    Abstract: A method for at least partially compensating for a temperature-induced rise in pressure in a fuel-cell system includes providing a fuel-cell system that has an anode supply path that establishes a fluidic connection between a fuel-cell stack and at least one fuel-source, and an anode-side stack shut-off valve in the anode supply path, the anode-side stack shut-off valve prohibiting the supply of fuel to the fuel-cell stack from an anode section of the anode supply path. The fuel-cell system also has an excess-pressure valve in the anode section, the excess-pressure valve conducting fuel away out of the anode section if the pressure in the anode section exceeds a tripping pressure. In the shut-down state, the pressure in the anode section rises due to warming of the fuel. The anode-side stack shut-off valve is opened to relieve the pressure before the rising pressure in the anode section reaches the tripping pressure.

    Abstract: A two-track multi-axle motor vehicle including at least two fuel tanks in which a fuel for producing driving energy for a vehicle drive unit can be stored under high pressure of the order of magnitude of 300 bar and more is provide. Each tank includes a safety valve device having a temperature-sensitive element monitoring only a partial region of the tank surface. The safety valve device allows at least a partial quantity of the stored fuel to escape from the respective tank at a higher temperature, which can occur, for example, in the case of a fire. The temperature-sensitive elements of at least two tanks are arranged here in such a manner that the distance between a left-side wheel (RL) of that vehicle axle, in the vicinity of which the at least two fuel tanks are arranged in the vehicle, and the temperature-sensitive element closest to the left-side wheel (RL) does not significantly differ from the distance of the other of the two temperature-sensitive elements from the right-side wheel (RR) of the vehicle axle.

    Abstract: A method is provided for filling a fuel storage system of a motor vehicle with fuel at a relatively high pressure. The fuel storage system has a main tank, which can be filled by way of a main filling line until a limit pressure has been reached, and an auxiliary storage device. If the filling line is connected to a supply station, which provides fuel at a pressure exceeding the tank limit pressure, a tank shut-off valve provided in the filling line will be closed in time before the limit pressure is reached in the main tank and an auxiliary tanking valve is opened in an auxiliary storage device filling line branching off from the main filling line upstream of the tank shut-off valve and leading to the auxiliary storage device. The auxiliary storage device is configured to receive fuel at a higher pressure than the above-mentioned tank limit pressure. The auxiliary storage device is connected downstream of a shutoff valve, which is provided in a supply line leading to a consuming device and which is closed during a filling operation of the main tank, to the supply line such that the consuming device can be operated from the auxiliary storage device even when the shut-off valve is closed.

    Abstract: A pressure vessel system for a motor vehicle has at least one pressure vessel, to which an extraction line is connected. The extraction line has a connection point, to which a connection line leading to a consumer is connected. The connection point of the extraction line includes a first coupling part of a quick coupling, to which a second coupling part of the quick coupling, arranged on the connection line, is connected. The first coupling part has a non-return valve, which closes the extraction line when the second coupling part is decoupled.
