[0051] To enable those skilled in the art to better understand the solution of this application, the following will clearly and completely describe the technical solution in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts belong to the scope of protection of this application.

[0052] To make the purpose, technical solution and advantages of this application clearer, the following will further describe the embodiments of this application in detail with reference to the accompanying drawings.

[0053] In a first aspect, an embodiment of this application provides a hydrogen fuel cell control method.

[0054] Figure 1 The flowchart of the hydrogen fuel cell control method in an embodiment of this application is shown.

[0055] Referring to Figure 1 , in an embodiment, the hydrogen fuel cell control method includes the following steps:

[0056] S1. For hydrogen ions and oxygen ions, determine the target change amount at the current moment according to the difference between the target change amount at the current moment and the actual supply amount at the previous moment respectively.

[0057] Specifically, the target supply amount is the demand calculated by the upstream module at each moment, and the actual supply amount is used to control the execution amount of the downstream module at each moment, that is, how much hydrogen ions and oxygen ions are input into the hydrogen fuel cell stack for mixed discharge.

[0058] Exemplarily, for the same kind of ions, the absolute value of the target change amount at the current moment is equal to the absolute value of the difference between the target supply amount at the current moment and the actual supply amount at the previous moment.

[0059] S2. Proportionally limit the target change amount of hydrogen ions and oxygen ions at the current moment according to the maximum supply rate of hydrogen ions and oxygen ions to obtain the theoretical change amount of hydrogen ions and oxygen ions at the current moment.

[0060] Specifically, the maximum supply rate of hydrogen ions and oxygen ions is an inherent parameter of the hydrogen fuel cell, which is obtained through bench test.

[0061] Exemplarily, at the same moment, the absolute value of the ratio of the theoretical change amounts of hydrogen ions and oxygen ions is equal to the absolute value of the ratio of the target change amounts, the absolute value of the theoretical change amount of the same kind of ions is less than or equal to the absolute value of the target change amount, and the absolute value of the theoretical change amount of the same kind of ions is less than or equal to the corresponding maximum supply rate.

[0062] S3. Perform proportional limiting based on the energy efficiency limit value of the hydrogen fuel cell and the conversion parameters of hydrogen ions and oxygen ions and the theoretical change amounts of hydrogen ions and oxygen ions at the current moment to obtain the actual change amounts of hydrogen ions and oxygen ions at the current moment.

[0063] Specifically, the conversion parameters of hydrogen ions and oxygen ions are calibration coefficients, and the energy efficiency limit value of the hydrogen fuel cell is an inherent parameter of the hydrogen fuel cell, which is obtained through bench test.

[0064] Exemplarily, at the same moment, the absolute value of the ratio of the actual change amounts of hydrogen ions and oxygen ions is equal to the absolute value of the ratio of the theoretical change amounts, the absolute value of the theoretical change amount of the same kind of ion is less than or equal to the absolute value of the target change amount, and the sum of the products of the actual change amounts of hydrogen ions and oxygen ions and the corresponding conversion parameters is less than or equal to the energy efficiency limit value of the hydrogen fuel cell.

[0065] S4. For hydrogen ions and oxygen ions, respectively, according to the direction approaching the target supply amount at the current moment, superimpose the actual change amount at the current moment on the actual supply amount at the previous moment to obtain the actual supply amounts of hydrogen ions and oxygen ions at the current moment.

[0066] Exemplarily, for the same kind of ion, the absolute value of the difference between the actual supply amounts at the current moment and the previous moment is equal to the absolute value of the corresponding target change amount, and the actual supply amount at the current moment is closer to the target supply amount at the current moment than the actual supply amount at the previous moment.

[0067] It should be noted that this embodiment mainly focuses on the numerical magnitudes of the target change amount, the theoretical change amount, and the actual change amount, and does not need to pay attention to the positive and negative signs. Therefore, only the absolute value is limited when describing the numerical relationship. In actual operation, it can be adjusted as needed. For example, the absolute values of the calculation results are taken for the target change amount, the theoretical change amount, and the actual change amount, or for another example, the signs of the target change amount, the theoretical change amount, and the actual change amount are the same as the sign of the difference in S1. This embodiment does not make a limitation on this.

[0068] The beneficial effects of this embodiment are proved by the following formula.

