Description

Hybrid fuel cell vehicle Technical Field

[0001] The present invention relates to a fuel cell vehicle, in particular to a composite fuel cell vehicle suitable for emergency power generation. Background Art

[0002] As electronic devices become increasingly sophisticated across various fields, the need for emergency power becomes increasingly crucial. Due to the negative environmental impact of greenhouse gas emissions, countries worldwide are committed to developing environmentally friendly alternative energy sources. Hydrogen is a rapidly emerging energy source. Compared to alternative energy sources like wind and solar power, hydrogen offers the advantage of being unconstrained by the natural environment, enabling stable energy conversion. It is a key fuel source for fuel cells today. In addition to fuel cell applications, hydrogen also has applications in the petroleum, steel, and food processing industries. As fuel cell technology advances, its applications are constantly evolving.

[0003] Currently, most emergency power generation vehicles using hydrogen fuel cells are general heavy-duty trucks (gasoline and diesel heavy-duty trucks) or fuel cell vehicles modified with hydrogen fuel cell power generation devices. They are pure emergency power generation vehicles that perform emergency power generation after reaching the destination, and their use is relatively limited.

[0004] Furthermore, the current lack of a robust hydrogen energy supply chain and a comprehensive infrastructure, such as hydrogen refueling stations, has dampened many consumers' initial enthusiasm for fuel cell applications. Hybrid fuel cell vehicles, however, can promote the use of hydrogen energy and address related infrastructure challenges.

The architecture of the composite fuel cell vehicle in some embodiments will be further described in detail below.

[0027] Please refer to Figure 1, which illustrates a side view of a hybrid fuel cell vehicle 10 according to some embodiments of the present invention. Hybrid fuel cell vehicle 10 includes a body 100, which includes a chassis 120 and a housing unit 110 above chassis 120. Hybrid fuel cell vehicle 10 can be a heavy truck, a van, or a box truck, and can simultaneously perform logistics, emergency power generation, and emergency hydrogen supply functions.

[0028] The housing unit 110 is provided with a hydrogen production module 112 and a storage tank 114. The storage tank 114 is used to store hydrogen production raw materials and provide hydrogen production raw materials to the hydrogen production module 112. The hydrogen production module 112 is used to provide hydrogen to the fuel cell module 124. The details of the fuel cell module 124 will be described in detail later.

[0029] In some embodiments, the housing unit 110, in addition to housing the hydrogen production module 112 and storage tank 114, can also be used to transport general cargo. In some embodiments, the housing unit 110 can be separate from the vehicle body 100, such as a container or cargo bed. In some embodiments, the housing unit 110 can be integrated with the vehicle body 100, such as a passenger compartment. Therefore, the size and shape of the housing unit 110 can be modified as needed and are not particularly limited by the present invention.

[0030] In some embodiments, hydrogen production module 112 may include, for example, a reactor, a purification device, etc. The hydrogen feedstock may be converted into hydrogen in the reactor of hydrogen production module 112 by methods such as steam reforming, partial oxidation reforming, and autothermal reforming. The hydrogen feedstock may be reformed in the reactor of hydrogen production module 112 at a suitable reaction temperature (e.g., between about 270° C. and about 450° C.) and under a suitable catalyst.

[0031] In some embodiments, after the methanol steam reforming system is started, the methanol water solution is transported to the reactor at a pressure of 10 to 12 bar by a methanol water pump, and the methanol water solution is subjected to a steam reforming reaction at a temperature between 270 and 450°C with the steam reforming catalyst. The methanol water solution is preheated by a heat exchanger and the generated high-temperature hydrogen. The methanol water fuel undergoes a methanol cracking reaction and a water gas shift reaction under the action of the steam reforming catalyst. The reaction formulas are: (1) methanol cracking reaction: CH3OH→CO+2H2, (2) water gas shift reaction: Actual steam reforming: CH3OH + H2O → xCO2 + yCO + zCH4 + mH2 + nH2O. The methanol-water reforming reaction produces a hydrogen-rich gas with a hydrogen content of only approximately 60-70%, still containing CO, CO2, CH4, and some water vapor. This hydrogen-rich gas enters the hydrogen purification unit. After purification by the purification module, the hydrogen passes through an adsorption device to completely remove carbon monoxide, water, and other gases, resulting in hydrogen with a purity exceeding 99.97%. The high-temperature hydrogen is supplied to the methanol-water preheating unit through a heat exchanger, which also cools the produced hydrogen. Furthermore, the hydrogen-rich gas that does not pass through the purification module is directed to a burner for combustion. The heat generated by this combustion is then used to supply the reactor with the heat required for the methanol steam reforming reaction, operating in a self-heating mode and minimizing energy consumption.

