An absorption fluid reservoir having a fluid inlet for receiving gases during a charging event and a gas analysis unit for detecting unwanted impurities in the gases prior to being received in the reservoir and a control unit for eliminating the gases having the impurities.

Fluid reservoir having a gas sensor and a filter

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.

Gas absorption reservoir with optimized cooling

Hydrogen or methane gas pressure container having a minimum volume of 1 ma prescribed maximum filling pressure, has a filter through which oxygen, methane respectively, can flow during uptake. The filter has an adsorbent for adsorbing impurities selected from the group consisting of a higher hydrocarbon, ammonia, an odorous substance, hydrogen sulfide and a mixture of two or more of these substances. The pressure container and the filter comprise porous metal organic frameworks as adsorbent.

Pressurised gas container or storage means containing a gas pressurised container with filter means

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.

Fuel cell system with fuel cell unit having means for storing or dispensing electrical energy

A fuel cell device has a fuel cell unit including at least two fuel cell elements which are coupled with one another in a way selected from the group consisting of a series coupling, a parallel coupling, and both, for conversion of chemical energy into an electrical energy, and an electronic control unit for controlling individual fuel cell elements of the fuel cell unit.

Fuel cell device

A vehicle has a fuel system operative to chemically reform a fuel gas, a supply unit for supplying the fuel system with the fuel gas, and a gas reservoir provided with a storage volume for an intermediate storage of the fuel gas, the storage volume having a size that is changeable.

Vehicle with a supply unit

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.

Apparatus for converting energy that can be operated with fuel, in particular fuel cell assembly

The fuel cell system has a fuel cell unit and a catalytically active reactor unit () for at least partial chemical transformation of an operating medium stream (), especially a reformer, gas purifier stage and/or a combustor, in which the catalytically active reactor unit () has a variable catalytically active reactor volume () acted on by the operating medium stream. To provide the fuel cell system with a higher efficiency and good dynamic behavior the catalytically active reactor unit is provided with at least one control device () for controlling and/or for changing the variable catalytically active reactor volume () acted on by the operating medium stream (). In a preferred embodiment the control device includes a first valve () for the reactor unit arranged downstream of the maximum reactor volume and a second valve () connected with the reactor unit upstream of the first valve, so that, when the second valve is opened and the first valve is closed, the operating medium stream () passes through an effective reactor volume that is smaller than the maximum reactor volume.

Fuel cell system including a catalytically active reactor unit with flow control means

The fuel cell apparatus has a fuel cell (), a pressurized fuel tank () for supplying fuel at a supply pressure and a pressure-reducing unit () for reducing the supply pressure to an operating pressure of the fuel cell. In order to improve the overall efficiency of the unit in comparison to the art the pressure-reducing unit () is constructed as a cooling apparatus for cooling at least one cooling element, preferably a condenser ().
