[0028] Please refer to Figure 1 As shown, the present application provides an electrolyzer performance test and evaluation method, which can be used to evaluate the comprehensive performance of the electrolyzer, so as to determine whether the quality of the electrolyzer is qualified / unqualified. Specifically, the performance test of the electrolyzer includes the test of the basic performance and process performance of the electrolyzer, and the performance test indicators of the electrolyzer mainly include basic condition data (basic performance) and process performance data (process performance), wherein the basic condition data include the electrolyzer water inlet temperature, the electrolyzer water inlet pressure, the electrolyzer water inlet flow, the electrolyzer water inlet conductivity and the electrolyzer hydrogen outlet pressure; the process performance data include the output hydrogen flow, the cell voltage, the electrolyzer current, the total voltage of the electrolyzer, the oxygen content in hydrogen, the hydrogen content in oxygen, the average cell voltage, the voltage deviation of each cell and the DC unit energy consumption of the electrolyzer.

[0029] In this application, the electrolytic cell performance test and evaluation method comprises the following steps:

[0030] S1: Obtaining a first reference interval for evaluating basic performance of the electrolytic cell and a second reference interval for evaluating process performance;

[0031] S2: Acquire first real-time data corresponding to the test conditions of the tested electrolytic cell and second real-time data of the test process;

[0032] S3: If all the first real-time data fall within the corresponding first reference interval, and all the second real-time data fall within the corresponding second reference interval, it is determined that the performance of the electrolytic cell is qualified and the electrolytic cell under test is of the first quality;

[0033] If at least one first real-time data falls outside the first reference interval, and / or at least one second real-time data falls outside the second reference interval, the performance of the electrolytic cell is determined to be an undetermined abnormality.

[0034] Further, the electrolytic cell with the abnormality is further tested, including the following steps:

[0035] Acquire a first deviation interval and a second deviation interval, wherein the first reference interval falls within the first deviation interval, and the second reference interval falls within the second deviation interval;

[0036] Compare the first real-time data and the second real-time data of the electrolytic cell determined to be abnormal with the first deviation interval and the second deviation interval respectively;

[0037] If the first real-time data falls outside the first reference interval and falls within the first deviation interval, it is determined that the basic performance of the electrolytic cell is abnormal; if the first real-time data falls outside the first deviation interval, it is determined that the basic performance of the electrolytic cell is abnormal;

[0038] If the second real-time data falls outside the second reference interval and falls within the second deviation interval, it is determined that the process performance of the electrolytic cell is abnormal; if the second real-time data falls outside the second deviation interval, it is determined that the process performance of the electrolytic cell is abnormal;

[0039] Calculate the sum of the pending abnormality times of the basic performance and process performance of the electrolytic cell. If the ratio of the sum of the pending abnormality times to the preset total sampling times is greater than the set ratio, the electrolytic cell performance is judged to be unqualified and the test is stopped immediately; if the ratio of the sum of the pending abnormality times to the preset total sampling times is less than or equal to the set ratio, the electrolytic cell performance is judged to be qualified and the electrolytic cell under test is of the second quality.

[0040] In some embodiments, the electrolytic cell performance test and evaluation method may include the following steps:

[0041] Obtaining a first reference interval of basic condition data and a second reference interval of process performance data of the electrolytic cell under the same test conditions; wherein the first reference interval and the second reference interval are, for example, set fixed value ranges or fitted model data;

[0042] A test platform is provided, and an electrolytic cell is installed on the test platform. The test platform can be used to test, analyze, and evaluate the electrolytic cell. After the test platform is in steady-state operation, first real-time data of basic condition data and second real-time data of process performance data under the same test conditions of the electrolytic cell at the same time interval ti are obtained; for example, the real-time data of the electrolytic cell inlet water temperature T is Ti, and the real-time data of the electrolytic cell inlet water pressure P is Pi;

[0043] Compare each of the first real-time data with the corresponding first reference interval. If all the first real-time data fall within the first reference interval, the basic performance Qi of the electrolytic cell at time point ti is normal; if at least one of the first real-time data falls outside the first reference interval and falls within the first deviation interval, the basic performance Qi of the electrolytic cell at time point ti is abnormal; if at least one of the first real-time data falls outside the first deviation interval or belongs to other situations, the basic performance Qi of the electrolytic cell at time point ti is abnormal;

[0044] Compare each item of the second real-time data with the corresponding second reference interval respectively. If all the second real-time data fall within the second reference interval respectively, the process performance Di of the electrolytic cell at time point ti is normal; if at least one item of the second real-time data falls outside the second reference interval and falls within the second deviation interval, the process performance Di of the electrolytic cell at time point ti is pending abnormal; if at least one item of the second real-time data falls outside the second deviation interval or belongs to other situations, the process performance Di of the electrolytic cell at time point ti is abnormal;