[0032] In some embodiments of the present invention, a hydrogen purification device comprises a purification module and an adsorption device. The purification module utilizes a flat-plate purification module, characterized by its material being fabricated using a stacked thin film process, rather than a conventional cylindrical porous ceramic surface coating process. The purification module purifies the hydrogen-rich gas produced by the reactor, removing carbon dioxide, carbon monoxide, methane, or unreacted methanol precursors generated by the steam reforming reaction, resulting in high-purity hydrogen. In some embodiments, the purity of the hydrogen purified by the purification module is greater than 99.95%. The purification module is a palladium alloy module formed by stacking palladium alloy thin films, which may include at least 15 wt%, at least 20 wt%, at least 25 wt%, at least 30 wt%, at least 35 wt%, at least 40 wt%, at least 45 wt%, at least 50 wt%, at most 60 wt%, at most 55 wt%, at most 53 wt%, at most 50 wt%, at most 45 wt%, at most 40 wt%, at most 35 wt%, at most 30 wt%, and / or at most 25 wt% copper. In a specific embodiment, the purification module is a palladium alloy module formed by stacking palladium alloy thin films comprising 60 wt% palladium and 40 wt% copper. Compared to conventional palladium membrane tube technology, the purification device of the present invention features a high-selectivity and high-permeability hydrogen filter membrane with excellent mechanical strength. Similarly, as a hydrogen purification device, for the same fuel cell power output, the flat-plate purification module has the advantage of being smaller in size. Furthermore, the purification module temperature is similar to the reactor temperature, so during the reformer reaction, heat can also be supplied to the purification module. Both heat sources are generated by directing the hydrogen-rich gas that fails to permeate the purification module into the burner for combustion, where it is combined with air as a combustion aid to maintain the required operating temperature. The unique high hydrogen permeability of the palladium metal in these membranes is utilized to purify the hydrogen-rich gas. Since the operating temperature must be between 330°C and 430°C, hydrogen can permeate these membranes, limiting the permeation of gases other than hydrogen in the hydrogen-rich gas. The hydrogen-rich gas is then introduced into the burner as combustion fuel and combined with air for combustion, generating heat that provides a high-temperature environment in the purification module through heat transfer. Therefore, the differential permeability of hydrogen and other gases through these membranes can be exploited to achieve hydrogen purification. In some embodiments, the material of at least one of the thin films is a noble metal or a noble metal alloy. In some embodiments, the material of at least one of the thin films can be palladium or a palladium alloy.Compared to pressure swing adsorption (PSA), commonly used in hydrogen production from fossil feedstocks, which suffers from large size and relatively limited space, some embodiments of the present invention utilize membrane modules for purification, which achieve exceptionally high selectivity for hydrogen. Heat is transferred to the purification module via the high-temperature, hydrogen-rich gas, maintaining the module temperature at 330-430°C. Driven by the pressure differential across the membrane, hydrogen purification is achieved, thereby enhancing the safety of the hydrogen supply device.

