| 20110223516 | HIGH-TEMPERATURE FUEL CELL STACK, AND PRODUCTION THEREOF - A cassette for a high-temperature fuel cell stack, comprising at least one fuel cell including an anode, a cathode, and an electrolyte, and a metal cell frame which surrounds the fuel cell peripherally, wherein the metal cell frame has two sections, these being an inner thin compensating frame that contacts the fuel cell and a thicker, rigid outer frame which is provided for contacting the interconnector. The inner compensating frame comprises a peripheral bead at room temperature, which entirely disappears at temperatures between 980° C. and 1100° C., as a result of the prevailing stresses. The bead has special relief functions. It is significant that this special function of the formed bead is exclusively achieved by way of the warping in the compensating metal sheet or the compensating film, and is formed solely by way of the joining sequence applied, which is to say only in combination with the joining process employed. In contrast, a component that already has a bead prior to the joining process would also be able to compensate for stresses, but not to the same extent as a bead produced using this joining process. | 09-15-2011 |

| 20110051494 | MEMORY HAVING TUNNEL BARRIER AND METHOD FOR WRITING AND READING INFORMATION TO AND FROM THIS MEMORY - A resistive memory comprises a tunnel barrier. The tunnel barrier is in contact with a memory material which has a memory property that can be changed by a write signal. Because of the exponential dependence of the tunnel resistance on the parameters of the tunnel barrier, a change in the memory property has a powerful effect on the tunnel resistance, whereby the information stored in the memory material can be read. A solid electrolyte (ion conductor), for example, is suitable as a memory layer, wherein the ions thereof can be moved relative to the interface with the tunnel barrier by the write signal. The memory layer, however, can also be, for example, a further tunnel barrier, the tunnel resistance of which can be changed by the write signal, for example by displacement of a metal layer present in this tunnel barrier. The invention further provides a method for storing and reading information to and from a memory. | 03-03-2011 |

| 20100187160 | METHOD FOR PURIFYING MINERAL OIL FRACTIONS AND DEVICE SUITABLE FOR CONDUCTING SAID METHOD - Disclosed is a method for reducing the organic sulfur content in a sulfur-containing liquid fuel, wherein the sulfur-containing fuel is first brought in contact with a hydrogen-containing gas in a presaturator and subsequently the hydrogen-enriched liquid fuel is brought in contact with a suitable adsorbent in a reactor. The adsorbent is able to adsorb at least part of the sulfur and/or of the sulfur compound from the fuel at the surface. The contact with the adsorbent can advantageously take place not only at higher temperatures of approximately 400° C., but also at moderate temperatures, as low as room temperature, because the use of liquid fuel ensures very good contact between the fuel and the surface of the adsorbent, and therefore ensures reduction of the sulfur content. | 07-29-2010 |

| 20090289632 | APPARATUS FOR APPLICATION OF A MAGNETIC FIELD TO A SAMPLE - Disclosed is an apparatus for application of a magnetic field to a sample, in particular an elongated sample. At least in places, the apparatus has magnetic bodies which are arranged such that they can rotate with respect to one another and have, and leave open, a common access opening for the sample. In particular, this allows the apparatus to be applied to an elongated sample whose ends are not accessible. As a result of the bodies being arranged such that they can rotate with respect to one another, the magnetic fields of the bodies can be adjusted with respect to one another before the apparatus is opened and closed, so as to minimize the magnetic field in the common access opening. In consequence, only small magnetic interaction forces need be overcome during opening and closing. | 11-26-2009 |
| 20090268969 | METHOD AND ELECTRON MICROSCOPE FOR MEASURING THE SIMILARITY OF TWO-DIMENSIONAL IMAGES - Disclosed is a method for measuring the similarity of two-dimensional images, at least one image exhibiting an additional signal, the location dependence or symmetry properties of which are known at least approximately. The images are partitioned into mutually identical subimages such that the extension of at least one subimage in the direction of the gradient of the additional signal is smaller than the extension of this subimage in the direction perpendicular thereto. The subimages are compared separately, and the results of all comparisons are combined to form the measurement result for similarity. As a result, the method becomes insensitive to variations in the additional signal. The method is particularly suited for the determination of defocusing and astigmatism of an electron-microscopic image. For this purpose, it is important to compare the similarity of an experimentally measured image to simulated images, which were generated using defined defocusing and astigmatism values. | 10-29-2009 |
| 20090253020 | Interconnector for a fuel cell stack and method for production - An interconnector is made of ferritic chromium steel, on which a cupriferous layer is disposed. This layer prevents interdiffusion between the chromium steel and additional components with which the interconnector has direct contact. According to the state of the art, such diffusion occurs particularly if these additional components contain nickel. In addition, the interconnector may comprise a chromium-containing oxide layer as a barrier against interdiffusion. For this purpose, the interconnector steel can also be preoxidized before applying the cupriferous layer. The interconnector has a significantly longer service life than interconnectors according to the state of the art, and it has improved electrical conductivity because the electrical contact surface thereof is free of oxides and has high transverse conductivity. | 10-08-2009 |

Said device also comprises a combustion part which comprises an inlet for an anode residual gas from a fuel cell, an inlet for an oxidation agent, a catalytic surface and a second and a third heat exchanger. The reformer part and the combustion part are connected via lines which are used to guide a water vapour/catrier gas mixture and for directing the reformat. According to the inventive method for producing a product gas which is rich in hydrogen, a first mixing chamber guides a water vapour/carrier gas mixture via a line and a fuel/oxidation agent mixture via a nozzle. The fuelwater vapour/oxidation agent/carrier gas mixture is catalytically converted into a product gas which is rich in hydrogen in exothermic and endothermic reactions. The anode residual gas from the fuel cell is catalytically converted in exothermic reactions into waste gas having few harmful substances. The heat required for evaporating water into water vapour in the water vapour/carrier gas mixture is partially produced by cooling the product gas which is rich in hydrogen and partially by cooling the waste gas of the combustion which contains few harmful substances. | 05-28-2009 |
| 20080292569 | Method for Improving Efficacy of Surfactants Prevention of Lamellar Mesophases Temperature Stabilization of the Single Phase Region and a Method for Reducing Boundary Surface Tension in Micro-Emulsions Containing Silicone Oils by Means of Additives and Surfactant/Oil Mixtures - Disclosed is a method for improving efficacy of surfactants, prevention of lamellar mesophases, temperature stabilization of the single phase region and a method for reducing boundary surface tension in micro-emulsions containing silicone oils by means of additives and a surfactant/oil mixture.

Reoxidation causes the volume of the nickel in the anode to change. The resultant mechanical stresses may destroy the gas-impermeable electrolyte. The invention provides oxygen scavengers that can be produced at low cost for the anode, which more effectively bind the oxygen that penetrates on the fuel gas side than oxygen scavengers according to the prior art. | 09-11-2008 |