[0045] If the ratio of the sum of the pending abnormal times of the basic performance Qi and the process performance Di to the preset total sampling times exceeds the set ratio, and the range of the set ratio is, for example, 8%-13%, the electrolytic cell performance is determined to be unqualified, and the test is stopped immediately; if the ratio of the sum of the pending abnormal times to the preset total sampling times is less than or equal to the set ratio, the electrolytic cell performance is determined to be qualified, and the electrolytic cell under test is of the second quality; if the basic performance Qi and the process performance Di are both normal, the electrolytic cell performance is determined to be qualified, and the electrolytic cell under test is of the first quality;

[0046] Wherein, i is the sampling number of the test platform, that is, the number of time intervals of a single test of the electrolytic cell. After the test platform is in steady state operation, sampling and testing will be automatically started. The duration of a single test is not less than 8 hours, the total test time is not less than 24 hours, and the interval time ti during the test is not less than 1 hour, for example, it is set to 1 hour. The second real-time data includes the output hydrogen flow rate, the cell voltage, the average cell voltage, the voltage deviation of each cell, the electrolytic cell current, the oxygen content in hydrogen, the hydrogen content in oxygen and the DC unit energy consumption of the electrolytic cell. There are multiple electrolytic cells, and the cell voltages of multiple electrolytic cells need to be tested. Therefore, the second real-time data includes the cell voltages 1…n. The first reference interval and the second reference interval are fixed numerical ranges; the first deviation interval and the second deviation interval are, for example, empirical values ​​derived from experience, such as the maximum deviation degree of the first deviation interval is 3%-5% of the end value of the first reference interval, and the maximum deviation degree of the second deviation interval is 3%-5% of the end value of the second reference interval.

[0047] The present application also provides an electrolytic cell performance test control system, which can perform performance test and evaluation on the electrolytic cell according to the evaluation method described above. Specifically, the control system includes a test module, a data processing module, a data detection module, a power module and a communication module, the power module provides power supply for the control system, the test module provides a test platform for the electrolytic cell, the data detection module is used to perform performance test on the electrolytic cell installed on the test platform, the data processing module is used to analyze the data detected by the data detection module, and the communication module is used to connect with the communication device signal to realize data transmission between the control system and the communication device.

[0048] The electrolytic cell performance test and evaluation method of the present application is based on the comparison of basic condition data and process performance data with the corresponding reference interval, and it is concluded that the basic performance and process performance of the electrolytic cell are in normal, pending abnormal or abnormal states, and further determines whether the electrolytic cell performance is qualified and the specific quality level of the qualified state according to the proportion of the sum of the number of pending abnormalities. The evaluation method is simple and reliable, with a short test cycle and high accuracy, and the control system can realize automatic test data, automatic analysis of data, and then automatically determine whether the product is qualified / unqualified, effectively shortening the test cycle of the electrolytic cell, improving test efficiency and test accuracy, reducing the manual tedious recording and analysis of data, and improving the effectiveness and accuracy of test data.

[0049] Preferably, the evaluation method further comprises:

[0050] After determining that the performance of the electrolytic cell is unqualified and the test is immediately stopped, the unqualified electrolytic cell is manually tested, and whether the performance of the electrolytic cell is qualified or not is based on the result of the manual test.

[0051] The electrolytic cell judged as the second quality is retested. If the judgment result obtained from the retest is still the second quality, a final determination result of the second quality of the electrolytic cell is given; if the judgment result obtained from the retest is the first quality, the electrolytic cell is changed to the first quality.

[0052] After acquiring the detection data, the data processing module generates a performance comparison curve chart of the electrolytic cell, for example, generates a performance comparison curve chart of the electrolytic cell at different time points ti, and generates a performance comparison curve chart for each test data.

[0053] After the test is completed, a test report is automatically generated, which presents the test data and judgment results.

[0054] In some embodiments, the test platform can be provided with multiple test channels. For example, 8 test channels are provided in this embodiment, and eight channels can be started and tested simultaneously with one button. At least one electrolytic cell can be installed on each test channel, for example, one electrolytic cell is installed on one test channel.

[0055] Specifically, multiple channels can be tested for performance at the same time. After the multi-channel test is completed, the data processing module automatically generates a multi-channel performance comparison curve of the electrolytic cell, for example, a multi-channel performance comparison curve of the electrolytic cell at different ti time points is generated, and the same test data of the electrolytic cell of multiple channels generates a multi-channel performance comparison curve; after the multi-channel test is completed, the data processing module automatically generates a test report, and the test report presents the test data and judgment results of multiple channels respectively, so as to realize the automatic generation of reports of the test data of the electrolytic cell, realize automatic analysis of data to automatically determine whether the product is qualified / unqualified, effectively shorten the test cycle, reduce the manual tedious recording and analysis of data, and improve the validity and accuracy of the data. By generating a multi-channel electrolytic cell performance comparison curve, the quality of the electrolytic cells produced in batches can be seen from an overall perspective, and some factors that lead to unqualified products can also be found. Through comparative analysis, the product improvement direction can be found in a targeted manner, thereby further improving the quality of the product and the production qualification rate.