[0069] Starting from the current moment, the expected time for the actual supply amounts of hydrogen ions and oxygen ions to change to the target supply amounts is:

[0070]

[0071] Where: Htime represents the expected time for the actual supply of hydrogen ions to change to the target supply from the current moment, Otime represents the expected time for the actual supply of oxygen ions to change to the target supply from the current moment, ΔH represents the target change amount of hydrogen ions at the current moment, ΔH2 represents the actual change amount of hydrogen ions at the current moment, ΔO represents the target change amount of oxygen ions at the current moment, and ΔO2 represents the actual change amount of oxygen ions at the current moment.

[0072] Also because:

[0073]

[0074] Wherein, ΔH1 represents the theoretical change amount of hydrogen ions at the current moment, and ΔO1 represents the theoretical change amount of oxygen ions at the current moment.

[0075] From this, it can be known that

[0076]

[0077] That is: Htime = Otime.

[0078] Therefore, in this embodiment, for hydrogen ions and oxygen ions, at each moment, first, the target change amount at the current moment is determined according to the difference between the target change amount at the current moment and the actual supply amount at the previous moment, then the theoretical change amount at the current moment is obtained by proportionally restricting the target change amount at the current moment from the supply rate level, and then the actual change amount at the current moment is obtained by proportionally restricting the theoretical change amount at the current moment from the energy efficiency level. Finally, the actual change amount at the current moment is superimposed on the actual supply amount at the previous moment in the direction approaching the target supply amount at the current moment to obtain the actual supply amount at the current moment. Through this embodiment, for each moment, the expected time for the actual supply of hydrogen ions and oxygen ions to change to the target supply is equal, thereby ensuring the uniform mixing of hydrogen ions and oxygen ions and improving the discharge energy efficiency of the hydrogen fuel cell.

[0079] Further, in one embodiment, at the same moment, the absolute value of the theoretical change amount of at least one of hydrogen ions and oxygen ions is equal to the corresponding maximum supply rate, or the absolute value of the theoretical change amount of the same kind of ions is equal to the absolute value of the target change amount.

[0080] Through this embodiment, on the premise of meeting the basic conditions of supply rate limitation, the maximization of the theoretical change amount is achieved, thereby increasing the optional range of the actual change amount, and further shortening the time for the actual supply of hydrogen ions and oxygen ions to change to the target supply.

[0081] Further, in one embodiment, step S2 specifically includes:

[0082] Take the absolute value of the ratio of the target change amounts of hydrogen ions and oxygen ions at the current moment as the first ratio at the current moment;

[0083] Take the smaller value between the second ratio and the first ratio at the current moment as the third ratio at the current moment, where the second ratio is equal to the ratio of the maximum supply rates of hydrogen ions and oxygen ions;

[0084] Multiply the maximum supply rate of oxygen ions by the third ratio at the current moment to obtain the restricted change amount of hydrogen ions at the current moment;

[0085] Take the smaller value between the restricted change amount of hydrogen ions at the current moment and the absolute value of the target change amount as the theoretical change amount of hydrogen ions at the current moment;

[0086] Divide the theoretical change amount of hydrogen ions at the current moment by the first ratio at the current moment to obtain the theoretical change amount of oxygen ions at the current moment.

[0087] Exemplarily, assume that the target change amounts of hydrogen ions and oxygen ions at the current moment are 10 and 5 respectively, and the maximum supply rates of hydrogen ions and oxygen ions are 8 and 7 respectively. The first ratio at the current moment is 10 / 5 = 2, the second ratio is 8 / 7, 8 / 7 is less than 2, so the third ratio at the current moment is 8 / 7. The restricted change amount of hydrogen ions at the current moment is 7×(8 / 7) = 8, 8 is less than 10, so the theoretical change amount of hydrogen ions at the current moment is 8, and the theoretical change amount of oxygen ions at the current moment is 8 / 2 = 4.

[0088] Furthermore, in one embodiment, step S2 specifically includes:

[0089] Take the absolute value of the ratio of the target change amounts of hydrogen ions and oxygen ions at the current moment as the first ratio at the current moment;

[0090] Take the larger value between the second ratio and the first ratio at the current moment as the third ratio at the current moment, where the second ratio is equal to the ratio of the maximum supply rates of hydrogen ions and oxygen ions;

[0091] Divide the maximum supply rate of hydrogen ions by the third ratio at the current moment to obtain the restricted change amount of oxygen ions at the current moment;

[0092] Take the smaller value between the restricted change amount of oxygen ions at the current moment and the absolute value of the target change amount as the theoretical change amount of oxygen ions at the current moment;

[0093] Multiply the theoretical change amount of oxygen ions at the current moment by the first ratio at the current moment to obtain the theoretical change amount of hydrogen ions at the current moment.

