Abstract
Description
Technical Field
[0001] This application relates to the field of fuel cell technology, specifically to a fuel cell module. Furthermore, this application also relates to a fuel cell including such a fuel cell module. Background Technology
[0002] With the development of new energy vehicles, fuel cells, as the power source for new energy vehicles, have advantages in terms of environmental protection and energy density.
[0003] A fuel cell stack typically consists of multiple cells stacked on top of each other. Each cell is composed of a membrane electrode assembly, bipolar plates, and seals. These cells are pressed together on both sides by end plates along the stacking direction using insulating plates and current collectors to form the fuel cell stack.
[0004] Fuel cell stacks typically include supply channels for reactant gases, which supply these gases to the anode and cathode sides of the cell for electrochemical reactions. Additionally, to regulate the temperature of the fuel cell, corresponding coolant channels are provided within the stack. Coolant enters the cell's inlet through these channels, regulating the cell's temperature (e.g., cooling it), and then flows out from the cell's outlet into other coolant channels.
[0005] When battery cells are stacked and compressed, the seals not only provide a sealing function but also additionally provide support. However, since the seals are typically made of rubber or polymer elastomers, which are elastic and usually very soft, they cannot fully meet the support requirements at the coolant inlet and outlet, and may cause collapse of the inlet and outlet under some operating conditions, resulting in a significant drop in coolant pressure.
[0006] Therefore, given the many shortcomings of the existing technology, there is still a need to improve the above-mentioned technical solutions. Utility Model Content

[0072] To make the technical problems to be solved, the technical solutions, and the beneficial technical effects of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and several exemplary embodiments. It should be understood that the specific embodiments described herein are only for explaining this application and are not intended to limit the scope of protection of this application.
[0073] Where there is no conflict, features in the embodiments of this application can be combined with each other. In different drawings, the same components are represented by the same reference numerals, and other components are omitted for brevity, but this does not mean that the technical solution of this application cannot include other components. It should be understood that the dimensions, scale relationships, and number of components in the drawings are not intended to limit this application.
[0074] The embodiments of this application will now be described in detail with reference to the accompanying drawings.
[0075] Figure 1 A three-dimensional schematic diagram of a fuel cell 1 according to an embodiment of this application is shown.
[0076] According to this embodiment, fuel cell 1 is a proton exchange membrane fuel cell for a vehicle, such as a hydrogen fuel cell, and includes a fuel cell module 2. Fuel cell module 2 includes at least two single-cell components (not shown in detail) stacked on top of each other, and more particularly, multiple single-cell components. In this fuel cell 1, hydrogen and oxygen generate electrical energy through an electrochemical reaction to power the vehicle. Since the basic principles and operating methods of fuel cell 1 are known in the prior art and are not the focus of this application, a detailed description of the basic principles and operating methods of fuel cell 1 is omitted in this application.
[0077] To simplify the description, Figure 1 The diagram also shows the XYZ coordinate system. It should be noted that the XYZ coordinate system is only illustrative of fuel cell 1 in this diagram. Figure 1 The arrangement direction in the diagram does not represent the actual arrangement direction of fuel cell 1 in practical applications. In this XYZ coordinate system, the Z direction represents the stacking direction of the single-cell modules.
[0078] Figure 2 A schematic diagram of a fuel cell module 2 according to an embodiment of this application is shown. Figure 3 It shows Figure 2 A cross-sectional view of fuel cell module 2 in the image.
[0079] According to this embodiment, the fuel cell module 2 includes a plurality of single-cell components stacked on top of each other along the Z direction. Each single-cell component 3, 4 includes at least an anode plate 31, 41, a cathode plate 32, 42, and a membrane electrode 33, 43 (e.g., ...) disposed between the anode plate 31, 41 and the cathode plate 32, 42. Figure 3 (As shown).
[0080] It should be noted that, in Figure 3 For simplicity, only two stacked (adjacent) single-cell components 3 and 4, namely the first single-cell component 3 and the second single-cell component 4, are shown as examples. In the following exemplary description, the technical solution of this application implemented by these two single-cell components 3 and 4 can be applied to two single-cell components that are stacked adjacently in a plurality of single-cell components.
[0081] In this application, "single cell assembly" should be understood as an integral unit that is assembled as an installation unit in the assembly of fuel cell 1.