[0056] like Figure 2 The following table 1 is a test report of the electrolytic cell taking channel 1 as an example.

[0057] Table 1

[0058]

[0059] As can be seen from Table 1, the basic performance and process performance of the electrolytic cell in channel 1 are both qualified, there is no abnormal or pending abnormal data, and the product can be judged to be of first quality.

[0060] The following is an example of the specific process of data sampling in the control system:

[0061] (1) Install multiple electrolyzers that need to undergo steady-state performance tests on different test channels, set the water inlet temperature of the tested electrolyzers (for example, 60°C ± 2°C), rated input current (set according to the design parameters of different electrolyzers), and rated hydrogen output pressure (set according to the design parameters of different electrolyzers), and start the steady-state performance test of multiple channels with one button.

[0062] (2) After the test platform starts running and hydrogen production reaches a steady state (for example, 15 minutes), the control system of the multi-channel automatic test electrolyzer test platform starts sampling. The single test duration is not less than 8 hours, and the total test time is not less than 24 hours. During the test, data are collected at fixed time intervals (at least 1 hour).

[0063] (3) The data collected by each independent test channel include basic condition data and process performance data. Basic condition data include: electrolyzer water inlet temperature, electrolyzer water inlet pressure, electrolyzer water inlet flow rate, electrolyzer water inlet conductivity, electrolyzer hydrogen outlet pressure; process performance data include: output hydrogen flow rate, cell voltage 1…n, average cell voltage, cell voltage deviation, electrolyzer current, electrolyzer total voltage, oxygen content in hydrogen, hydrogen content in oxygen, etc.

[0064] The process performance data that can be directly detected and obtained include: output hydrogen flow, cell voltage 1…n, electrolyzer cell current, oxygen content in hydrogen, hydrogen content in oxygen; the process performance data that need to be further processed by the data processing module include: average cell voltage (average cell voltage = total cell voltage / number of cells), cell voltage deviation (statistically the cell voltage range), electrolyzer DC unit energy consumption W d ( Where W d The DC unit energy consumption value is kW·h / Nm 3 , P is the electrolytic cell input power kW, calculated by the average value of the cell voltage and cell current sampled during steady-state operation).

[0065] Table 2 below sets the fixed value range for the first reference interval of basic performance:

[0066] Table 2

[0067] Test content Eligibility criteria Electrolyzer inlet water temperature 60℃±2℃ Electrolyzer water inlet pressure 0.5bar~1bar Electrolyzer water flow 150L / H±5L / H Conductivity of electrolytic cell water <1μS / cm Hydrogen pressure of electrolyzer 3Mpa±0.2Mpa

[0068] If the first real-time data is not within the above-mentioned first reference interval, it may be caused by external factors or quality problems of the electrolytic cell itself, which requires manual analysis of the specific situation. Therefore, the evaluation method of this application is set to enter the manual inspection procedure after the product is judged to be unqualified.

[0069] (4) If the first real-time data is within the first reference interval, the system automatically determines whether the electrolytic cell is qualified or unqualified based on the process performance data. The following Table 3 shows the fixed value setting range of the second reference interval of the process performance data:

[0070] Table 3

[0071]

[0072] The control system automatically determines whether the tested electrolytic cell is qualified or unqualified through the acquired first real-time data and second real-time data of the electrolytic cell, and outputs the determination result in a report.

[0073] (5) The control system automatically generates a multi-channel electrolytic cell performance comparison curve: with time as the X-axis and the same analysis data as the Y-axis, multiple test channels generate a comparison curve. For example: the average cell voltage data curve comparison of multiple test channels (such as Figure 2 ). For another example, the volt-ampere characteristic curves of multiple electrolytic cells can be automatically generated to evaluate the performance of the electrolytic cells from the overall performance. By comparing the consistency of multiple performance curves of different analysis data and combining the qualified rate of the product, the quality of the electrolytic cells produced in batches can be seen from an overall perspective, and some factors that lead to product failure can also be found.

[0074] In summary, the present application provides an electrolytic cell performance test evaluation method and control system, which determines whether the performance of the electrolytic cell is qualified or pending abnormality based on the comparison of the relevant test data of the basic performance and process performance with the corresponding reference interval. The evaluation method is simple and reliable, with a short test cycle and high accuracy, and the control system can realize automatic test data, automatic analysis of data, and then automatically determine whether the product is qualified / unqualified, effectively shortening the test cycle of the electrolytic cell, improving test efficiency and test accuracy, reducing the manual tedious recording and analysis of data, and improving the effectiveness and accuracy of test data.
