[0028] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0031] Example:

[0032] like Figure 1-Figure 5 As shown, the extended-range fuel cell RV provided in this embodiment includes a vehicle body 1, a hydrogen fuel cell 2 and a hydrogen storage assembly 3; the hydrogen fuel cell 2 and the hydrogen storage assembly 3 are both installed at the rear of the vehicle body 1, and the hydrogen storage assembly 3 is arranged on one side of the hydrogen fuel cell 2; the hydrogen fuel cell 2 and the hydrogen storage assembly 3 are connected by a hydrogen supply pipeline, the hydrogen storage assembly 3 is used to supply hydrogen to the hydrogen fuel cell 2, and the hydrogen fuel cell 2 is used to supply electrical energy generated by the electrochemical reaction of hydrogen and oxygen to electrical equipment on the vehicle body 1.

[0033] The extended-range fuel cell RV provided in this embodiment can use the hydrogen storage component 3 to continuously supply hydrogen to the hydrogen fuel cell 2, and the hydrogen fuel cell 2 can perform an electrochemical reaction on hydrogen and oxygen in the air, and then generate water, electrical energy and thermal energy. Among them, the electrical energy can be supplied to the electrical equipment on the vehicle body 1, such as the engine and household appliances equipped with the extended-range fuel cell RV. Therefore, the extended-range fuel cell RV uses the energy generated by the electrochemical reaction of hydrogen and oxygen as the whole vehicle power of the extended-range fuel cell RV and the life energy required by the extended-range fuel cell RV. Since the product obtained after the electrochemical reaction of hydrogen and oxygen is usually water, compared with the energy generation method of burning gasoline, the extended-range fuel cell RV provided in this embodiment can effectively reduce the pollution of its emissions to the environment.

[0034] Compared with the prior art, the extended-range fuel cell RV provided in this embodiment generates electrical energy through the electrochemical reaction of hydrogen and oxygen by the hydrogen fuel cell 2 at the rear, and then supplies the electrical energy to the engine, household appliances and other electrical equipment on the vehicle body 1 as the power of the entire vehicle. There is no need to burn gasoline. Since the emissions generated by the electrochemical reaction of hydrogen and oxygen are water, the extended-range fuel cell RV can effectively reduce pollution to the environment.

[0035] Among them, Figure 4 and Figure 5As shown, the hydrogen fuel cell 2 may also be provided with a discharge port, which is connected to a tail pipe 4 , and the product of the electrochemical reaction between hydrogen and oxygen in the air may be discharged through the tail pipe 4 .

[0036] It should be noted that even if hydrogen and oxygen in the air do not fully undergo an electrochemical reaction and the reaction products are mixed with hydrogen or air, compared to the products after gasoline combustion, hydrogen and air are both clean gases. Therefore, when water is discharged from the tail pipe 4 along with hydrogen or air, the degree of pollution to the environment is still relatively low.

[0037] In addition, it should be noted that the extended-range fuel cell RV provided in this embodiment can not only make full use of the limited space on the extended-range fuel cell RV, but also effectively improve the center of gravity of the extended-range fuel cell RV by installing both the hydrogen fuel cell 2 and the hydrogen storage assembly 3 at the rear of the vehicle body 1. Moreover, by arranging the hydrogen storage assembly 3 on one side of the hydrogen fuel cell 2, the distance between the hydrogen fuel cell 2 and the hydrogen storage assembly 3 can be effectively shortened, thereby effectively shortening the hydrogen supply pipeline and improving the working efficiency of the hydrogen fuel cell 2.

[0038] In order to further improve the working efficiency of the hydrogen fuel cell 2, an air compressor may also be provided in the hydrogen fuel cell 2, and the air compressor is used to drive external air into the reactor of the hydrogen fuel cell 2 so that oxygen in the air can smoothly undergo an electrochemical reaction with hydrogen.

[0039] like Figure 1 As shown, the extended-range fuel cell RV provided in this embodiment also includes a cooling assembly; the cooling assembly includes a cooling part and a heat dissipation part that are interconnected, the cooling part is attached to one side of the hydrogen fuel cell 2, and the cooling part is used to pass a cooling medium to exchange heat and cool the hydrogen fuel cell 2; the heat dissipation part is arranged on the top of the vehicle body 1, and the heat dissipation part is used to collect the medium that has been heated after heat exchange.

