Description

Technical Field

[0001] The present application relates to the technical field of high-temperature solid oxide battery (SOC) stacks, and provides a parametric design method, device, and equipment for a connector flow channel. Background Art

[0002] As we all know, there are many different designs of metal connectors for high-temperature solid oxide cell (SOC) stacks, such as Figure 1 The figure shows a common "cross-channel" connector. The connector has rectangular main gas channels on its left and right sides for fuel gas flow. These channels connect to the fuel gas inlet and outlet on the stack's hot box. During stack operation, fuel gas first enters the main gas channel on the right, then enters each reaction zone channel. After undergoing electrochemical reaction, it flows out of the reaction zone channel on the left and converges with the main gas channel on the left, ultimately exiting the stack. Air enters the reaction zone of the stack from the rear and exits from the front. The flow of fuel gas and air forms a cross pattern.

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other in any way.

[0062] Glossary:

[0063] High-temperature solid oxide battery SOC is a general term for high-temperature solid oxide fuel cells (Solid Oxide Fuel Cell, SOFC) and high-temperature solid oxide electrolysis cells (Solid Oxide Electrolysis Cell, SOEC). Generally, an SOC stack is composed of a plurality of identical single battery cells stacked together, wherein each single battery cell is composed of a single battery cell, a metal connector and a sealing material. The single battery cell is composed of an anode, a cathode and an electrolyte; the metal connector is another core component of the SOC stack, through which the anode and cathode of adjacent battery cells can be connected, thereby playing a role in electrical and thermal conductivity. In addition, the metal connector can also separate the hydrogen and water vapor on both sides of the battery cell from the air and oxygen. The single battery cells are connected by a sealing assembly.

[0064] As we all know, there are many different designs of metal connectors for high-temperature solid oxide cell (SOC) stacks, such as Figure 1 The figure shows a common "cross-channel" connector. The connector has rectangular main gas channels on its left and right sides for fuel gas flow. These channels connect to the fuel gas inlet and outlet on the stack's hot box. During stack operation, fuel gas first enters the main gas channel on the right, then enters each reaction zone channel. After undergoing electrochemical reaction, it flows out of the reaction zone channel on the left and converges with the main gas channel on the left, ultimately exiting the stack. Air enters the reaction zone of the stack from the rear and exits from the front. The flow of fuel gas and air forms a cross pattern.

[0065] Existing research shows that the geometry of the connector flow channel has a significant impact on fuel cell performance. Specific flow channel shapes include rectangular, circular, trapezoidal, and arched. However, existing connector flow channel designs suffer from low modeling and simulation efficiency and poor flow channel performance.

[0066] Based on this, the embodiment of the present application provides a parametric design method for a connector flow channel, in which, first, the connector arch flow channel to be designed can be split into multiple flow channel curves; then, for any flow channel curve, a parametric equation corresponding to any flow channel curve can be defined; finally, the characteristic parameters in the parametric equation can be optimized to obtain the optimized flow channel curve corresponding to any flow channel curve. Therefore, in the present application, since the corresponding parametric equations are defined for each segment of the split flow channel curve, and the optimized flow channel curve corresponding to each segment of the flow channel curve is obtained by optimizing the characteristic parameters in the parametric equation, compared with the existing connector flow channel design scheme, the present application can more clearly understand what parameters (or what kind of flow channel linear shape) have a significant impact on the performance of the battery stack through the study of linear parameters, thereby greatly improving the flow channel performance of the designed connector flow channel. In addition, such a parametric design also greatly shortens the time required for design, modeling, and simulation, and is also more conducive to subsequent optimization using methods such as sensitivity analysis and DOE experimental design.

[0067] After introducing the design concepts of the embodiments of the present application, the following briefly introduces the application scenarios to which the technical solutions of the embodiments of the present application can be applied. It should be noted that the application scenarios introduced below are only used to illustrate the embodiments of the present application and are not limiting. In the specific implementation process, the technical solutions provided by the embodiments of the present application can be flexibly applied according to actual needs.

[0068] like Figure 2 As shown, an electronic device provided in an embodiment of the present application, the electronic device can specifically be a parametric design device 20 for a connector flow channel.

