Patent number: 8497035Abstract: A battery cell for an electric vehicle battery pack, including surface-applied wires to facilitate connecting the cell to a controller. Resistive or non-resistive wiring is printed onto or otherwise applied to the outer surface of the battery cell, to eliminate the need for separate jumper wires routed around or through the battery pack. A surface-applied wire is directly connected to each terminal of the battery cell, and each wire is routed on the outer surface of the cell to a location convenient for connecting a cell monitoring controller. The surface-applied wires can be made of a suitable resistive material, such that the resistance of each wire is known and the wires can be used for dissipating power during cell state of charge equalization. An insulating layer can be applied over the surface-applied wire to minimize the risk of short circuit.Type: GrantFiled: June 23, 2010Date of Patent: July 30, 2013Assignee: GM Global Technology Operations LLCInventors: Manfred Herrmann, Hartmut Stengelin, Peter Andres

Patent number: 8431282Abstract: A fuel cell system that employs a closed coolant loop. The system includes an expansion device having a flexible membrane, where a cooling fluid side of the membrane is in fluid communication with the cooling fluid in the coolant loop and an air side of the membrane is in communication with an air pocket. The air side of the expansion device is in air communication with an air compressor so that the pressure of the cooling fluid within the coolant loop changes as the stack pressure changes. The fuel cell system also includes a coolant reservoir that is in fluid communication with the cooling fluid in the coolant loop. Air and hydrogen bubbles within the cooling fluid are vented to the coolant reservoir where they accumulate. The coolant reservoir includes a level sensor indicating the level of the cooling fluid therein.Type: GrantFiled: April 13, 2007Date of Patent: April 30, 2013Assignee: GM Global Technology Operations LLCInventor: Manfred Herrmann

Publication number: 20120291641Abstract: A cylinder of a printing press is supported by bearings in side frames of the printing press. An inner ring of a radial bearing serves a journal of the cylinder which is arranged directly over a bearing agent in an outer ring thus enabling a radial movement of the journal. The outer ring is mounted, either directly or indirectly in an opening of the side frame. The radial bearing is arranged in a region of the outer ring, as viewed in an axial direction of the cylinder, which protrudes out of a frame alignment of the side frame toward the side of the cylinder. The bearing agent which enables radial movement of the cylinder is also arranged in a region of the outer ring protruding out of the frame alignment of the side frame toward the side of the cylinder.Type: ApplicationFiled: October 11, 2010Publication date: November 22, 2012Applicant: KOENIG & BAUER AKTIENGESELLSCHAFTInventor: Manfred Herrmann Liebler

Patent number: 7767325Abstract: A method and an apparatus for the investigation of a fuel cell system comprising at least one fuel cell having an anode side to which a fuel is supplied in operation and a cathode side which is separated from the anode side by a membrane and to which an oxidizing agent is supplied in operation, in order to carry out at least one of the following tests: a) to test whether the fuel cell system is gas-tight at the anode side and/or at the cathode side, b) to test whether a leakage is present between the anode side and the cathode side of the fuel cell system, c) to test the starting behavior of the fuel cell system, d) to test the operation of the fuel cell system at low current yield. The respective test is carried out with a mixture of at least inert gas with at least one fuel permissible for the operation of the fuel cells, the mixture being supplied to the anode side of the fuel cell system.
