graphite flakes are expanded; and the expanded soaked graphite flakes are precompacted. The precompacted soaked graphite flakes are ground into a powder. The ground precompacted expanded soaked graphite powder is then mixed with a resin. The graphite powder with the resin is hot pressed.

摘要： A separator for fuel cells of solid polyelectrolyte type which overcomes the disadvantages of the prior art, is lightweight, can be slotted easily, and exhibits high gas barrier properties; and processes for the production thereof. The separator is of the type to be sandwiched between gas diffusion electrodes of the fuel cell and characterized by being made of the carbonaceous composite material comprising expanded graphite particles which have a mean particle diameter of 5 to 12 mu m and at least 80 % of which have diameters falling within the range of 0.1 to 20 mu m and a thermoplastic or thermosetting resin or a sinter thereof, wherein the graphite particles are dispersed in the resin of sinter thereof, and having slots for feeding oxidant gas or fuel gas on one or both surfaces thereof. The separator can be produced by mixing a thermoplastic or thermosetting resin with the above-specified expanded graphite particles, pressure-molding the obtained mixture at ordinary temperature to 400 DEG C and forming slots of feeding oxidant gas or fuel gas on one or both surfaces of the resulting carbonaceous composite material, or by mixing a thermosetting resin with the above graphite particles, pressure-molding the obtained mixture at ordinary temperature to 400 DEG C, firing the resulting molding in a nonoxidizing atmosphere at 700 to 3000 DEG C to form a carbonaceous composite material, and forming slots for feeding oxidant gas or fuel gas on one or both surfaces of the material, or by mixing a thermosetting resin with the above graphite particles, pressure-molding the obtained mixture at ordinary temperature to 400 DEG C, forming slots for feeding oxidant gas or fuel gas on one or both surfaces of the obtained molding, and firing the resulting slotted molding in a nonoxidizing atmosphere at 700 to 3000 DEG C.