[0040] Since hydrogen and oxygen in the air will release heat energy to the outside during the electrochemical reaction in the reactor inside the hydrogen fuel cell 2, in order to ensure the service life and safety of the hydrogen fuel cell 2, it is also necessary to dissipate the above heat. Based on this, the extended-range fuel cell RV in this embodiment preferably also includes a cooling assembly and the cooling part in the cooling assembly is attached to one side of the hydrogen fuel cell 2.

[0041] The cooling component may be a heat exchanger or a refrigerator. Furthermore, the cooling portion of the cooling component is used to contain a cooling medium to facilitate heat conduction and heat exchange with the hydrogen fuel cell 2, thereby achieving the purpose of cooling the hydrogen fuel cell 2.

[0042] Among them, the heat dissipation part and the cooling part of the cooling component can be connected by a pipeline to form a connecting pipeline. When the cooling medium at the cooling part performs heat exchange and cooling on the hydrogen fuel cell 2, the medium will heat up. At this time, the heated medium can be made to flow to the heat dissipation part of the cooling component, thereby facilitating centralized cooling or recycling of the heated medium.

[0043] Further, such as Figure 2 and Figure 2 As shown, the extended-range fuel cell RV provided in this embodiment also includes a heat dissipation component 5, which is arranged on the top of the vehicle body 1 and on one side of the heat dissipation part. The heat dissipation component 5 is used to cool the medium in the heat dissipation part.

[0044] The heat dissipation component 5 is arranged on one side of the heat dissipation part to cool down the medium heated up after heat exchange at the heat dissipation part, so that the medium is cooled down again to become a cooling medium for recycling. Specifically, a circulation pipeline is connected between the heat dissipation part and the cooling part of the cooling component, and the circulation pipeline is used to allow the medium cooled down at the heat dissipation part to return to the cooling part for reuse.

[0045] Providing the heat dissipation component 5 on the top of the vehicle body 1 can not only effectively prevent the heat dissipation component 5 from occupying the space inside or on the chassis of the extended-range fuel cell RV, thereby improving the internal space utilization of the extended-range fuel cell RV, but also enable the heat dissipation component 5 and the heat dissipation part of the cooling component to be in an open space, thereby facilitating rapid cooling of the medium at the heat dissipation part.

[0046] The heat dissipation component 5 may be a refrigerator or other device. To simplify the structure of the heat dissipation component 5, the heat dissipation component 5 is preferably a heat dissipation fan in this embodiment.

[0047] like Figure 5 As shown, the cooling assembly further includes a deionizer 6 , which is in communication with the cooling portion and is disposed on one side of the hydrogen fuel cell 2 .

[0048] The deionizer 6 is used to remove conductive ions in the medium at the cooling part of the cooling assembly, thereby improving the safety of the hydrogen fuel cell 2 .

[0049] Furthermore, a through opening may be provided on the side wall of the extended-range fuel cell RV, and the deionizer 6 is provided on one side of the through opening, so that consumables on the deionizer 6 can be directly replaced through the through opening outside the extended-range fuel cell RV.

[0050] like Figure 2 As shown, the hydrogen storage assembly 3 is provided with a hydrogen filling port 30 , which is located on one side of the inner wall of the vehicle body 1 , and a working window 10 is provided on the side wall of the vehicle body 1 close to the hydrogen filling port 30 .

[0051] When the hydrogen in the hydrogen storage assembly 3 is insufficient, external hydrogen can be injected into the hydrogen storage assembly 3 through the hydrogen filling port 30 to supplement the hydrogen.

[0052] Furthermore, in order to facilitate the connection between the hydrogen storage component 3 and an external hydrogen source, a hydrogenation pipeline can be connected to the hydrogen storage component 3, one end of the hydrogenation pipeline is connected to the cavity for storing hydrogen inside the hydrogen storage component 3, and the other end of the pipe opening is a hydrogenation port 30.

[0053] The hydrogen refueling pipeline can be fixed to one side of the hydrogen storage assembly 3 by fasteners such as snaps. When the hydrogen storage assembly 3 needs to be supplemented with hydrogen, the hydrogen refueling pipeline can be separated from the fasteners, thereby facilitating the hydrogen refueling port 30 of the hydrogen refueling pipeline to pass through the working window 10 on the side wall of the vehicle body 1 and connect with an external hydrogen source.

