[0024] Please refer to Figure 1 This embodiment provides a hydrogen production and refueling integrated skid-mounted device 100, including a container skid 110. The container skid 110 has a first functional area 120 and a second functional area 130 formed by a partition plate. The first functional area 120 is provided with a control module 121 and a high-voltage module 122. The second functional area 130 is provided with a hydrogen production module 131, a compression module 132 and a refueling module 133 connected in sequence by process pipelines. The high-voltage module 122 is electrically connected to the hydrogen production module 131 and the compression module 132 respectively for power supply. The control module 121 is communicatively connected to the high-voltage module 122, the hydrogen production module 131, the compression module 132 and the refueling module 133 respectively.

[0025] Specifically, such as Figure 1 As shown, the integrated hydrogen production and refueling skid unit 100 includes a container skid 110, which preferably has a length of 40 feet. Its interior is divided into a first functional area 120 and a second functional area 130 by a vertically arranged partition. As a preferred layout, the first functional area 120 and the second functional area 130 are arranged side-by-side along the length of the container skid 110. This layout facilitates pipeline arrangement, improves space utilization, and makes the overall structure of the integrated hydrogen production and refueling skid unit 100 more compact.

[0026] like Figure 1As shown, the first functional area 120 is equipped with a control module 121 and a high-voltage electrical module 122. Preferably, the control module 121 adopts a highly reliable distributed control system architecture, which mainly includes three cooperating subsystems: an equipment automatic control system, a safety monitoring system, and a hydrogen refueling machine control system. The equipment automatic control system is responsible for precise process control of process units such as the hydrogen production module 131 and the compression module 132, including start-up, shutdown, adjustment, and sequential control. The safety monitoring system is independent of the equipment automatic control system and is specifically responsible for real-time monitoring of key safety parameters such as pressure, temperature, and hydrogen concentration within the integrated hydrogen production and refueling skid-mounted equipment 100. When the integrated hydrogen production and refueling skid-mounted equipment 100 is installed on a vehicle, it can perform safety functions such as emergency shutdown when interlock values ​​are reached, further improving the reliability and safety of use. The hydrogen refueling machine control system is responsible for managing the refueling process, including pre-cooling, pressure matching, and flow control. Through the settings of the control module 121, operators can clearly understand the entire hydrogen refueling operation status and perform unified parameter settings and scheduling, ensuring the safe, reliable and stable operation of the integrated hydrogen production and refueling skid equipment 100.

[0027] The control module 121 includes a control cabinet, wherein the control cabinet has at least two sets of CPU modules, power modules and communication interfaces to form a redundant configuration. This ensures that in extreme cases, the control module 121 will not lose control or be interrupted due to a single hardware failure, thus ensuring that the equipment always operates uninterruptedly under effective control and greatly improving the availability and safety of the equipment.

[0028] The high-voltage module 122 includes a main power switch, transformer, frequency converter, distribution cabinet, etc., and is responsible for converting and distributing the externally input power.

[0029] The second functional area 130 is equipped with a hydrogen production module 131, a compression module 132, and a refueling module 133, which are connected in sequence through process pipelines.

[0030] The hydrogen production module 131 is the source of hydrogen production. Its inlet is connected to an external deionized water preparation unit via a pipeline. The deionized water preparation unit is used to purify the raw water into high-purity deionized water to ensure the safety and efficiency of the electrolytic hydrogen production process. Optionally, the hydrogen production module 131 is detachably connected to the container skid 110, allowing for the replacement of different hydrogen production modules 131 based on actual needs, thus improving the flexibility of the hydrogen production process.

[0031] The compression module 132 includes a compressor that can receive hydrogen from the hydrogen production module 131 through a pipeline and compress it to a high pressure.

[0032] The refueling module 133 includes a hydrogen refueling gun, which can receive hydrogen under high pressure through a pipeline and safely and accurately refuel it into the hydrogen storage cylinder of a fuel cell vehicle or other hydrogen-using device.

[0033] It should be noted that, firstly, in one possible implementation of this application, in order to produce hydrogen of higher purity, such as... Figure 2 As shown, a separation module 134 is also provided in the second functional area 130. The separation module 134 is connected between the hydrogen production module 131 and the compression module 132 through a process pipeline. The separation module 134 is used to separate the gas generated by the hydrogen production module 131 to obtain hydrogen and to transfer the hydrogen to the compression module 132. The separation module 134 is connected to the high-voltage module 122 and the control module 121 respectively.

[0034] The hydrogen production module 131 produces a mixture of high-temperature hydrogen and oxygen in a wet gas. The separation module 134 can use principles such as gravity sedimentation, centrifugal separation, or cyclone separation to separate the liquid water from the gas in the mixture, thereby obtaining crude hydrogen with a low water content, and then transmitting it to the subsequent compression module 132 to improve the efficiency and purity of hydrogen production.

[0035] The separation module 134 is connected to the high-voltage module 122 and the control module 121 respectively. The high-voltage module 122 can provide power to the separation module 134, while the control module 121 is used to control the start and stop of the separation module 134.

[0036] The separation module 134 can effectively remove liquid water entrained in hydrogen, preventing liquid water from entering the subsequent compression module 132, reducing the possibility of damage to the integrated hydrogen production and refueling skid equipment 100, and ensuring the stability and safety of the process.

