The present invention relates to a working machine having an engine room and a housing, wherein the housing at least partially surrounds or can surround the engine room, wherein a venting space, in which a line mouth of a line ends, is arranged on the housing, wherein the venting space is delimited from the engine room, preferably delimited in a gas-tight manner, and wherein the venting space is formed by a partial region of the housing and a bottom piece arranged in the engine room.

A fuel cell vehicle includes a cabin arranged at a vehicle front portion and provided with a seat therein where an occupant is seated, a fuel cell mounted below the cabin, and an accommodation space formed below the cabin and accommodating the fuel cell. An upper side of the accommodation space is covered with a ceiling surface formed by a bottom portion of the cabin, and a rear side of the accommodation space is opened. The ceiling surface is provided with a detector configured to detect a hydrogen concentration in the accommodation space.

A midfloor module (10, 11) for a motor vehicle has a frame structure (10) with a battery frame (10). The battery frame (10) has multiple battery modules (11), and multiple tank volumes (1, 2, 2+) that can be used optionally for fuel. A motor vehicle that is equipped with such a midfloor module (10, 11) also is provided as well as a method for manufacturing the midfloor module (10,11).

The present disclosure generally relates to modular fuel cell systems that provide power, air handling, and/or cooling systems to create a hybrid or electric vehicle.

A system is provided for estimating the time required for a vehicle to visit a fueling station. The system includes a fueling station server associated with the fueling station and configured to transmit, over a network, a plurality of fueling station parameters. The system also includes sensors within the vehicle; a navigation system configured to provide navigation data; and a non-transitory memory storing fuel tank parameters for the vehicle. The system also includes a processor within the vehicle configured to: based on the navigation data, determine a travel time required for the vehicle to reach the fueling station; based on the fueling station parameters, sensor data, and the fuel tank parameters, compute a fueling time required for the fueling station to fill the fuel tank; and compute a total time requirement, including the travel time and the fueling time.

The present disclosure provides a mining haul truck with the diesel-powered components removed, the resulting available volumes retrofitted with components of a hybrid hydrogen fuel cell / battery-based powerplant. In some embodiments, the tray and/or the canopy of the haul truck can be replaced or reconfigured to create an additional volume for receiving components of the hybrid hydrogen fuel cell / battery-based powerplant.

A pressure vessel arrangement has a pressure vessel for storing a gaseous fuel and a conducting arrangement arranged adjacent to the pressure vessel for conducting and weakening a shock wave occurring upon bursting of the pressure vessel. The conducting arrangement forms a chamber space that can be expanded by the shock wave. The conducting arrangement has an inlet into the space facing the pressure vessel, via which the shock wave enters the space and expands the space, and wherein the conducting arrangement has at least one outlet out of the space, via which the shock wave exits the space into the environment.

A conveying device for a fuel cell system for conveying and/or recirculating a gaseous medium, in particular hydrogen, includes a recirculation fan, a jet pump that is driven by a motive stream of a gaseous medium that is under pressure, and a metering valve. The gaseous medium is supplied to the jet pump by the metering valve. The conveying device further includes an inlet fluidically connected to an anode outlet of the fuel cell and an outlet fluidically connected to an anode inlet of the fuel cell. The jet pump and the metering valve form a combined valve/jet-pump assembly. The components of the conveying device are positioned on a planar carrier element such that flow lines between and/or within the components extend only parallel to the planar carrier element. The planar carrier element is arranged between the fuel cell and the conveying device.

A gas supply system includes: high-pressure tanks having at least different longitudinal lengths; supply pipes each connected to corresponding one of the high-pressure tanks; a supply-side manifold to which the supply pipes are connected; solenoid valves disposed in the respective supply pipes; a first pressure sensor configured to acquire a pressure related to an internal pressure of the high-pressure tanks; a second pressure sensor configured to acquire a pressure at the supply-side manifold; and a control device that controls the solenoid valve corresponding to the high-pressure tank, among the high-pressure tanks, having the largest ratio of the longitudinal length to a short-side width, to open first when a value obtained by subtracting the pressure detected by the second pressure sensor from the pressure detected by the first pressure sensor is larger than a threshold at the time of activation of the gas supply system.

The mobile foundation for tower cranes and fast-erecting cranes comprises at least two floor elements made from metal, which may be releasably connected to one another, in particular screwed to one another, wherein the floor elements have anchoring devices for a crane tower. Transportable, reusable ballast weights may be supported on at least one support surface of the foundation. There is provided a passage element having uprights and/or side walls, wherein the uprights or side walls, respectively, have a height of at least 2.1 m, preferably of at least 2.3 m, wherein the passage element may be releasably connected to the floor elements, in particular screwed thereto.
