Technical Field

[0001] The present application relates to the technical field of battery power generation systems, and in particular to a battery stack simulation device. Background Art

[0002] Solid Oxide Fuel Cell (SOFC) has many advantages such as quietness, environmental protection, low maintenance cost, wide fuel range, long working life and high efficiency. It is widely used in portable power supplies, distributed power generation / combined heat and power systems, high-performance power supplies, large power stations and other fields.

[0003] Generally, when using a SOFC system, it is necessary to perform cold and hot debugging on it first. However, since the characteristics of the SOFC system need to be obtained through debugging, it is uncertain whether the SOFC system itself can provide conditions that meet the operation of the fuel cell stack. Therefore, it is very likely that the fuel cell stack will be irreversibly damaged due to errors in determining the debugging parameters during the debugging process.

[0004] Therefore, how to avoid damage to the fuel cell stack during the debugging of the SOFC system has become an urgent problem to be solved. Summary of the invention

[0034] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0035] Solid Oxide Fuel Cell (SOFC) has many advantages such as quietness, environmental protection, low maintenance cost, wide fuel range, long working life and high efficiency. It is widely used in portable power supplies, distributed power generation / combined heat and power systems, high-performance power supplies, large power stations and other fields.

[0036] Generally, when using the SOFC system, it needs to be debugged, which is divided into cold debugging and hot debugging. Cold debugging is the flow test and pressure test of the gas circuit and water circuit of the SOFC system before heating up, which preliminarily determines whether the process system can provide the working medium with suitable flow and pressure for the SOFC stack. Hot debugging is the last link of system debugging and the most important part of the entire debugging activity. This test will eventually obtain important parameters such as the system's hot end temperature, pressure, flow, heating rate, temperature difference, etc.

[0037] However, due to the uncertainty of SOFC system design, it is very likely that the stack will be irreversibly damaged due to errors in determining debugging parameters (such as flow, temperature, pressure, etc.) during the debugging process. In addition, since the cost of the stack is very high, once it is damaged, it will significantly affect the system development cost, especially for high-power systems, which are composed of multiple stacks. If the stack is damaged, the economic loss will be several times the relationship. Therefore, how to avoid damage to the stack during the debugging process of the SOFC system has become a problem that needs to be solved urgently. This application aims to solve this problem.

[0038] After the above introduction to the background technology of the battery stack simulation device provided in the embodiment of the present application, the implementation environment involved in the battery stack simulation device provided in the embodiment of the present application will be briefly described below. The battery stack simulation device provided in the embodiment of the present application can be applied in the application environment as shown in Figure 1. Among them, the battery stack test system 01 includes a battery stack simulation device 10 and a test device 20. The battery stack test system 01 is used to test the use condition parameters of a real SOFC battery stack, the battery stack simulation device 10 is used to simulate the performance of a real SOFC battery stack, and can replace the real SOFC battery stack for condition parameter testing, and the test device 20 is used to test the battery stack simulation device 10 or the real SOFC battery stack. It should be noted that the battery stack simulation device 10 can be connected to the test device 20 through multiple groups of interfaces.

[0039] Those skilled in the art will understand that the structure shown in FIG. 1 is merely a block diagram of a partial structure related to the scheme of the present application, and does not constitute a limitation on the application environment to which the scheme of the present application is applied. The specific application environment may include more or fewer components than shown in the figure, or combine certain components, or have a different arrangement of components.

[0040] After introducing the application scenarios of the battery stack simulation device 10 provided in the embodiment of the present application, the following focuses on introducing the battery stack simulation device 10 described in the present application. Figure 2 and Figure 3 As shown, the stack simulation device 10 includes:

[0041] A substrate 101, the geometric parameters of which are consistent with the geometric parameters of a solid oxide fuel cell SOFC stack;

[0042] A first group of interfaces 102 and a second group of interfaces 103, the first group of interfaces 102 and the second group of interfaces 103 are arranged on the same surface of the substrate 101, the first group of interfaces 102 includes a first interface 1021 and a second interface 1022, and the second group of interfaces 103 includes a third interface 1031 and a fourth interface 1032;

[0043] A first flow channel 104 and a second flow channel 105, both of which are disposed in the substrate 101, the first flow channel 104 connects the first interface 1021 and the second interface 1022, and the second flow channel 105 connects the third interface 1031 and the fourth interface 1032;

[0044] The first group of interfaces 102 and the second group of interfaces 103 are connected to a testing device, and the testing device is used to test the stack simulation device 10 .