[0037] Second, in one possible implementation of this application, such as Figure 2 As shown, a purification module 135 is also provided in the second functional area 130. The purification module 135 is connected between the separation module 134 and the compression module 132 through a process pipeline. The purification module 135 is used to dry and purify the hydrogen gas from the separation module 134 and transfer the purified hydrogen gas to the compression module 132. The purification module 135 is connected to the high-voltage module 122 and the control module 121 respectively.

[0038] Specifically, the hydrogen gas separated by separation module 134 may still contain impurities such as water vapor and trace amounts of oxygen. Optionally, purification module 135 includes a drying unit and a deoxygenation unit for deep drying and purification of the hydrogen gas. The drying unit removes water vapor, and the deoxygenation unit uses a catalyst to react trace amounts of oxygen in the hydrogen gas with the hydrogen to produce water, which is then removed through a subsequent drying process, ultimately yielding high-purity dried hydrogen gas, which is then transferred to compression module 132.

[0039] The purification module 135 is connected to the high-voltage module 122 and the control module 121. The high-voltage module 122 provides power to the purification module 135, while the control module 121 is used to control the start and stop of the purification module 135.

[0040] The purification module 135 can produce hydrogen of extremely high purity, meeting the stringent requirements of fuel cells for hydrogen quality, preventing impurities from causing irreversible poisoning damage to the fuel cell stack, and extending the service life of the fuel cell.

[0041] The integrated hydrogen production and refueling skid-mounted unit 100 improves space utilization and unit integration by dividing the container skid 110 into functional areas and integrating the existing discretely distributed modules into the corresponding functional areas. This reduces the footprint and thus lowers installation costs. The collaborative arrangement of multiple modules optimizes the process flow and improves equipment operating efficiency. The aforementioned integrated hydrogen production and refueling skid-mounted unit 100, through its highly integrated functional zoning configuration, significantly reduces footprint, lowers costs, and enhances operational synergy.

[0042] Optionally, such as Figure 3 As shown, the container skid 110 includes a main frame 111 and a cover 112. The main frame 111 has a accommodating cavity with a top opening, and the first functional area 120 and the second functional area 130 are both disposed in the accommodating cavity. The cover 112 covers the top opening of the accommodating cavity. A hydrogen storage cylinder module 140 is detachably disposed on the top of the cover 112. The hydrogen storage cylinder module 140 is connected to the refueling module 133 through a pipe.

[0043] Specifically, the container skid 110 includes a main frame 111 and a cover 112. The main frame 111 has a top-opening accommodating cavity, within which the aforementioned first functional area 120 and second functional area 130 are both located. The cover 112 covers and seals the top opening of the accommodating cavity. This arrangement improves the structural rigidity and stability of the integrated hydrogen production and refueling skid.

[0044] To further improve the integration of the equipment and the efficiency of hydrogen refueling, such as Figure 3 As shown, a hydrogen storage cylinder module 140 is detachably mounted on the top of the cover 112. This hydrogen storage cylinder module 140 typically consists of a set of high-pressure hydrogen storage cylinders and is connected to the refueling module 133 below via a high-pressure pipeline. Its function is to act as a buffer tank; during vehicle refueling, the hydrogen storage cylinder module 140 can be rapidly vented to shorten refueling time and improve refueling efficiency; when no vehicle is refueling, the refueling module 133 can charge the hydrogen storage cylinder module 140 with gas for energy storage.

[0045] By installing the hydrogen storage cylinder module 140, the hydrogen storage capacity and refueling efficiency of the integrated hydrogen production and refueling skid are improved without increasing the equipment's footprint.

[0046] To ensure safety, the cover 112 may optionally be made of explosion-proof steel plate. This material has high strength and high impact resistance, and can effectively suppress the propagation of blast shock waves and flames in the event of an accidental internal explosion, preventing the accident from escalating and protecting the safety of external personnel and equipment.

[0047] For example, the isolation plate is made of explosion-proof steel plate. Similarly, the explosion-proof steel plate provides a solid physical barrier, improving the safety of the integrated hydrogen production and refueling skid-mounted equipment.

[0048] In one possible implementation of this application, the control cabinet of the control module 121 is installed in the first functional area 120 via a wire rope shock absorber. One end of the wire rope shock absorber is connected to the top of the container skid 110, and the other end is connected to the top of the control cabinet.

[0049] Wire rope shock absorbers utilize the dry friction and bending hysteresis generated by the deformation of multi-strand stainless steel wire ropes to effectively absorb broadband vibration and impact energy. They not only isolate high-frequency vibrations transmitted from the skid to the control cabinet but also effectively buffer low-frequency impacts during transportation.

[0050] This design effectively isolates vibrations and shocks from the transportation and operating environment, preventing precision components such as PLCs, circuit boards, and terminals inside the control cabinet from loosening, fatigue, or damage due to continuous vibration. By improving the shock resistance of the control module 121, the equipment failure rate caused by vibration is significantly reduced, ensuring the long-term stability and reliability of the entire hydrogen production and refueling skid-mounted equipment and extending its lifespan.

[0051] In another aspect, this invention provides a vehicle comprising an integrated hydrogen production and refueling skid 100. The integrated hydrogen production and refueling skid 100 can be fixedly connected to the vehicle's chassis or other components via fasteners. When the vehicle is parked, the integrated hydrogen production and refueling skid 100 can be connected to mains power to produce hydrogen and compress and store it in a hydrogen storage tank module 140. The produced hydrogen can be used to supplement the vehicle's fuel cell range, thereby improving the vehicle's driving range.

[0052] The above description is merely an optional embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.

[0053] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.