[0082] Taking the first single-cell module 3 as an example, such as Figure 3 As shown, the first single-cell assembly 3 includes a first anode plate 31, a first cathode plate 32, and a first membrane electrode 33 disposed between the first anode plate 31 and the first cathode plate 32. A first adhesive portion 37 is provided at the edge of the first anode plate 31 and the first cathode plate 32 between them, bonding the edges of the first anode plate 31 and the first cathode plate 32 together to form a single-cell assembly. The first membrane electrode 33 includes a first proton exchange membrane and a first anode gas diffusion layer and a first cathode gas diffusion layer (not shown in detail) located on both sides of the first proton exchange membrane. Furthermore, a first anode gas flow field 35 is constructed on the side of the first anode plate 31 facing the membrane electrode 33. A first cathode gas flow field 36 is constructed on the side of the first cathode plate 32 facing the membrane electrode 33. Anode gas, such as hydrogen, can be introduced via the end of the first single-cell assembly 3 (at... Figure 2 The anode gas inflow channel 12, constructed at the left end (middle), enters the first anode gas flow field 35 and flows from the other end of the first single cell assembly 3, away from that end (in the middle). Figure 2 The anode gas exit channel 13, constructed at the right end of the first battery assembly 3, flows out. Cathode gas, such as oxygen or air, can enter the first cathode gas flow field 36 via the cathode gas inlet channel 14 constructed at this end of the first battery assembly 3 and exit from the cathode gas outlet channel 15 constructed at the other end (see also...). Figure 2 ).
[0083] Similarly, the second single-cell assembly 4 includes a second anode plate 41, a second cathode plate 42, and a second membrane electrode 43 disposed between the second anode plate 41 and the second cathode plate 42. The second membrane electrode 43 includes a second proton exchange membrane and a second anode gas diffusion layer and a second cathode gas diffusion layer (not shown in detail) located on both sides of the second proton exchange membrane.
[0084] In this embodiment, such as Figure 3 As shown, a first seal 34 and a second seal 44 are respectively constructed on the periphery of the first cathode plate 32 of the first single-cell assembly 3 and the periphery of the second cathode plate 42 of the second single-cell assembly 4. In the stacked arrangement, the first anode plate 31 of the first single-cell assembly 3 faces the second cathode plate 42 of the second single-cell assembly 4. Therefore, the second seal 44 of the second single-cell assembly 4 seals and presses against the periphery of the first anode plate 31 of the first single-cell assembly 3.
[0085] Figure 4 It shows Figure 2 BB cross-sectional view of fuel cell module 2 in the image.
[0086] Also refer to Figure 2 and Figure 3 To cool the fuel cell module 2, a coolant flow field 5 is formed between the first anode plate 31 and the second cathode plate 42 in the stacked arrangement (see...). Figure 3 And forms an inlet 6 for coolant to flow into the coolant flow field 5 and an outlet 7 for coolant to flow out of the coolant flow field 5 (see...). Figure 2 Coolant, such as water, can be supplied via, for example, at the end of the first single-cell assembly 3 (in...). Figure 2 The coolant inflow channel 9, constructed at the left end (middle), flows through the inlet 6 (as in...). Figure 4 (As shown in the dashed box) flows into the coolant flow field 5 (as shown in...) Figure 4 The direction of coolant flow (F, indicated by dashed lines) is, for example, from the other end of the first single-cell assembly 3, away from that end (in... Figure 2 The coolant flows out through the coolant outlet channel 10 constructed at the right end of the middle section, thereby enabling the cooling of the first anode plate 31 or anode side of the first single cell assembly 3 and the second cathode plate 42 or cathode side of the second single cell assembly 4.
[0087] Similarly, in the case of multiple single-cell modules, a coolant flow field 5 is formed between every two adjacent single-cell modules.
[0088] In a stacked arrangement, seals 34 and 44 not only seal the coolant, or rather, the coolant flow field 5, but also partially support the individual cell assembly. However, since seals 34 and 44 are typically made of rubber or polymer elastomers, the stacking pressure may cause them to fail to fully meet the support requirements at the inlet 6 and outlet 7. Furthermore, under certain operating conditions, this may lead to the collapse of the inlet 6 and outlet 7, resulting in a significant decrease in coolant pressure.
[0089] Therefore, according to one embodiment of this application, a support portion 8 is constructed from a first anode plate 31 and / or a second cathode plate 42, which is suitable for supporting at least two single cell assemblies 3, 4 in the inlet 6 and / or outlet 7.
[0090] Figure 5 It shows Figure 4 A partial view of the fuel cell module 2 shows a first embodiment of the support portion 8. For clarity, the support portions 8 of the first anode plate 31 and the second cathode plate 42 are labeled "311" and "421" respectively, namely the first support portion 311 and the second support portion 421. Furthermore, in Figure 5 The inlet 6 is shown as an example.
[0091] In this embodiment, the first support portion 311 is configured as a shaped portion protruding from the plate plane of the first anode plate 31 along the stacking direction Z, and the second support portion 421 is configured as a shaped portion protruding from the plate plane of the second cathode plate 42.
