The tempering device 100 serves, in particular, to adhere to the temperature limits required during operation of the fuel cell device 106.

By means of the temperature control device 100, the fuel cell device 106 for this purpose is preferably either heated or cooled.

The fuel cell device 106 is in particular incorporated in a circuit 122 of a heat transfer medium.

By means of the circuit 122, in particular, the heat transfer medium can be supplied by the fuel cell device 106 and further components of the temperature control device 100.

For driving the heat transfer medium in this case in particular a pump 124 is provided.

The temperature control device 100 preferably comprises one or more heat exchangers 126, which are in particular provided with one or more fans 128 in each case. Alternatively, it may be provided that the temperature control device 100, one or more heat exchangers 126 are each associated with one or more fans 128. A heat exchanger 126 is in particular an air-liquid heat exchanger in order to be able to deliver heat from the environment of the temperature control device 100 to the heat transfer medium or else from the heat transfer medium to the surroundings of the temperature control device 100.

The tempering device 100 further comprises a storage tank 130, through which the heat transfer medium is feasible.

Furthermore, the storage container 130 is suitable for receiving fuel.

For this purpose, the storage container 130 preferably comprises an inner structure 132, which subdivides an inner space 134 of the storage container 130 into a storage area 136 on the one hand and a bypass area 138 on the other hand.

The bypass area 138 is, in particular, the part of the interior 134 which can be flowed through by the heat transfer medium.

The storage area 136 is in particular an area to which fuel, in particular hydrogen, can be supplied in order to store the fuel in the storage tank 130 or to be able to provide fuel by means of the storage tank 130.

The storage area 136 is in particular filled with a storage material, for example a hydride storage material, in particular metal hydride or complex hydride.

For example, storage material is provided in pellet form.

For optimized heat transfer can be provided that the

Memory material comprises graphite. The storage container 130 preferably comprises a storage port 140, via which fuel can be supplied to the storage region 136. Furthermore, fuel can also be discharged from the storage area 136 through the storage port 140.

However, it can also be provided that two separate storage ports 140 are provided for supplying or discharging the fuel to and from the storage area 136.

The storage container 130 further comprises two temperature control ports 142, through which the Umströmbereich 138 in the interior 134 of the storage container 130 is accessible. About the Temperieranschlüsse 142 is in particular the

Heat transfer medium into the storage container 130 can be introduced and discharged from the same.

The tempering connections 142 are preferably arranged at opposite ends 144 of the storage container 130 in order to allow a simple flow through the storage container 130 with the heat transfer medium.

For the circuit 122, a surge tank 146 is also still provided. This allows in particular a compensation for temperature-induced volume fluctuations of the heat transfer medium.

One or more valve devices 148 are used for targeted control and / or regulation of the circuit 122.

In particular, a cooling valve 150 provided in the region of the heat exchanger 126 can be provided in this case in order to control the flow through the

Heat exchanger 126 with heat transfer medium targeted to influence, in particular to release or lock. A temperature control valve 152 arranged in the region of the storage container 130 preferably serves for selectively releasing or blocking the flow of the storage container 130.

Optionally, further such valve devices 148 may be provided.

One or more temperature sensors 154 are used for targeted control of the circuit 122.

By means of a control device 156, in particular the pump 124 and / or the valve devices 148 can be specifically controlled and / or regulated to carry out a desired temperature control process.

In Fig. 1, a reference symbol 158 represents an optional additional component which can be tempered as an alternative or in addition to the fuel cell device 106 by means of the temperature control device 100.

It is also possible to provide a plurality of such additional components 158.

As an additional component 158, for example, a battery device, in particular an accumulator device, or a power electronics can be provided.

As shown in FIG. 1 also shows, the temperature control device 100 is preferably modular. As a module 160, in particular those components are combined with each other, which can be combined with each other for different load requirements in multiple execution.

Alternatively or additionally, it can be provided that individual components of the temperature control device, in particular the storage container 130, depending on the season and thus removed to accommodate different Temperieranforderungen or added in multiple quantities. From the reservoir 108 on the one hand, the fuel cell device 106 and on the other hand, the storage tank 130 with fuel, in particular hydrogen, supply bar.

For this purpose, one or more pressure reducers 162 and / or supply valves 164 are preferably arranged in the fuel feed 114, in particular the fuel line 118.

As a result, it is preferably possible to ensure that the fuel cell device 106 is supplied with fuel at an optimum pressure level.

Furthermore, this can also be a targeted loading and unloading of

Storage container 130 can be enabled.