[0045] It should be noted that in order to enable the stack simulation device 10 to be replaced with a real SOFC stack after the condition parameters are determined, the stack simulation device 10 needs to be consistent with the real SOFC stack in terms of structural shape, interface size, weight, thermal conductivity, specific heat capacity, inlet and outlet pressure drop, etc.

[0046] Optionally, the shape of the substrate 101 may be square, tubular, flat, flat-tube, etc., which is not limited in the embodiment of the present application.

[0047] Among them, the geometric parameters of the SOFC stack are 100mm×100mm×150mm, so the geometric parameters of the substrate are also set to 100mm×100mm×150mm.

[0048] See also Figure 2 and Figure 3In order to make the interface position and shape of the stack simulation device 10 consistent with the interface position and shape of the real SOFC stack, the first interface 1021 and the second interface 1022 in the first group of interfaces 102 are both cylindrical interfaces, the third interface 1031 and the fourth interface 1032 in the second group of interfaces 103 are both square interfaces, and the sizes of the first interface 1021, the second interface 1022, the third interface 1031 and the fourth interface are consistent with the sizes of the real SOFC stack.

[0049] Among them, one of the first interface 1021 and the second interface 1022 is a medium inlet, and the other is a medium outlet; one of the third interface 1031 and the fourth interface 1032 is a medium inlet, and the other is a medium outlet.

[0050] See also Figure 2 and Figure 3 The first flow channel 104 is arranged in the base 101, and is used to connect the first interface 1021 and the second interface 1022. That is, when the stack simulation device 10 is connected to the test equipment 20, and the first interface 1021 is the medium inlet and the second interface 1022 is the medium outlet, the medium in the test equipment 20 is connected through the first interface 1021, passes through the first flow channel 104, and is connected through the second interface 1022. The test equipment 20 determines the first operating parameter of the stack simulation device 10 according to the first connected medium information and the first disconnected medium information.

[0051] See also Figure 2 and Figure 3 The second flow channel 105 is arranged in the base 101, and is used to connect the third interface 1031 and the fourth interface 1032. That is, when the stack simulation device 10 is connected to the test equipment 20, and the third interface 1031 is the medium inlet, and the fourth interface 1032 is the medium outlet, the medium in the test equipment 20 is connected through the third interface 1031, passes through the second flow channel 105, and is connected through the third interface 1032. The test equipment 20 determines the second operating parameters of the stack simulation device 10 according to the second connected medium information and the second connected medium information.

[0052] Furthermore, the final operating parameters of the fuel cell simulation device 10 are determined according to the first operating parameters of the fuel cell simulation device 10 and the final operating parameters of the fuel cell simulation device 10 .

[0053] The stack simulation device provided in the embodiment of the present application includes: a substrate, the geometric parameters of the substrate are consistent with the geometric parameters of the solid oxide fuel cell SOFC stack, a first group of interfaces and a second group of interfaces, the first group of interfaces and the second group of interfaces are arranged on the same surface of the substrate, the first group of interfaces include the first interface and the second interface, and the second group of interfaces include the third interface and the fourth interface; a first flow channel and a second flow channel, the first flow channel and the second flow channel are both arranged in the substrate, the first flow channel connects the first interface and the second interface, and the second flow channel connects the third interface and the fourth interface; the first group of interfaces and the second group of interfaces are connected to a test device, and the test device is used to test the stack simulation device. The stack simulation device is designed by geometric parameters, interfaces and flow channels, so that the stack simulation device can replace the real SOFC stack for debugging, avoid damage to the real SOFC stack, and reduce the risk of significant cost increase caused by damage to the real SOFC stack.

