Abstract:
The invention relates to a fuel reservoir for gaseous fuel in a vehicle, in particular a sorption reservoir. The fuel reservoir is delimited by at least one wall and includes a sorption material that is contained in its interior. The fuel reservoir has a tank inlet valve containing a shut-off valve and a throttle restriction valve. The restriction of the gaseous fuel takes place inside the fuel reservoir.
Abstract:
The present invention relates to a gas pressure container having a minimum volume of 1 m3 and a prescribed maximum filling pressure for the uptake, storage and delivery of a fuel gas which is gaseous under storage conditions and is suitable for powering a vehicle by combustion of the fuel gas, wherein the gas pressure vessel has a filter through which the fuel gas can flow at least during uptake or during delivery, with the filter being suitable for removing possible impurities in the fuel gas from the stream and the impurities being able to reduce the storage capacity for the fuel gas of an adsorbent used for the storage of the fuel gas.The invention further relates to the use of such a gas pressure container for filling a further gas pressure container which is present in or on a vehicle and comprises an adsorbent for the storage of the fuel gas.
Abstract:
An apparatus for converting energy can be operated with gaseous fuel, in particular a fuel cell assembly with a fuel cell, a fuel reservoir, and consumers, adjusters, sensors, and a monitoring unit. The monitoring unit ascertains consumption by the fuel cell and/or monitors components required for its operation.
Abstract:
An accumulator for passenger cars or commercial vehicles, including a device for storing electric energy, two electric connecting devices, in particular connecting contacts, for electrically connecting the device for storing electric energy to an electric drive motor, provides a financial incentive for the user for moderate handling of the accumulator. Such a task is achieved in that at least one sensor is configured for detecting measurement data in regard to the electric current and/or the electric voltage of the accumulator taken from and/or fed to the accumulator and/or the temperature of the accumulator and/or the installation time and/or the electric current time of the accumulator.
Abstract:
The invention relates to a method for controlling the withdrawal of gas from a sorption reservoir. The temperature in the sorption reservoir having a decreasing amount of gas therein is increased until a maximum acceptable temperature is reached such that a predetermined minimum pressure in the sorption reservoir does not fall below that threshold. The invention also relates to a device for storing at least one gas, having a sorption reservoir that has at least one attachment via which the sorption reservoir can be filled with gas or via which gas can be withdrawn from the sorption reservoir. The invention also relates to a device having at least one heating element which can warm the sorption reservoir, also a control system that can increase the temperature in the sorption reservoir when withdrawing the gas in such a manner that a predetermined minimum temperature in the sorption reservoir is not fallen below in order to attain a maximum acceptable pressure.
Abstract:
The invention describes an apparatus for converting energy that can be operated with gaseous fuel, in particular a fuel cell assembly with a fuel cell (2), a fuel reservoir, and consumers (6), adjusters, sensors, and a monitoring unit. The object of the invention is to monitor the operation of the apparatus from the standpoint of safety. A monitoring unit (3) is provided for ascertaining consumption by the fuel cell (2) and/or for monitoring components required for its operation.
Abstract:
An apparatus for controlling a fuel cell device for energy supply in a finished end product has a control unit for an operation of the fuel cell device, the control unit being formed so as to control control operational points in predetermined phases during the operation and to obtain an adjustable value of at least one device variable of the fuel cell device and to evaluate it with respect to at least one previously determined value of the device variable of the fuel cell device.
Abstract:
The invention relates to a method for detecting impurities in a gas tank having a predefined tank nominal volume, which method includes at least one of the following steps: (a) determining a theoretical pressure drop in the gas tank from a quantity of gas which is actually extracted, and comparing said theoretical pressure drop with a measured pressure drop in the gas tank, wherein a higher measured pressure drop indicates the presence of impurities; and (b) determining a gas volume which is theoretically present in the gas tank from the measured pressure and measured temperature in the gas tank, and comparing the gas volume which is theoretically present in the gas tank with the tank nominal volume in order to determine a volume taken up by impurities which are present.
Abstract:
A fuel cell system has at least one fuel cell unit for generating electrical energy, a unit for storing or dispensing electrical energy, an electrical consumer for consuming electrical energy, a diagnostic unit for ascertaining a functional capability of the at least one fuel cell unit during a diagnosis phase, and a control unit for determining an electrical power generated at least during the diagnosis phase by the at least one fuel cell unit.