The temperature control device 100 shown in FIG. 1 functions as follows:

In the storage area 136 of the storage container 130, a storage material, in particular hydride storage material is arranged.

If hydrogen is now introduced from the reservoir 108 into the storage area 136 via the fuel feed 114, the result is preferably an exothermic reaction, as a result of which the internal structure 132 of the storage tank 130 heats up.

This resulting heat is transferred to the heat transfer medium flowing in the circulating region 138 and is then available in the circuit 122 for the temperature control of components of the vehicle 102.

In particular, the heated heat transfer medium can be fed via the circuit 122 to the fuel cell device 106 in order to bring it to a desired operating temperature for starting it up. The storage container 130 is preferably filled with hydrogen so far that a subsequent discharge of the storage container, in which hydrogen is released, can be used to operate the fuel cell device 106.

In particular, a pressure reducer is dispensable in this operation, whereby in particular an efficiency of the overall system can be optimized.

When unloading the storage container 130, that is, when removing hydrogen from the storage material in the storage area 136 results in an endothermic reaction, whereby the inner structure 132 is cooled.

The thereby also cooling heat transfer medium in Umströmbereich 138 can be used for example for cooling the fuel cell device 106. Alternatively, in the case of too hot heat transfer medium or in the case of too cold heat transfer medium of the heat exchanger 126 are flowed through to selectively and depending on the ambient temperature to give heat to the environment or from the same.

By using the storage container 130 as part of the temperature control device 100, a particularly energy-efficient operation of the vehicle 102 preferably results.

In particular, the storage container 130, regardless of the design of the reservoir 108 allow a simple and efficient temperature control.

In the Figs. 2 through 6, an optimized embodiment of the storage container 130 is shown. Here, it is provided that the storage container 130 comprises a cylindrical outer wall 166, for example, which in particular forms an outer casing 168 of the storage container 130.

The receiving tubes 170 are, in particular, substantially circular-cylindrical in shape.

Preferably, one or more connecting channels 172 are provided, by means of which the receiving tubes 170 are fluidically connected to one another.

As a result, in particular a distribution of the fuel to be stored in the storage container 130, in particular hydrogen, to the receiving tubes 170 can be ensured.

An inner space of the receiving tubes 170 together form the storage area 136.

The part of the inner space 134 lying outside the receiving tubes 170 preferably forms the bypass area 138.

As can be seen in particular from FIG. 3, the receiving tubes 170 and the outer wall 166 are connected to one another by means of a plurality of webs 174.

In this case, the webs 174 form in particular a heat-conducting structure 176 and / or a fluid-conducting structure 178.

By means of the webs 174, the receiving tubes 170 are preferably kept at a distance from the outer wall 166. This makes it possible, in particular, to thermally insulate the receiving tubes 170 from the outer wall 166 in that a circulating region 138 of the heat transfer medium forming thereby can be flowed through, thereby reliably dissipating heat arising in the receiving tube 170 and thus keeping it away from the outer wall 166.

The entire storage container 130 or at least the outer wall 166, the receiving tubes 170 and the webs 174 are preferably made of a metallic material, in particular an aluminum alloy, in an SD printing process.

For filling the receiving tubes 170 with storage material, the storage container 130 is preferably formed in two parts, wherein a part of the outer wall 166, the receiving tubes 170 and the webs 174 forms or includes. The further part is preferably an end cap 180, which can be placed on the first-mentioned part to complete the interior 134 of the storage container 130.

This end cap 180 is arranged in particular at one end 144 of the storage container 130 and, like the other end 144, comprises one of the temperature control connections 142.

The end cap 180 may in particular be welded or glued on.

The end cap 180 is preferably made fluid-tight.

The configuration of the storage container 130 described with reference to FIGS. 2 to 6 preferably results in a simple and cost-effective as well as lightweight, compact and energy-efficient design of the storage container 130. As in particular the Fig. 4 to 6, an internal structure of the storage container 130 is comparatively complex.

In particular, the connection channels 172 and the memory connection 140 are part of a distributor structure 182.

The entire distributor structure 182 is preferably formed integrally with the receiving tubes 170 and the webs 174 and the outer wall 166 connecting the receiving tubes 170.

The receiving tubes 170 are delimited at one end 144 by the distributor structure 182.

At the opposite end 144, the receiving tubes 170 are preferably closed by means of closure elements 184.

The closure elements 184 are in particular subsequently introduced into the receiving tubes 170 or fixed thereto, preferably after the receiving tubes 170 have been filled with storage material.