[0054] The embodiment of the present application has been applied in the research and development of 20kW-class SOFC power generation system. The system parameters obtained by the cold and hot debugging of the system based on the stack simulation device fully meet the working conditions of the real SOFC stack. The system generates electricity successfully once, and no stack damage caused by the system characteristic parameters exceeding the range occurs during the hot debugging of the real SOFC stack. Since the cost of the real SOFC stack is about 40,000 yuan / unit, and the cost of the stack simulation device is 0.6W yuan / unit, when debugging with the stack simulation device, due to the unreasonable initial adjustment parameter setting, the system temperature rise rate has seriously exceeded the acceptable value of the real SOFC stack. If the debugging is carried out with the real SOFC stack at the beginning, the real SOFC stack has been irreparably damaged, with a direct loss of more than 400,000 yuan (the actual number of installed units is more than ten), while the debugging carried out with the stack simulation device has no direct economic loss, which greatly saves the research and development cost.

[0055] In one embodiment, see Figure 4 The above-mentioned stack simulation device 10 further includes: a hole 106 , and the hole 106 is arranged on any surface of the substrate 101 .

[0056] The holes 106 opened on the substrate 101 connect the interior of the substrate 101 with the outside to prevent the appearance of a high-temperature, high-pressure cavity during the hot debugging of the fuel cell simulation device 10 .

[0057] In the embodiment of the present application, since the real SOFC stack contains a variety of matrix materials such as metal and ceramic, the weight of the stack simulation device 10 may not match the shape and interface size. In this case, the weight can be adjusted by internal material reduction (for example, opening holes on the matrix 101). It should be noted that when the hole 106 is opened, there should be no closed cavity inside the stack simulation device 10 to prevent the occurrence of high temperature and high pressure cavity during hot debugging.

[0058] Among them, since the weight of the real SOFC stack is 15kg, after the hole 106 is opened on the stack simulation device 10, the difference between the total weight of the stack simulation device 10 and 15kg needs to be less than the preset threshold so that the weight of the stack simulation device is close to the weight of the real SOFC stack.

[0059] The stack simulation device provided in the embodiment of the present application has holes opened on the substrate so that the weight of the stack simulation device matches the weight of a real SOFC stack.

[0060] In one embodiment, see Figure 4 The stack simulation device 10 further includes ceramic particles (not shown), which are disposed in the holes 106 .

[0061] Optionally, the ceramic particles may completely fill the entire hole 106 , or may partially fill the entire hole 106 .

[0062] Optionally, since the operating temperature of a real SOFC stack is usually between 600 and 800°C, in order to make the material of the stack simulation device meet the operating temperature requirements, the cheapest material that meets the conditions should be selected. Optionally, the material of the substrate is high temperature resistant stainless steel.

[0063] Optionally, since the real SOFC stack is a composite of multiple materials, the equivalent thermal conductivity and equivalent specific heat capacity of the real stack must first be obtained, and these two parameters must be used to compare the materials of the stack simulation device. When the thermal conductivity and specific heat capacity of a single material differ by more than 10% from those of the real SOFC stack, the stack simulation device can be designed as a composite of multiple materials while taking into account both the appearance and weight. The specific approach can be a combination of subtraction and filling, multi-layer pressing, etc. The volume-weighted average thermal conductivity and volume-weighted average specific heat capacity of the mixed material shall not deviate from the equivalent values ​​of the real stack by more than 10%.

[0064] Among them, since the equivalent thermal conductivity of the real SOFC stack is 6.5W / m·K, the equivalent specific heat capacity is 625J / kg·K, the thermal conductivity of high-temperature resistant stainless steel is 40W / m·K, and the specific heat capacity is 502J / kg·K, if the substrate 101 adopts a single material, namely high-temperature resistant stainless steel, then its thermal conductivity and specific heat capacity deviate greatly from those of the real SOFC stack. Therefore, a combination of subtractive material and filling can be adopted to fill ceramic particles in the hole 106, so that after the volume of the high-temperature resistant stainless steel and the ceramic particles is weighted averaged, the thermal conductivity of the stack simulation device is 6W / m·K, and the average specific heat capacity is 600J / kg·K. It can be seen that the deviation between the thermal conductivity and average specific heat capacity of the stack simulation device and the thermal conductivity and average specific heat capacity of the real SOFC stack are within the preset range, and the total weight of the composite material stack simulation device is 15kg, which is equal to the weight of the real SOFC stack.