[0069] The parametric design device 20 for a connector flow channel can be used to perform parametric design on a connector arcuate flow channel. For example, it can be a personal computer (PC), a server, or a laptop. The parametric design device 20 for a connector flow channel can include one or more processors 201, a memory 202, an I / O interface 203, and a database 204. Specifically, the processor 201 can be a central processing unit (CPU) or a digital processing unit. The memory 202 can be a volatile memory, such as a random-access memory (RAM); a non-volatile memory, such as a read-only memory, a flash memory, a hard disk drive (HDD), or a solid-state drive (SSD); or any other medium capable of carrying or storing desired program code in the form of instructions or data structures and accessible by a computer, but not limited thereto. Memory 202 may be a combination of the aforementioned memories. Memory 202 may store some program instructions for the parametric design method for the connector flow channel provided in the embodiments of the present application. These program instructions, when executed by processor 201, can be used to implement the steps of the parametric design method for the connector flow channel provided in the embodiments of the present application, thereby addressing the low modeling and simulation efficiency and poor flow channel performance issues of existing connector flow channel design solutions. Database 204 may be used to store data such as parametric equations, optimized flow channel curves, curvatures, and characteristic parameters involved in the solutions provided in the embodiments of the present application.

[0070] In the embodiment of the present application, the parametric design device 20 for the connector flow channel can obtain characteristic parameters corresponding to each parametric equation through the I / O interface 203. Then, the processor 201 of the parametric design device 20 for the connector flow channel can improve modeling and simulation efficiency and flow channel performance according to the program instructions of the parametric design method for the connector flow channel provided in the embodiment of the present application in the memory 202. In addition, data such as the parametric equations, optimized flow channel curves, curvatures, and characteristic parameters can also be stored in the database 204.

[0071] Of course, the method provided in the embodiment of the present application is not limited to Figure 2 The application scenarios shown can also be used in other possible application scenarios, and the embodiments of this application are not limited thereto. Figure 2The functions that can be realized by each device in the application scenario shown will be described in the subsequent method embodiments, and will not be described in detail here.

[0072] like Figure 3 FIG. 1 is a schematic diagram of a parameterized design method for a connector flow channel according to an embodiment of the present application. The method can be Figure 2 The method is executed by the parametric design device 20 of the connector flow channel. Specifically, the process of the method is introduced as follows.

[0073] Step 301: Split the arcuate flow channel of the connector to be designed into multiple flow channel curves.

[0074] In practical applications, such as Figure 4 The figure shows a schematic diagram of a cross-section of a connector provided by an embodiment of the present application. In one connector, there are multiple repeating flow channel units, and all flow channels have the same shape and a symmetrical structure. Therefore, in the embodiment of the present application, when defining the parametric equation of the flow channel, only half of a single flow channel needs to be defined. Then, by mirroring and arraying the half flow channel line shape, the line shape of the entire flow channel can be obtained.

[0075] Based on this, in the embodiment of the present application, when the arcuate flow channel of the connector to be designed is divided into multiple flow channel curves, the arcuate flow channel of the connector to be designed can be divided into 5 flow channel curves according to the curvature of the arcuate flow channel of the connector to be designed; wherein the 5 flow channel curves include line segment 1, circular arc, line segment 2, elliptical arc and line segment 3 in sequence. Figure 5 FIG. 1 is a schematic diagram of a split arcuate flow channel provided by an embodiment of the present application, wherein the arcuate flow channel of the single-side connector is composed of 5 curve segments, with AB being line segment 1, BC being a circular arc, CD being line segment 2, DE being an elliptical arc, and EF being line segment 3. In addition, Figure 5 In addition to identifying the above-mentioned single-sided connector arched flow channel curve, various curve parameters are also identified.

[0076] Step 302: For any section of the flow channel curve, define a parametric equation corresponding to the any section of the flow channel curve.

[0077] In the embodiment of the present application, if any section of the flow channel curve is line segment 1, that is, Figure 5 For the line segment AB in , the parametric equation is expressed using the following formula (1):

[0078] 0≤θ≤t

[0079] x1=θ

[0080] y1=0 (1)

[0081] Among them, θ is the independent variable of line segment 1; t is the length of line segment 1; x1 and y1 are the horizontal and vertical coordinates of line segment 1 respectively.

[0082] If any section of the flow channel curve is an arc, that is, Figure 5 The parametric equation of the line segment BC is expressed as follows:

[0083]

[0084] Among them, θ is the independent variable of the arc; is the central angle of the arc; x2 and y2 are the horizontal and vertical coordinates of the arc respectively; ρ is the radius of the arc.

[0085] If any section of the flow channel curve is line segment 2, that is, Figure 5 The parametric equation of the line segment CD is expressed as follows:

[0086] 0≤θ≤s

[0087]

[0088] Among them, θ is the independent variable of line segment 2; s is the length of line segment 2; x3 and y3 are the horizontal and vertical coordinates of line segment 2 respectively; un is the inclination angle of line segment 2. Figure 5 As shown, un in formula (2) and formula (3) is the inclination angle of line segment 2, that is, the central angle corresponding to the arc is associated with the inclination angle of line segment 2, thereby ensuring that line segment 2 is on the tangent line of point C of the arc.

