20110174052 | HYDROGEN SENSOR ASSEMBLY - A hydrogen sensor assembly is disclosed. The hydrogen sensor assembly includes a sensing element within a sensor housing. The sensor housing includes an opening to facilitate a fluid communication between the sensing element and an exhaust stream of a fuel cell. A substantially water-vapor-impermeable membrane is disposed within the opening between the sensing element and the exhaust stream to militate against water vapor from the exhaust stream entering the sensor housing. The sensor housing may include a second opening to facilitate a fluid communication between the sensing element and an external environment to evacuate water vapor generated by the sensing element. | 07-21-2011 |
20110302993 | FUNCTION TEST OF FUEL CELL EXHAUST GAS STREAM HYDROGEN SENSOR BY GENERATING DEFINED HYDROGEN PULSES WHILE DRIVING AND AT REGULAR SERVICE WITH FUEL CELL SYSTEM IMMANENT DEVICES - A system and method for determining whether a hydrogen concentration sensor in the exhaust of a fuel cell system is operating properly during operation of the system. The method includes injecting hydrogen gas pulses from an injector directly into the system exhaust and analyzing a sensor response from those hydrogen injection pulses. Alternately, pulses from anode purges or bleeds can be provided to the exhaust to determine sensor response. | 12-15-2011 |
20110303017 | INTEGRATION OF STRAIN GAUGES AT INNER- AND OUTER LINER OF A HIGH PRESSURE TANK TO INDICATE DISCHARGE LIMIT POINT - A high pressure tank that has particular application for storing hydrogen gas on a vehicle for a fuel cell system. The tank includes a gas tight inner liner layer and a fiber bundle outer composite structural layer. A first strain gauge is provided in the outer layer and a second strain gauge is provided in the inner liner layer both proximate a transition between the layers. The strain gauges are calibrated relative to each other to identify the pressure where the inner liner layer begins to shrink and separate from the outer composite layer. | 12-15-2011 |
20120228869 | LEAK-TIGHT CONNECTION BETWEEN PIPE AND PORT - A method of forming a leak tight connection between a pipe and a port made of different metals is described. A leak tight connection between a pipe made of a first metal and a port made of a second metal is also described. | 09-13-2012 |

20100265744 | POWER SEMICONDUCTOR MODULE - A power semiconductor module includes at least two power semiconductor units that are interconnected and that have controllable semiconductors. Each semiconductor unit is associated with a cooling plate to which the semiconductors are connected in a heat-conducting manner. The object is to provide a semiconductor module that is compact and cost-effective and at the same time explosion-proof. The power semiconductor module of the invention has a module housing which houses the power semiconductor units. The cooling plates form at least part of the module housing. | 10-21-2010 |
20110226740 | VACUUM SWITCH HAVING FIXED RAIL TERMINALS ON BOTH SIDES - The vacuum switch is compact, requires little effort, and provides a reliable current path having a high current-carrying capacity between the terminals of the vacuum switch, particularly at high switch-on speeds. The vacuum switch has a vacuum chamber, in which a vacuum is present and in which a switching contact is arranged. The switching contact includes a fixed contact piece firmly connected to the vacuum chamber and in electrical contact with a fixed contact terminal, and a moving contact piece movably guided relative to the fixed contact piece. The moving contact piece is at a distance to the fixed contact piece in a disconnect position and contacts the latter in a contact position. A drive unit produces a drive movement. A switching mechanism is connected to the drive unit and the moving contact piece and includes a conductor section that is electrically conducting up to the moving contact piece. A connector connects a moving contact terminal electrically to the moving contact piece in the contact position. The connector has a clamping contact, which has an insertion clamping contact piece connected to the conductor section of the switching mechanism and a mating clamping contact piece firmly connected to the vacuum chamber and electrically connected to the moving contact terminal. The insertion clamping contact piece and the mating clamping contact piece are arranged relative to each other such that the insertion clamping contact piece is clamped with the mating clamping contact piece in an electrically conducting manner as a result of the drive movement. | 09-22-2011 |