[0092] like Figure 5 As shown, the first support portion 311 and the second support portion 421 are respectively constructed as die-cast portions formed by die-casting the first anode plate 31 and the second cathode plate 42, and the die-cast portions are constructed as solid cylindrical shapes. Furthermore, the first support portion 311 and the second support portion 421 are constructed identically to each other, and in a stacked arrangement, the first support portion 311 of the first anode plate 31 and the second support portion 421 of the second cathode plate 42 are oriented towards each other and supported on each other. Thus, reliable support between the two single-cell assemblies 3 and 4 can be achieved at the inlet 6, thereby preventing the collapse of the inlet 6 and the resulting drop in coolant pressure. The same construction and function also apply to the outlet 7 (see...). Figure 2 ).
[0093] According to one embodiment, the first anode plate 31 and the second cathode plate 42 are respectively constructed as metal plates. Therefore, the first support portion 311 and the second support portion 421 are also constructed as metal support portions. Due to the metal material, the supporting effect can be further enhanced, thereby further preventing the collapse of the inlet 6 and / or the outlet 7.
[0094] Further as Figure 5 As shown, the first support portion 311 and the second support portion 421 are constructed as surface supports and, for example, form a planar support portion 82. This allows for a uniform distribution of the supporting force within the support portion 82.
[0095] According to one embodiment, see also Figure 2 and Figure 4 Multiple support sections 8 are constructed in the inlet 6 and outlet 7, and are arranged spaced apart from each other. This forms multiple sub-inlets of the inlet 6 and multiple sub-outlets of the outlet 7 between the support sections 8, thereby ensuring reliable flow of coolant into and out of the coolant flow field 5. The multiple support sections 8 are arranged along the cross-sectional direction of the inlet 6 and outlet 7, or in other words, along the Y-direction.
[0096] Figure 6 It shows Figure 5 A diagram showing a first variation of the support portion 8. (And...) Figure 5 Unlike the previous support portion 8, the support portion 8, or the first support portion 311 and the second support portion 421, are stamped portions formed by the first anode plate 31 and the second cathode plate 42, respectively. Consequently, corresponding stamped slots 81, namely the first stamped slot 312 and the second stamped slot 422, are constructed in the first support portion 311 and the second support portion 421. This increases the cross-sectional area of the coolant flowing in from the inlet 6 and out from the outlet 7, thereby increasing the coolant flow rate and further ensuring the cooling effect.
[0097] Figure 7 It shows Figure 5 The diagram shows a second embodiment of the support portion 8. The first support portion 311 and the second support portion 421 are also constructed identically. Figure 5 The difference between the support portion 8 and the first support portion 311 and the second support portion 421 is that the first support portion 311 and the second support portion 421 each have a convex end, the convex ends support each other and form a linear support at the support portion 82. Thus, compared with... Figure 5 This also correspondingly increases the cross-section of the coolant flowing in from the inlet 6 and out from the outlet 7, thereby increasing the coolant flow rate and further ensuring the cooling effect.
[0098] Figure 8 It shows Figure 7 A diagram showing a second variation of the support portion 8. (And...) Figure 6Similarly, the support portion 8, or the first support portion 311 and the second support portion 421, are also stamped portions formed by stamping the first anode plate 31 and the second cathode plate 42, respectively. Therefore, with Figure 7 In contrast, corresponding stamping slots 81, namely the first stamping slot 312 and the second stamping slot 422, are constructed in the first support portion 311 and the second support portion 421. This further increases the cross-section of the coolant flowing in from the inlet 6 and out from the outlet 7, thereby further increasing the coolant flow rate and further ensuring the cooling effect.
[0099] Figure 9 It shows Figure 5 A diagram illustrating a third embodiment of the support portion 8. (Compared to...) Figures 5 to 8 The support portion 8 is different from that of the first support portion 311 and the second support portion 421. In this embodiment, the support portion 8, or the first support portion 311 and the second support portion 421, are constructed differently.
[0100] like Figure 9 As shown, the first support portion 311 exemplarily has a convex end, and the second support portion 421 exemplarily has a concave end that mates with the convex end of the first support portion 311. Thus, a curved support is formed at the support portion 82. This achieves a more uniform distribution of the supporting force at the support portion 82, and also improves the tolerance of the fit between the first support portion 311 and the second support portion 421 when multiple single-cell assemblies are stacked, thereby simplifying assembly.
[0101] Figure 10 It shows Figure 9 A diagram illustrating the third variation of the support portion 8. Similar to... Figure 6 and Figure 8 Support part 8 in the middle, Figure 10 The support portion 8, or the first support portion 311 and the second support portion 421, are also stamped portions formed by the first anode plate 31 and the second cathode plate 42, respectively. Therefore, corresponding stamping slots 81, namely the first stamping slot 312 and the second stamping slot 422, are constructed in the first support portion 311 and the second support portion 421. Thus, compared to... Figure 9 , Figure 10 This modified version of the support portion 8 further increases the cross-section of the coolant flowing in from the inlet 6 and out from the outlet 7, thereby further increasing the coolant flow rate and further ensuring the cooling effect.