[0033] In some embodiments of the present invention, the adsorption device can remove water vapor from the hydrogen purified by the purification module. In some embodiments, the adsorption device can be any suitable device structure. For example, the adsorption device can be a dry adsorber. The adsorption device can include an adsorbent, and the water vapor in the purified hydrogen can be removed by the adsorbent. For example, the adsorbent can include porous composite fiber adsorption materials, activated carbon, and various types of molecular sieves, but is not limited thereto. In some embodiments, the purity of the hydrogen after passing through the adsorption device is above 99.97%, and the carbon monoxide content in the hydrogen is less than 1ppm. In addition, since the by-products in the steam reforming reaction contain some water vapor, this will affect the fuel cell's requirements for hydrogen quality, so the adsorption device is installed with the function of reducing the water content of the hydrogen to ensure that it meets the fuel cell hydrogen quality standards. The hydrogen produced by the hydrogen production module 112 can be provided to the fuel cell module 124 through an appropriate pipeline.

[0034] In some embodiments, the hybrid fuel cell vehicle 10 can also function as a mobile hydrogen refueling station, supplying the hydrogen generated by the hydrogen production module 112 to an external hydrogen receiving device 200 via appropriate pipelines. By continuously replenishing hydrogen production feedstock from an external source, the hybrid fuel cell vehicle 10 can continuously produce hydrogen. The external hydrogen receiving device 200 can be, for example, a fuel cell, a fuel cell vehicle, a hydrogen storage material, a metal hydrogen storage material, a hydrogen storage tank, or a hydrogen refueling station. Specifically, the fuel cell can serve as backup power in a renewable energy smart grid, providing electricity when wind and solar power generation systems are inoperative. It also stores hydrogen production feedstock for backup when backup power is not needed, thereby addressing the intermittent nature of renewable energy and meeting the need for peak-to-valley power shifting. Because renewable energy generation fluctuates with seasonal climate, the hybrid fuel cell vehicle 10 can adjust power requirements to meet local needs, reducing long-distance power transmission losses. Furthermore, the fuel cell vehicle can be a disaster relief vehicle, such as an ambulance or fire truck, a car, a motorcycle, or an unmanned aerial vehicle (UAV).

[0035] Compared to methods that pressurize and store hydrogen before transporting it to its destination, the present invention generates hydrogen from hydrogen production feedstock, eliminating the need for pressurized hydrogen storage and the need for decompression during hydrogen supply. This improves the safety of the hydrogen supply system and enables stable, long-term energy storage. Furthermore, the hybrid fuel cell vehicle 10, acting as a mobile hydrogen refueling station, can be moved to the location where hydrogen is needed and then begin the hydrogen production process, achieving real-time hydrogen production.

[0036] According to some embodiments, the hydrogen production raw material stored in the storage tank 114 may be methanol, ethanol, ethylene glycol, or an aqueous solution of the above hydrogen production raw materials. The aqueous solution includes a mixture of hydrogen production raw materials and deionized water in a certain proportion, and the molar ratio is between 0.8 and 1.6. According to some embodiments, the storage tank 114 may also provide the hydrogen production raw materials stored therein to an external hydrogen production raw material receiving device 300 through an appropriate pipeline. The external hydrogen production raw material receiving device 300 may be, for example, a raw material tank of a chemical plant, a hydrogen production station, etc. The volume of the storage tank 114 may be, for example, about 200L to about 3500L, such as about 225L to about 1000L, about 300L to about 2000L, or about 500L to about 3000L. The size of the storage tank 114 may be adjusted according to needs, and the present invention is not particularly limited to this.

[0037] Continuing with FIG1 , the hybrid fuel cell vehicle 10 further includes an onboard power system 122, a fuel cell module 124, and an emergency power supply device 126, all of which are disposed on the chassis 120. The fuel cell module 124 utilizes the hydrogen generated by the hydrogen production module 112 to generate electricity, and the generated electricity can be output to the onboard power system 122 and the emergency power supply device 126. For example, the fuel cell module 124 can be a proton exchange membrane (PEM) fuel cell, and the catalyst used therein is not particularly limited, and can be, for example, catalyst powders such as platinum / carbon, platinum / ruthenium / carbon, etc. The number of battery cells of the fuel cell module 124 can be adjusted according to usage requirements to change its output voltage. The electricity generated by the onboard power system 122 through the fuel cell module 124 can be used to provide kinetic energy to the hybrid fuel cell vehicle 10. Specifically, hydrogen, serving as fuel, undergoes an oxidation-reduction chemical reaction with oxygen in the atmosphere in the fuel cell module 124 carried by the hybrid fuel cell vehicle 10, generating electrical energy to drive the electric motor in the onboard power system 122. The electric motor drives the mechanical transmission structure in the onboard power system 122, and then drives the walking mechanical structure of the onboard power system 122, thereby driving the hybrid fuel cell vehicle 10 forward, backward, and turning.