[0089] If any section of the flow channel curve is an elliptical arc, that is, Figure 5 The parametric equation of the line segment DE in is expressed as follows:

[0090] θ1≤θ≤θ2

[0091] x4=(e x -e b ·sin(θ))·cos(μ)-(e y -e a ·cos(θ))·sin(μ)

[0092] y4=(e y -e a ·cos(θ))·cos(μ)+(e x -e b ·sin(θ))·sin(μ) (4)

[0093] Among them, θ is the independent variable of the elliptical arc; θ1 and θ2 are the starting angle and ending angle of the elliptical arc respectively; e x 、ey are the x-axis coordinates and y-axis coordinates of the center of the elliptical arc respectively; e a 、e b are the major axis length and minor axis length of the elliptical arc respectively; x4 and y4 are the horizontal coordinate and vertical coordinate of the elliptical arc respectively; μ is the deflection angle between the major axis of the elliptical arc and the y-axis.

[0094] If any section of the flow channel curve is line segment 3, that is, Figure 5 The parametric equation of the line segment EF is expressed as follows:

[0095] 0≤θ≤d

[0096]

[0097] y5=-hc (5)

[0098] Among them, θ is the independent variable of line segment 3; d is the length of line segment 3; bc is the single flow channel width of line segment 3; hc is the flow channel height of line segment 3; x5 and y5 are the horizontal and vertical coordinates of line segment 3 respectively.

[0099] In addition, since the position and normal vector of the connection point of two adjacent flow channel curves are the same, for example, for the connection point of curve BC and curve CD, the position coordinates and normal vector of the last point on curve BC must be the same as the position coordinates and normal vector of the starting point of curve CD. Therefore, in the embodiment of the present application, the curve point at the connection can be expressed using the following formula (6):

[0100]

[0101] Among them, n x Represents the component of the normal vector in the x-axis direction; n y Indicates the component of the normal vector in the y-axis direction; x represents the x-axis coordinate of the curve point; y represents the y-axis coordinate of the curve point. In this application, the above formula (6) can be solved using algebraic methods or numerical methods.

[0102] Step 303: Optimize the characteristic parameters corresponding to the parametric equation to obtain an optimized flow channel curve corresponding to any section of the flow channel curve.

[0103] In an embodiment of the present application, when optimizing the characteristic parameters corresponding to the parametric equation to obtain the optimized flow curve corresponding to any section of the flow curve, first, multiple point clouds corresponding to any section of the flow curve can be generated based on the given different characteristic parameter values; then, multiple flow curves corresponding to any section of the flow curve can be obtained based on these multiple point clouds; finally, the flow curve with the best performance (for example, the maximum fuel gas velocity entering the flow channel, etc.) among the multiple flow curves can be determined as the optimized flow curve corresponding to any section of the flow curve.

[0104] In addition, in order to speed up the parametric design of the connector flow channel, in the embodiment of the present application, the above (1)-(6) and parameter solution method can also be written as an Excel program to reduce manual participation and improve calculation efficiency. Specific embodiment:

[0106] Here, three different parameter settings are introduced in detail as an example, as shown in Table 1 below, which is a parameter setting table provided in an embodiment of the present application.

[0107] Then, by substituting the parameter settings shown in Table 1 into the above formulas (1)-(6) and solving them, the point cloud coordinates of the three linear shapes corresponding to the arcuate flow channel of the single-sided connector to be designed can be obtained, as shown in Table 2 below, which is the point cloud coordinate table provided in the embodiment of the present application. Then, the three flow channel curves corresponding to the arcuate flow channel of the single-sided connector to be designed can be obtained, as shown in Table 2 below. Figure 6 The figure shows a schematic diagram of the cross-sectional linear shape of the flow channel provided in an embodiment of the present application.

[0112] In summary, since the corresponding parametric equations are defined for each segment of the flow channel curve, and the characteristic parameters in the parametric equations are optimized to obtain the optimized flow channel curves corresponding to each segment of the flow channel curve, compared to the existing connector flow channel design scheme, this application can more clearly understand what parameters (or what kind of flow channel linear shape) have a significant impact on the performance of the battery stack through the study of linear parameters, thereby greatly improving the flow channel performance of the designed connector flow channel. In addition, such a parametric design also greatly shortens the time required for design, modeling, and simulation.