[0094] Exemplarily, assume that the target change amounts of hydrogen ions and oxygen ions at the current moment are 10 and 5 respectively, and the maximum supply rates of hydrogen ions and oxygen ions are 8 and 7 respectively. The first ratio at the current moment is 10 / 5 = 2, the second ratio is 8 / 7, and 2 is greater than 8 / 7, so the third ratio at the current moment is 2. The limited change amount of oxygen ions at the current moment is 8 / 2 = 4, and 4 is less than 5, so the theoretical change amount of oxygen ions at the current moment is 4, and the theoretical change amount of hydrogen ions at the current moment is 4×2 = 8.

[0095] Further, in one embodiment, step S2 specifically includes:

[0096] Taking the absolute value of the ratio of the target change amounts of oxygen ions and hydrogen ions at the current moment as the first ratio at the current moment;

[0097] Taking the smaller value of the second ratio and the first ratio at the current moment as the third ratio at the current moment, where the second ratio is equal to the ratio of the maximum supply rates of oxygen ions and hydrogen ions;

[0098] Multiplying the maximum supply rate of hydrogen ions by the third ratio at the current moment to obtain the limited change amount of oxygen ions at the current moment;

[0099] Taking the smaller value of the absolute value of the limited change amount of oxygen ions and the target change amount at the current moment as the theoretical change amount of oxygen ions at the current moment;

[0100] Dividing the theoretical change amount of oxygen ions at the current moment by the first ratio at the current moment to obtain the theoretical change amount of hydrogen ions at the current moment.

[0101] Exemplarily, assume that the target change amounts of hydrogen ions and oxygen ions at the current moment are 10 and 5 respectively, and the maximum supply rates of hydrogen ions and oxygen ions are 8 and 7 respectively. The first ratio at the current moment is 5 / 10 = 1 / 2, the second ratio is 7 / 8, and 1 / 2 is less than 7 / 8, so the third ratio at the current moment is 1 / 2. The limited change amount of oxygen ions at the current moment is 8×(1 / 2) = 4, and 4 is less than 5, so the theoretical change amount of oxygen ions at the current moment is 4, and the theoretical change amount of hydrogen ions at the current moment is 4 / (1 / 2) = 8.

[0102] Further, in one embodiment, step S2 specifically includes:

[0103] Taking the absolute value of the ratio of the target change amounts of oxygen ions and hydrogen ions at the current moment as the first ratio at the current moment;

[0104] Taking the larger value of the second ratio and the first ratio at the current moment as the third ratio at the current moment, where the second ratio is equal to the ratio of the maximum supply rates of oxygen ions and hydrogen ions;

[0105] Dividing the maximum supply rate of oxygen ions by the third ratio at the current moment gives the restricted change amount of hydrogen ions at the current moment;

[0106] Taking the smaller value between the restricted change amount of hydrogen ions at the current moment and the absolute value of the target change amount as the theoretical change amount of hydrogen ions at the current moment;

[0107] Multiplying the theoretical change amount of hydrogen ions at the current moment by the first ratio at the current moment gives the theoretical change amount of oxygen ions at the current moment.

[0108] Exemplarily, assume that the target change amounts of hydrogen ions and oxygen ions at the current moment are 10 and 5 respectively, and the maximum supply rates of hydrogen ions and oxygen ions are 8 and 7 respectively. The first ratio at the current moment is 5 / 10 = 1 / 2, the second ratio is 7 / 8, and since 7 / 8 is greater than 1 / 2, the third ratio at the current moment is 7 / 8. The restricted change amount of hydrogen ions at the current moment is 7 / (7 / 8) = 8, and since 8 is less than 10, the theoretical change amount of hydrogen ions at the current moment is 8, and the theoretical change amount of oxygen ions at the current moment is 8×(1 / 2) = 4.

[0109] It can be seen that although the calculation steps of the above four embodiments are different, the finally calculated theoretical change amounts are the same, all achieving the maximization of the theoretical change amount.