[0038] In some embodiments, the emergency power supply device 126 can be used to output electricity to the outside. The emergency power supply device 126 includes a distribution box, and the distribution box includes a DC-DC converter (Converter) and / or a DC-AC inverter (Inverter), which can determine whether the output current is direct current or alternating current according to demand. In some embodiments, the current output by the emergency power supply device 126 is direct current, and the voltage output by the emergency power supply device 126 can be 48V~600V. In some embodiments, the current output by the emergency power supply device 126 is alternating current, and the voltage output by the emergency power supply device 126 can be 110V~480V. Since the hybrid fuel cell vehicle 10 can use the hydrogen production raw materials transported by itself to generate electricity, it can generate electricity for a long time in an emergency. For example, in some embodiments, the hybrid fuel cell vehicle 10 can be used as an emergency power generation vehicle to provide power to hospitals, fire departments, financial institutions and other facilities in an emergency, or to provide power to disaster relief vehicles such as ambulances and fire trucks, or to provide charging pile power to charge electric vehicles. By continuously replenishing hydrogen production raw materials from the outside, the emergency power generation time can be extended.

[0039] Because conventional hydrogen fuel cell emergency power generation vehicles require large, high-pressure hydrogen storage tanks, and if extended power supply time is required, several more large tanks are required. Consequently, most current emergency power generation vehicles using hydrogen fuel cells are converted from conventional heavy trucks or fuel cell vehicles with additional hydrogen fuel cell power generation equipment and large, high-pressure hydrogen storage tanks. These vehicles are purely emergency power generation vehicles, and their space and functionality are relatively limited. However, this technical solution utilizes the hydrogen production module's ability to directly supply low-pressure hydrogen immediately after production, effectively producing hydrogen in real time and directly supplying it to hydrogen receiving facilities, thereby reducing or replacing the space required to accommodate large, high-pressure hydrogen storage tanks. Furthermore, the emergency power supply device 126 of the hybrid fuel cell vehicle 10 is positioned within the chassis 120, eliminating or reducing the space occupied by the storage unit 110. This device is then connected to the fuel cell module 124, enhancing the operational flexibility of the hybrid fuel cell vehicle 10 while maintaining the capacity of the hydrogen production feedstock that the hybrid fuel cell vehicle 10 can carry.

[0040] In addition, in some embodiments, the power source of the hybrid fuel cell vehicle 10 may also include a rechargeable battery (not shown). The rechargeable battery can be configured on the chassis 120 as an auxiliary power supply device for the on-board power system 122. For example, the rechargeable battery may include a lead-acid battery, a nickel-metal hydride battery, a lithium battery, or a sodium-sulfur battery, which can be used to store the extra power generated by the fuel cell module 124, and at the same time serve as a brake recharge system, and can also provide power for starting the hybrid fuel cell vehicle 10. In addition, when the vehicle is traveling at a low speed, only the rechargeable battery provides energy; when the vehicle is traveling at a higher speed, the fuel cell module 124 will provide additional power to the engine and charge the rechargeable battery at the same time.

