Abstract: An air supply device for a fuel cell system having an electrically driven flow compressor with an electric motor driving a shaft includes first and second compressors independently controllably coupled to the shaft by respective coupling devices. The first compressor has a feed line from which a feed bypass line branches off at a branch point and opens to an inlet side of the second compressor with a control element arranged in the branch, and with the first compressor having a compressor outlet that opens into a compressor outlet line that is connectable to the feed bypass line via a connection line controllable by means of a control unit. The compressors may be operated individually or together with flow arranged in parallel or in sequence when operating together, and may have different operating maps and mass airflow capabilities.

Abstract: A charging device for a primary vehicle configured for charging a secondary vehicle comprises at least one repositionable coupling element. The at least one coupling element is repositionable such that it can be positioned correspondingly in relation to a coupling element of a charging device of the secondary vehicle. The charging device is set up to ensure an inductive charging process between the primary vehicle and the secondary vehicle using the coupling element.

Abstract: A method for producing a compressed gas tank for a motor vehicle includes inserting a bundle of heat-conducting elements through an opening in a housing of the compressed gas tank and exerting a force on the bundle that radially expands the bundle within the housing beyond the size of the opening. The heat-conducting elements may be helically wound about a central axis when inserted through the opening with a torsional force applied to unwind the elements while radially expanding and reducing axial length of the bundle. A compressed gas tank for a motor vehicle includes a plurality of heat-conducting elements including at least one tube within a tank housing that extend axially along the tank and radially within the housing to a size exceeding an opening of the housing. The tube is configured to circulate coolant to cool compressed gas within the tank.

Abstract: A pressurized gas tank for a motor vehicle includes a cylindrical axially extending housing with two end pieces axially connected thereto connected together by one or more tie rods configured for axial transmission of tensile force. The tie rods include an axially continuous through-channel configured to be connected to a vehicle cooling system including a circulating liquid coolant to cool the pressurized gas at least during refueling of the pressurized gas tank.

Abstract: A fuel cell vehicle and associated fluid line arrangement include a main branch, which passes through a fuel cell unit, and a secondary branch that branches off the main branch and includes a flow limiter having a tube element, the internal cross section of which decreases downstream with respect to a flow direction, and a piston element moveable at least partially downstream along a movement path in the tube element counter to a restoring force between an open position and a restricting position. The flow limiter provides a fluid-carrying cross section of passage that is smaller than in the open position formed between the piston element and the tube element to limit mass flow through the secondary branch between a maximum and minimum mass flow.

Abstract: A hydrogen fuel cell vehicle system and method inhibit formation of black ice on road surfaces at low temperatures as a result of exhaust water by treating the exhaust water prior to discharge with a deicing or antifreeze substance to lower the freezing point of the water. A metering device may meter a deicing or antifreeze substance, such as sodium chloride, calcium chloride, urea, or the like to be dissolved in the exhaust water that is produced during the production of energy. The vehicle may include a bypass valve that selectively bypasses the water treatment system when ambient conditions are not conducive to ice formation. The bypass valve is operated to direct exhaust flow to a condenser and water treatment system when ambient conditions are favorable to ice formation, with the deicing or antifreeze substance metered based on current or predicted ambient or road surface conditions.
