  • Publication number: 20150180051
    Abstract: A fuel cell module includes at least one fuel cell stack with a housing. The at least one fuel cell stack is arranged, with a plurality of system components for conducting and/or conditioning the fluids for the supply of the at least one fuel cell stack, with a mechanical interface for fastening the fuel cell module to the vehicle. The mechanical interface is arranged on the housing, wherein the housing forms a carrier for the system components.

  • Publication number: 20150086886
    Abstract: A fuel cell stack arrangement includes a fuel cells arranged between a first and a second end plate. At least one of the end plates is designed as a channel end plate with at least one channel. The channel has a stack opening, which is opened in the direction of the stack, and a second opening. The stack opening and the second opening are connected to each other via a channel section and are arranged at a distance to each other in a top view looking down on the channel end plate.

  • Patent number: 7963017
    Abstract: The method is used for automated tightening of a screwed joint (16), which is fitted to a component (10) in advance and contains a screw (12) and a nut (14), using a programmable industrial robot system (18). In this case, the invention provides that the industrial robot system (18) has a first robot (20) with a screw driving head (22) and a second robot (24) with a mating holding head (26). In order to tighten the screwed joint (16) on the component (10), the screw driving head (22) is positioned in a defined screw driving position, and the mating holding head (26) is positioned in a defined mating holding position in order to produce an interlocking connection, which is suitable for tightening of the screwed joint (16), between the mating holding head (26) and the nut (14), as well as between the screw driving head (22) and the screw (12). The screwed joint (16) on the component (10) is tightened with a predeterminable fixing torque. The interlocking connections are then disconnected.

  • Patent number: 6862801
    Abstract: A receptacle having an end cap, a pliable sidewall, and a fastener, for receiving and retaining a fuel cell stack in its stacked configuration during fabrication of a multi-stack fuel cell assembly, is shown and described. Methods of fabricating the assembly include stacking the fuel cell in the receptacle, compressing the fuel cell, and engaging the fastener to retain the stack in its stacked configuration and, or to retain the stack under at least partial compression.

  • Publication number: 20050011564
    Abstract: The invention relates to a control plate of an automatic gearbox, which plate comprises two housing parts and a steel sealing plate clamped in between in a sealing manner by means of screws. In order to keep the manufacturing spread of the tightening torque of these screws small, the screws are tightened until beyond their RP 0.2 limit in a manner controlled by the angle of rotation.