[0065] The stack simulation device provided in the embodiment of the present application can make the mass, thermal conductivity and average specific heat of the stack simulation device meet the mass, thermal conductivity and average specific heat of a real SOFC stack by setting holes and ceramic particles on the substrate, so that the operating parameters simulated by the stack simulation device can more accurately reflect the operating parameters of a real SOFC stack. Therefore, when the stack simulation device is used instead of the real SOFC stack for testing, more accurate operating parameters can be obtained.

[0066] In one embodiment, see Figure 2 and Figure 3 The stack simulation device 10 further includes: a first resistance component 107 and a second resistance component 108 . The first resistance component 107 is disposed in the first flow channel 104 , and the second resistance component 108 is disposed in the second flow channel 105 .

[0067] It should be noted that the parameters of the cathode and cathode media of the real SOFC stack are: the second (anode) flow rate is 2.303m3 / h, the medium density is 0.226kg / m3, the medium viscosity is 0.00002892Pa·s, the medium molecular weight is 17.395, the adiabatic index is 1.67, and the temperature is 963K; the first (cathode) flow rate is 24.57m3 / h, the medium density is 0.376kg / m3, the medium viscosity is 0.00004664Pa·s, the medium molecular weight is 28.85, the adiabatic index is 1.4, and the temperature is 963K. The flow pressure drop of the cathode and cathode is 1000Pa.

[0068] In the embodiment of the present application, in order to achieve the above-mentioned anode and cathode medium parameters of the real SOFC stack, a first local resistance component 107 can be set in the first flow channel (cathode flow channel) 104, and a second local resistance component 108 can be set in the second flow channel (anode flow channel) 105 to adjust the pressure drop flowing through the first flow channel and the second flow channel.

[0069] Optionally, the first local resistance component 107 and the second local resistance component 108 can be set to a square structure with a circular hole in the middle, and the size of the circular hole can be adjusted so that the pressure of the medium passing through the first flow channel 104 of the first local resistance component 107 and the second flow channel of the second local resistance component 108 is reduced to 1000Pa.

[0070] Optionally, the size of the first flow channel is 20 mm×20 mm, and the inner diameter of the orifice plate of the first resistance component is 13 mm; the size of the second flow channel is 10 mm×10 mm, and the inner diameter of the orifice plate of the second resistance component is 4 mm. The design of the inner diameter of the orifice plate can adopt the fluid mechanics empirical formula or the CFD method, or a combination of the two to improve the design accuracy.

[0071] It should be noted that in order to make the medium flow resistance of the stack simulation device consistent with that of the real SOFC stack, the medium flow resistance here refers to the inlet and outlet pressure difference of the stack, without considering the flow details of the internal battery cells. This ensures that the medium flow and pressure of the system are basically consistent when debugging with the stack simulation device and the real SOFC stack.

[0072] The stack simulation device provided in the embodiment of the present application can ensure that the medium flow and pressure of the system when debugging the stack simulation device and the real SOFC stack are basically consistent by setting the first resistance component and the second resistance component.

[0073] It should be noted that this embodiment has been applied in the research and development of 20kW-class SOFC power generation systems. The system parameters obtained by cold and hot debugging of the system based on the stack simulation device fully meet the working conditions of the real stack. The system generates electricity successfully once, and no damage to the stack due to the system characteristic parameters exceeding the range occurs during the hot debugging of the real stack. The cost of the real stack is about 40,000 yuan / unit, while the cost of the stack simulation device is 0.6W yuan / unit. When debugging with the stack simulation device, due to the unreasonable setting of the initial adjustment parameters, the system temperature rise rate seriously exceeds the acceptable value of the real stack. If the real stack is debugged at the beginning, the real stack has been irreparably damaged, causing great economic losses. However, the debugging carried out using the stack simulation device has no direct economic losses, which greatly saves the R&D costs.

[0074] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this application.

[0075] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the attached claims.