[0041] According to some embodiments, the hydrogen production module 112 is located at the front of the housing unit 110, near the front of the hybrid fuel cell vehicle 10, and the storage tank 114 is located at the rear of the housing unit 110. According to some embodiments, the onboard power system 122 is located at the front of the chassis 120, near the front of the hybrid fuel cell vehicle 10, the emergency power supply device 126 is located at the rear of the chassis 120, away from the front of the hybrid fuel cell vehicle 10, and the fuel cell module 124 is located between the emergency power supply device 126 and the onboard power system 122. This spatial arrangement improves the convenience of external power and / or hydrogen supply. It also improves space utilization. For example, the size of the storage tank 114 can be adjusted during loading and unloading, allocating space according to needs. For example, this spatial configuration of the chassis 120 can reduce the length of electrical wiring and increase the efficiency of chassis 120 space utilization.

[0042] According to some embodiments of the present invention, the storage tank 114 can store, for example, 150 L of hydrogen production raw materials, and the hydrogen production efficiency of the hydrogen production module 112 can reach about 60% to about 72%, and the hydrogen production capacity is, for example, about 4.5 Nm 3 / h to about 120Nm 3 The fuel cell module 124 can provide about 5 kW to about 120 kW of power to the hybrid fuel cell vehicle 10 , and output a voltage of, for example, about 48 V to about 600 V DC, or provide about 5 kW to about 120 kW of power externally.

[0043] Although not shown in the accompanying drawings, in some embodiments of the present invention, the hydrogen production module 112 may include a preheater. During the hydrogen production process, before the hydrogen production raw material undergoes a recombination reaction, the hydrogen production raw material may be preheated by a preheater so that the recombination reaction can proceed at a faster rate, or the recombination reaction can proceed smoothly at a lower ambient temperature. In addition, in some embodiments, the hydrogen production module 112 may also include a heat integration and energy recovery system. In some embodiments, the heat integration and energy recovery system may include an off-gas burner, which heats and burns the waste gas generated during the hydrogen production process, and recovers and utilizes the heat energy of the waste gas. In some embodiments, the recovered heat energy can be provided to the preheater or reactor in the hydrogen production module 112. In some embodiments, the hybrid fuel cell vehicle 10 may also include a remote management system to control the hydrogen production and supply of the hybrid fuel cell vehicle 10.

[0044] In summary, the hybrid fuel cell vehicle 10 of this embodiment can normally be used as a logistics vehicle for transporting hydrogen production raw materials. The hydrogen production module 112 converts the hydrogen production raw materials into hydrogen, allowing the hybrid fuel cell vehicle 10 to use the hydrogen production raw materials as a fuel source for the fuel cell module 124. The electricity generated by the fuel cell module 124 is then supplied to the onboard power system 122, eliminating the need for additional gasoline, diesel, or other fossil fuels. Furthermore, because the hydrogen produced by the hydrogen production module 112 can be used immediately, the hybrid fuel cell vehicle 10 can be used as a mobile hydrogen refueling station. Furthermore, by configuring the emergency power supply device 126 on the chassis 120, the space within the housing unit 110 of the hybrid fuel cell vehicle 10 can be reduced or eliminated. This allows the fuel cell module 124 to not only provide the power required for vehicle movement but also output power, allowing the hybrid fuel cell vehicle 10 to function as an emergency power generator. Furthermore, the hybrid fuel cell vehicle 10 can also transport general cargo in addition to hydrogen production raw materials. From the above, it can be seen that the hybrid fuel cell vehicle of this case has flexibility in use and can be used in different scenarios, reducing the cost of purchasing different devices.

[0045] The above summarizes the features of several embodiments of the present invention, so that those skilled in the art can more easily understand the technical solution. Anyone of ordinary skill in the art should understand that this specification can easily serve as a basis for changing or designing other structures or processes to achieve the same purpose and / or obtain the same advantages as the embodiments of the present invention. Anyone of ordinary skill in the art can understand that structures or processes equivalent to the above do not depart from the spirit and scope of protection of this application, and can be changed, replaced and modified without departing from the spirit and scope of protection of this application.

[0046] In this specification, the present invention has been described with reference to specific embodiments thereof. However, it will be apparent that various modifications and variations may be made without departing from the spirit and scope of the present invention. Accordingly, the specification and drawings are to be regarded as illustrative rather than restrictive.