[0054] In order to facilitate the control of the hydrogenation process, a valve may be provided on the hydrogenation pipeline, and the valve is used to control the on-off of the hydrogenation pipeline.

[0055] In addition, the hydrogenation port 30 may be connected to an external hydrogen source via a pressure regulating device, and the pressure regulating device is used to regulate the gas pressure during the hydrogenation process.

[0056] In this embodiment, the hydrogen storage assembly 3 can be arranged between the hydrogen fuel cell 2 and the rear side wall of the vehicle body 1. At this time, the hydrogen storage assembly 3 is closer to the rear of the vehicle body 1 than the hydrogen fuel cell 2. Correspondingly, the hydrogen refueling port 30 is located near the rear of the vehicle body 1, and the working window 10 on the side wall of the vehicle body 1 is arranged on the side wall of the vehicle body 1 near the rear of the vehicle body 1.

[0057] The working window 10 on the side wall of the vehicle body 1 is arranged at a position of the side wall of the vehicle body 1 close to the rear of the vehicle body 1 , which can provide a relatively open space for the hydrogenation operation, thereby facilitating the hydrogenation operation.

[0058] like Figure 3 and Figure 5 As shown, one side of the hydrogen fuel cell 2 is connected to an oxygen inlet channel, and an air filter 7 is provided on the oxygen inlet channel.

[0059] The air filter 7 is used to filter the external air so that the air entering the reactor of the hydrogen fuel cell 2 through the oxygen inlet channel is clean gas.

[0060] Further, such as Figure 1 As shown, the air filter 7 is installed inside the vehicle body 1, and the air filter 7 is opposite to the working window 10 on the side wall of the vehicle body 1. At this time, the working window 10 is not only convenient for hydrogenation operation, but also convenient for a large amount of external air to pass through the air filter 7 and enter the oxygen inlet channel.

[0061] like Figure 5As shown, the extended-range fuel cell RV provided in this embodiment also includes a voltage converter 8, which is arranged on the top of the hydrogen fuel cell 2, and the voltage converter 8 is connected between the hydrogen fuel cell 2 and the electrical equipment on the vehicle body 1.

[0062] Furthermore, the extended-range fuel cell RV provided in this embodiment also includes a distributor; the electrical equipment on the vehicle body 1 includes an engine controller, and the distributor is connected between the converter and the engine controller.

[0063] The electric energy generated by the hydrogen fuel cell 2 is distributed by the voltage converter 8 to various electrical equipment on the extended-range fuel cell RV. The high-voltage current is distributed by the voltage converter 8 to the distributor, and then distributed to the engine controller of the extended-range fuel cell RV via the distributor. The engine controller controls the engine start and provides power for the engine of the extended-range fuel cell RV.

[0064] In this embodiment, the voltage converter 8 may be a DCDC converter (DC-to-DC converter, also known as a DC-DC converter), and the distributor may be a PDU (Power Distribution Unit) distribution box.

[0065] In addition, the extended-range fuel cell RV provided in this embodiment may also include a fuel cell controller and a host computer. The host computer is arranged in the cab of the vehicle body 1, and the host computer and the hydrogen fuel cell 2 are both connected to the fuel cell controller.

[0066] The host computer can be a computer with a touch screen. During use, the user can control the fuel cell controller through the host computer to perform various operations, such as starting and stopping the hydrogen fuel cell 2 through the cooperation between the host computer and the fuel cell controller.

[0067] Furthermore, the upper computer of the extended-range fuel cell RV can also be equipped with a one-touch start switch and a stop switch for the hydrogen fuel cell 2 .

[0068] It should be noted that in order to improve the installation stability of the hydrogen fuel cell 2 in the extended-range fuel cell RV, Figure 5 As shown, a bracket 9 may also be provided inside the extended-range fuel cell RV, and the hydrogen fuel cell 2 is installed on the bracket 9 .

[0069] In addition, the extended-range fuel cell RV provided in this embodiment may also include a range extender, which is installed inside the vehicle body 1 and connected to the hydrogen fuel cell 2. The range extender is used to provide additional electrical energy when the hydrogen fuel cell 2 has insufficient electrical energy to increase the mileage of the extended-range fuel cell RV.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