[0110] Further, in one embodiment, step S3 specifically includes:

[0111] Multiplying the absolute values of the theoretical change amounts of hydrogen ions and oxygen ions at the current moment by the corresponding conversion parameters and summing them to obtain the converted energy efficiency value at the current moment;

[0112] If the converted energy efficiency value at the current moment is less than the energy efficiency limit value of the hydrogen fuel cell, determine that the change coefficient at the current moment is equal to 1, otherwise divide the converted energy efficiency value at the current moment by the energy efficiency limit value of the hydrogen fuel cell to obtain the change coefficient at the current moment;

[0113] Multiplying the theoretical change amounts of hydrogen ions and oxygen ions at the current moment by the change coefficient at the current moment respectively to obtain the actual change amounts of hydrogen ions and oxygen ions at the current moment.

[0114] Through this embodiment, on the premise of meeting the basic conditions of the energy efficiency limit, the maximization of the actual change amount is achieved, thereby shortening the time for the actual supply amounts of hydrogen ions and oxygen ions to change to the target supply amounts.

[0115] Exemplarily, the calculation formula for the converted energy efficiency value at the current moment is:

[0116] δ1 = ε1*|ΔH1| + ε2*|ΔO1|

[0117] Among them, δ1 represents the converted energy efficiency value at the current moment, ΔH1 represents the theoretical change amount of hydrogen ions at the current moment, ΔO1 represents the theoretical change amount of oxygen ions at the current moment, ε1 represents the conversion parameter of hydrogen ions, and ε2 represents the conversion parameter of oxygen ions.

[0118] The calculation formula for the change coefficient at the current moment is:

[0119]

[0120] Among them, δ1 represents the change coefficient at the current moment, and δmax represents the energy efficiency limit value of the hydrogen fuel cell.

[0121] The calculation formula for the actual change amounts of hydrogen ions and oxygen ions at the current moment is:

[0122]

[0123] Among them, ΔH2 represents the actual change amount of hydrogen ions at the current moment, and ΔO2 represents the actual change amount of oxygen ions at the current moment.

[0124] Further, in one embodiment, step S4 specifically includes:

[0125] If the target supply amount of hydrogen ions at the current moment is greater than the actual supply amount at the previous moment, then add the absolute value of the actual change amount at the current moment to the actual supply amount of hydrogen ions at the previous moment to obtain the actual supply amount of hydrogen ions at the current moment; otherwise, subtract the absolute value of the actual change amount at the current moment from the actual supply amount of hydrogen ions at the previous moment to obtain the actual supply amount of hydrogen ions at the current moment;

[0126] If the target supply amount of oxygen ions at the current moment is greater than the actual supply amount at the previous moment, then add the absolute value of the actual change amount at the current moment to the actual supply amount of oxygen ions at the previous moment to obtain the actual supply amount of oxygen ions at the current moment; otherwise, subtract the absolute value of the actual change amount at the current moment from the actual supply amount of oxygen ions at the previous moment to obtain the actual supply amount of oxygen ions at the current moment.

[0127] Through this embodiment, regardless of whether the original signs are retained during the calculation of the target change amount, theoretical change amount, and actual change amount, it can ensure that the calculation direction is towards the direction of approaching the target supply amount at the current moment.

[0128] Exemplarily, the calculation formula for the actual supply amounts of hydrogen ions and oxygen ions at the current moment is:

[0129]

[0130] Among them, H(K) represents the actual supply amount of hydrogen ions and oxygen ions at the current moment, O(K) represents the actual supply amount of oxygen ions and oxygen ions at the current moment, H(K - 1) represents the actual supply amount of hydrogen ions and oxygen ions at the previous moment, O(K - 1) represents the actual supply amount of oxygen ions and oxygen ions at the previous moment, SH represents the sign flag of hydrogen ions at the current moment, SO represents the sign flag of oxygen ions at the current moment, ΔH2 represents the actual change amount of hydrogen ions at the current moment, and ΔO2 represents the actual change amount of oxygen ions at the current moment.

[0131] The calculation formula for the sign flags of hydrogen ions and oxygen ions at the current moment is:

[0132]

[0133] Among them, Htarget is the target supply amount of hydrogen ions at the current moment, and Otarget is the target supply amount of oxygen ions at the current moment.

[0134] In a second aspect, an embodiment of the present application further provides a hydrogen fuel cell control device.

[0135] Figure 2 The schematic diagram of the functional modules of the hydrogen fuel cell control device in an embodiment of the present application is shown.

[0136] Referring to Figure 2 , in an embodiment, the hydrogen fuel cell control device includes:
