Description

Technical Field

[0001] This invention belongs to the field of fuel cell technology, and specifically relates to a modular, high-efficiency hydrogen production fuel processor and its application. Background Technology

[0002] A fuel cell is a device that directly converts the chemical energy stored in a compound fuel into electrical energy through a chemical reaction. The fuel processor is the hydrogen supply unit for the fuel cell and mainly includes an endothermic reforming chamber, a combustion chamber that provides the heat source, and related accessories. If the arrangement is not reasonable, internal gas "short-circuiting" (not participating in the reaction), low fuel thermal efficiency, long start-up time, poor hydrogen production efficiency, and a large, non-compact size can occur, significantly impacting the overall power generation efficiency, specific power, and lifespan of the fuel cell. Furthermore, due to its complex structure, the manufacturing cost is high.

[0003] This invention proposes a fuel processor with a highly compact structure that can be manufactured by aluminum extrusion, resulting in low manufacturing cost and high thermal efficiency. It also solves the problem of gas "short circuit" caused by particulate catalyst deposition in the reforming chamber, facilitating equipment scale-up. It is particularly suitable for methanol steam reforming to produce hydrogen in high-power high-temperature proton exchange membrane fuel cells (HT-PEMFC), effectively improving the efficiency of the fuel processor and fuel cell system.

[0036] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] like Figures 1(A)-1(B) As shown, an embodiment of the present invention provides a modular high-efficiency hydrogen production fuel processor, including a combustion chamber module 20 and multiple reforming chamber modules 1 connected in series or parallel; wherein, the reforming chamber module 1 includes a combustion exhaust gas chamber 12 and a reforming chamber 14 disposed within the combustion exhaust gas chamber 12 and having a wave-shaped structure, the combustion exhaust gas chamber 12 being connected to the combustion chamber module 20; the reforming chamber 14 is filled with particulate reforming catalyst, and an endothermic reaction of methanol-water vapor reforming occurs within the reforming chamber 14 for the reforming hydrogen production reaction; the combustion exhaust gas generated by the catalytic combustion reaction in the combustion chamber module 20 enters the combustion exhaust gas chamber 12, providing heat for the endothermic reforming reaction in the reforming chamber 14.

[0038] In the embodiments of the present invention, the reforming chamber module 1 has a cuboid structure; multiple reforming chamber modules 1 are arranged in parallel, and the combustion exhaust gas chambers 12 of two adjacent reforming chamber modules 1 are laterally connected; the beginning and end ends of the reforming chambers 14 of two adjacent reforming chamber modules 1 are connected in series through the reforming manifold, and the front and rear ends of the entire reforming chamber are respectively provided with a methanol water vapor inlet F for reforming reaction and a reforming exhaust gas outlet E.

[0039] like Figures 9-10As shown, in this embodiment, there are four reforming chamber modules 1. A first reforming manifold 2, connected to a reforming chamber 14, is located at the front end of the first reforming chamber module 1. A methanol steam inlet F for the reforming reaction is located at the front end of the first reforming manifold 2. The reforming chambers 14 in the first to fourth reforming chamber modules 1 are connected in series via a second reforming manifold 3, a third reforming manifold 4, and a fourth reforming manifold 5. A fifth reforming manifold 6, connected to a reforming chamber 14, is located at the front end of the fourth reforming chamber module 1. A reforming tail gas outlet E is located at the front end of the fifth reforming manifold 6. In other words, the first reforming manifold 2, the third reforming manifold 4, and the fifth reforming manifold 6 are located at the front end of the four reforming chamber modules 1, while the second reforming manifold 3 and the fourth reforming manifold 5 are located at the rear end of the four reforming chamber modules 1, forming a meandering flow channel with the reforming chambers 14 connected in series.

[0040] Specifically, such as Figure 5 As shown, the first reforming collector 2 and the fifth reforming collector 6 have the same structure, including a shell and a methanol steam inlet F or a reforming tail gas outlet E located at the front end of the shell. Figure 6 As shown, the double-rectifying flow cavity 3, the third-rectifying flow cavity 4, and the fourth-rectifying flow cavity 5 have the same structure, all including a square shell.

[0041] like Figures 2(A)-2(B) As shown, in an embodiment of the present invention, the combustion chamber module 20 includes a combustion chamber 7 and a combustion manifold I8 connected to the combustion chamber 7. The combustion chamber 7 is provided with a combustion catalyst 9. The front end of the combustion chamber 7 is provided with a combustion air inlet A, an anode exhaust gas inlet B and a starting fuel inlet C. The combustion manifold I8 is located on the rear side of the combustion chamber 7.

[0042] As shown in Figure 1(B), in an embodiment of the present invention, combustion collection chambers II 10 and III 11 are respectively provided on both sides of multiple reforming chamber modules 1. Combustion collection chamber II 10 is located between combustion chamber module 20 and reforming chamber module 1. Combustion exhaust gas in combustion collection chamber I 8 in combustion chamber module 20 enters combustion collection chamber II 10. Combustion collection chamber III 11 has a combustion exhaust gas outlet D at its front end.

[0043] like Figure 7 As shown, in an embodiment of the present invention, a combustion exhaust gas inlet 22 is provided at the rear end of the combustion collecting chamber II 10, and the combustion exhaust gas inlet 22 is connected to the end of the combustion collecting chamber I 8; furthermore, a partition I 21 located in front of the combustion exhaust gas inlet 22 is provided inside the combustion collecting chamber II 10, and the partition I 21 divides the combustion collecting chamber II 10 into two chambers. Figure 8 As shown, the combustion collecting chamber Ⅲ11 is provided with a baffle Ⅱ23 located behind the combustion exhaust gas outlet D, which also divides the combustion collecting chamber Ⅲ11 into two chambers.

[0044] In this embodiment, the combustion chamber 7 contains a combustion catalyst 9, and one or more can be arranged as needed. The combustion exhaust gas can also be connected in series or parallel through a simple baffle plate, and the equipment can be scaled up by arranging and combining it with the reforming chamber module in series or parallel.

[0045] like Figures 3(A)-3(B) As shown, in an embodiment of the present invention, two wave-shaped reforming chamber cover plates 13 are arranged parallel to each other inside the combustion exhaust gas chamber 12, forming a wave-shaped reforming chamber 14 between the two reforming chamber cover plates 13. Further, the crest of the upper reforming chamber cover plate 13 connects to the upper inner wall of the combustion exhaust gas chamber 12, and the trough of the lower reforming chamber cover plate 13 connects to the lower inner wall of the combustion exhaust gas chamber 12, forming multiple independent small chambers on the upper and lower sides of the reforming chamber 14. The small chambers in two adjacent reforming chamber modules 1 correspond one-to-one, thereby forming a combustion exhaust channel laterally, and communicating with the combustion collecting chamber II 10 and the combustion collecting chamber III 11 on both sides, as shown. Figure 9 As shown.

[0046] Specifically, the reforming chamber module 1 is manufactured using an aluminum extrusion process. It is surrounded by combustion exhaust gas chambers 12, with a reforming chamber 14 at its center. The combustion exhaust gas chambers 12 enclose the reforming chamber 14, increasing the thermal surface area and enhancing heat exchange capacity. The reforming chamber 14 is filled with granular reforming catalyst for the hydrogen production reaction. The reforming chamber 14 employs a corrugated flow channel design to prevent catalyst deposition and gas short circuits within the reforming chamber.

[0047] Furthermore, the outer wall of the reforming chamber 14 is provided with multiple serrated fins, so that more heat can be conducted to the heat-absorbing reforming chamber 14 in a more uniform manner.

[0048] Figure 4(A) is a schematic diagram of the flow path in the prior art reforming chamber. As shown in Figure 4(A), due to the sedimentation of the particulate catalyst during use, if the conventional straight chamber design is adopted, the reforming reaction gas will flow directly away from the voids 16 formed by sedimentation at the top, forming a "short circuit" and failing to fully contact the catalyst, greatly reducing the reforming efficiency. Figure 4(B) is a schematic diagram of the improved flow path in the reforming chamber of the present invention. As shown in Figure 4(B), the reforming chamber 14 adopts a wave-shaped flow channel design. After the catalyst settles, the voids 16 will accumulate at the crest of the flow channel, but the main flow channel is still filled with catalyst. The reaction gas will fully contact the catalyst through the wave-shaped flow channel and react fully, solving the problem of gas short circuits that easily occur in the reforming chamber.

[0049] In an embodiment of the present invention, the combustion exhaust chamber 12 encloses the reforming chamber 14. The wave-shaped flow channel design keeps the bed thickness in the reforming chamber 14 constant at 15-25 mm. Compared with the traditional flat direct flow channel, this increases the amount of reforming catalyst per unit volume, improves the processor's processing capacity, and helps improve the volumetric power ratio of the entire fuel cell system. As shown in Figure 4(A), the reforming catalyst filling volume of the traditional flat direct flow channel is 1 / 3 of the entire chamber, while in Figure 4(B), the reforming catalyst filling volume of the wave-shaped flow channel is 2 / 3 of the entire chamber. With the bed thickness unchanged, the catalyst filling volume can be increased by adjusting the wave angle. At the same time, compared with the traditional flat direct flow channel, the wave-shaped flow channel of the present invention shortens the heat transfer distance of the reforming chamber, increases the heat transfer specific surface area, and allows the catalyst per unit volume to receive more heat. The peripheral serrated fins allow more and more heat to be conducted to the heat-absorbing reforming chamber 14, which is conducive to the efficient reforming reaction and rapid heating during the start-up phase. The contact area between the reforming chamber 14 with the wavy flow channel and the combustion exhaust gas chamber 12 is more than 50% larger than that of the straight flow channel.

[0050] like Figures 9-10 As shown, in the embodiments of the present invention, the combustion exhaust gas flow channel is a three-pass series connection, and the reforming chamber flow channel is a four-pass series connection. The combustion exhaust gas and the reforming chamber 14 undergo cross-flow heat transfer, resulting in high thermal efficiency. At the same time, the reforming chamber module 1 can be arranged in series and parallel, and can be connected by welding, which can be easily stacked and combined, and the equipment can be easily scaled up. The arrangement of the combustion chamber can also be changed with the arrangement of the reforming chamber modules. It is especially suitable for the methanol steam reforming hydrogen production reaction in high-power high-temperature proton exchange membrane fuel cells (HT-PEMFC), effectively improving the efficiency of the fuel processor and fuel cell system.

[0051] During system startup, the methanol-water solution evaporates and enters the combustion chamber 7 through the startup fuel inlet C for catalytic combustion. Once the system meets the startup conditions, the startup fuel supply is shut off. The methanol-water solution is vaporized through external evaporation and enters the reforming chamber 14 through the reforming reaction methanol-water vapor inlet F. The hydrogen produced by the reaction is discharged through the reforming tail gas outlet E and used as the anode fuel for fuel cell stack power generation. The anode tail gas of the fuel cell stack returns to the combustion chamber 7 for catalytic combustion to maintain normal system operation.

[0052] Another embodiment of the present invention provides an application of the modular high-efficiency hydrogen fuel processor as described in any of the above embodiments, wherein the modular high-efficiency hydrogen fuel processor is used to provide the required reaction gas to a fuel cell unit.

[0053] Specifically, the hydrogen-rich reactive gas generated by the modular high-efficiency hydrogen fuel processor enters the fuel cell stack to participate in the reaction and generate electricity. The excess hydrogen-rich tail gas from the stack anode returns to the combustion chamber module 20 for catalytic combustion, providing heat for reforming.

[0054] During operation, in the system startup phase, the reforming reaction liquid evaporates and enters the combustion chamber 7 through the startup fuel inlet C for catalytic combustion and heat release. In the system operation phase, the fuel mixture of the anode and cathode exhaust gases of the fuel cell stack is used as burner fuel. The fuel enters the combustion chamber 7 through the anode exhaust gas inlet B for catalytic combustion and heat release, and the combustion exhaust gas is discharged from the combustion exhaust gas outlet D. The reforming reaction liquid enters the reforming chamber 14 of the reforming chamber module 1 through the reforming reaction methanol water vapor inlet F. Through the S-shaped flow channel inside the reforming chamber 14, it fully reacts to generate hydrogen-rich reaction gas. The hydrogen-rich reaction gas is discharged from the reforming exhaust gas outlet E and enters the fuel cell stack to participate in the reaction. The excess hydrogen-rich exhaust gas enters the combustion chamber 7 through the anode exhaust gas inlet B for catalytic combustion, providing heat for reforming.

[0055] Example

[0056] Taking the methanol steam reforming hydrogen production process of the present invention as an example, a methanol aqueous solution with a volume content of 60% is used as the reforming reaction liquid with a mass flow rate of 0.0087 kg / s. During the system start-up phase, the methanol aqueous solution with a mass flow rate of 0.006 kg / s is evaporated and catalytically combusted. An air flow rate of 1000-1200 L / min is introduced until the temperature of the combustion chamber is between 350-450°C. After the system meets the start-up conditions, the start-up fuel supply is shut off, and reforming fuel is introduced to start reforming. Hydrogen is generated and enters the anode reaction of the fuel cell stack to generate electricity. Afterwards, the residual tail gas from the anode of the fuel cell stack returns to the combustion chamber for catalytic combustion. The catalyst is platinum alumina with a platinum content of 0.5%. The reforming reaction liquid is vaporized externally and enters the reforming chamber 14 at about 160°C. The chamber temperature of the reforming chamber 14 is between 220°C and 300°C. It is filled with CuO / ZnO / Al2O3 catalyst, with CuO mass fraction of 50%, ZnO mass fraction of 10%, and Al2O3 mass fraction of 40%. The total mass of reforming catalyst is 20kg, which is about 5kg more than that of the conventional flat DC channel. The hydrogen content of the reforming tail gas is nearly 65% ​​(molar volume), the standard hydrogen flow rate is about 480L / min, and the carbon monoxide content is less than 1% (molar volume). As the anode fuel of the fuel cell stack, it can be used to meet the hydrogen requirements of the fuel cell stack operating at 30kW power generation. During the start-up phase, the heat from the combustion chamber and its exhaust is directly and rapidly transferred to the reforming chamber. The temperature rises from room temperature of 25°C to 300°C in 15-20 minutes, which is rapid and helps to shorten the start-up time.

[0057] This invention provides a modular, high-efficiency hydrogen production fuel processor with a highly compact structure. It can be manufactured by aluminum extrusion, resulting in low manufacturing costs and high thermal efficiency. It also solves the problem of gas short circuits that easily occur in the reforming chamber, facilitating equipment scale-up. It is particularly suitable for the methanol-water vapor reforming hydrogen production reaction in high-power high-temperature proton exchange membrane fuel cells (HT-PEMFC), effectively improving the efficiency of the fuel processor and fuel cell system.
