Referring to fig. 2, in a first embodiment, the testing method of the fuel cell is applied to a testing terminal, and includes the steps of:
step S10, when receiving the testing environment parameter sent by the user end, adjusting the testing environment corresponding to the fuel cell according to the testing environment parameter,
the testing environment parameters comprise at least one of a temperature rising curve, a temperature lowering curve, an air inlet temperature point, an air cut-off temperature point, a gas type, an air inlet flow rate, an input current of an electronic load, an input voltage, an input power, a total voltage of the battery and a partial voltage of the battery;
in this embodiment, the testing end of the fuel cell is connected to the user end, so as to realize data interaction between the testing end and the user end. And when receiving the testing environment parameters sent by the user side, the testing end adjusts the testing environment corresponding to the fuel cell according to the received environment parameters, wherein the testing environment can comprise at least one of the environment temperature, the environment humidity, the type and the flow of gas introduced into the fuel cell, and the power, the current and the voltage of an electronic load communicated with the fuel cell.

Optionally, after acquiring the testing environment parameters, the user side generates first check codes corresponding to the testing environment parameters, and sends the first check codes to the testing side, where the first check codes corresponding to the testing environment parameters may be generated in a hash algorithm or the like. After receiving the testing environment parameters and the first check codes sent by the user side, the testing end generates second check codes according to the received testing environment parameters, wherein the generation mode of the second check codes is the same as that of the first check codes. And the testing end compares the second check code with the received first check code, if the comparison is consistent, the testing end correctly receives the environment testing parameters sent by the user end, the transmission of the testing environment parameters is normal, and the step of adjusting the testing environment corresponding to the fuel cell according to the testing environment parameters is executed. If the comparison is not consistent, the data transmission is abnormal, the test end can maintain the current test environment and feed back prompt information of failed verification to the user end to prompt the user that the data transmission is abnormal.
Optionally, after the testing environment corresponding to the fuel cell is adjusted according to the testing environment parameters, detecting the environment parameters corresponding to the adjusted testing environment, comparing the environment parameters corresponding to the adjusted testing environment with the testing environment parameters sent to the testing end by the user end, if the comparison is consistent, indicating that the testing end normally controls the testing environment, and continuing to test the fuel cell, and if the comparison is inconsistent, indicating that the testing end abnormally controls the testing environment, and sending a prompt message indicating that the testing environment is abnormal to the user end to prompt the user that the testing end abnormally controls.
Step S20, obtaining the corresponding operating parameters of the fuel cell;
in this embodiment, the test end makes the fuel cell enter the test state by adjusting the test environment corresponding to the fuel cell, and at the same time, the operation parameter corresponding to the fuel cell can be detected, and the operation parameter is the test result. The operation parameters can comprise at least one of output voltage, output current, output power, exhaust flow and exhaust temperature of the fuel cell, and the operation state of the fuel cell can be judged according to the operation parameters, so that the aim of testing the fuel cell is fulfilled.
Step S30, feeding back the operation parameters to the user side.
In this embodiment, after obtaining the operating parameters of the fuel cell, the testing end feeds the operating parameters back to the user end, so that the user end outputs the operating parameters of the fuel cell. It should be noted that the test environment of the fuel cell is continuously adjusted according to the test environment parameters, and since the test environment is continuously changed and the operation parameters of the fuel cell are also continuously changed, the steps of acquiring the operation parameters of the fuel cell and feeding the acquired operation parameters back to the user side by the test end can be performed in real time, so that the operation parameters of the fuel cell are fed back to the user in real time, and the real-time monitoring of the fuel cell test by the user is realized.
In the technical scheme disclosed in the embodiment, the testing environment parameters are sent to the testing end through the user end, so that the testing end adjusts the testing environment of the fuel cell according to the received testing environment parameters, the operating parameters of the fuel cell in the testing environment are obtained, the user end remotely controls the testing end, the remote testing of the fuel cell is realized, the condition that the user needs to be in the vicinity of the electric furnace of the testing end for a long time is avoided, and the testing of the fuel cell is more convenient and safer.
In the second embodiment, as shown in fig. 3, on the basis of the embodiment shown in fig. 2, after step S20, the method further includes:
step S01, determining the operation state of the fuel cell according to the operation parameters corresponding to the fuel cell;
in the present embodiment, the operating state of the fuel cell may include a normal state and an abnormal state, and may also include a current abnormal state, a voltage abnormal state, an exhaust gas temperature abnormal state, and the like. After the operation parameters corresponding to the fuel cell are acquired, the operation state of the fuel cell is determined according to the operation parameters, for example, the operation parameters may be compared with a preset range, and when the operation parameters exceed the preset range, it is determined that the fuel cell is in an abnormal state, for example, when the output current of the fuel cell exceeds a maximum current threshold, it is determined that the fuel cell is in an abnormal state or a current abnormal state, and when the exhaust temperature of the fuel cell exceeds a maximum exhaust temperature, it is determined that the fuel cell is in an abnormal state or an exhaust temperature abnormal state.
Step S02, when the operating state of the fuel cell is abnormal, performing the following operations:
step S03, sending the failure prompt information to the user terminal, and when receiving the failure processing information fed back by the user terminal, performing failure processing operation according to the failure processing information,
and step S04, and/or determining the fault type of the fuel cell according to the operation parameters, and executing fault processing operation corresponding to the fault type.
In this embodiment, when the operating state of the fuel cell is detected to be abnormal, a fault is detected in the current test of the fuel cell, and a fault prompt message can be sent to the user terminal. And when the user side receives the fault prompt information, outputting the fault prompt information to prompt the user that the test of the fuel cell is abnormal.
The user can feed back the fault processing information to the testing end through the user end, so that the testing end carries out fault processing operation according to the received fault processing information. For example, a user may adjust the test environment parameters, and send the adjusted test environment parameters to the test end as the fault processing information, so that the test end changes the test environment corresponding to the fuel cell according to the fault processing information, that is, the test fault of the fuel cell is processed through the change of the test environment.
Optionally, when the abnormal operating state of the fuel cell is detected, the testing end may also determine the fault type of the fuel cell according to the abnormal operating parameter. For example, when the output voltage of the fuel cell is low and the exhaust temperature is high, it indicates that the fuel gas introduced into the fuel cell leaks, and when the voltage of the fuel cell suddenly returns to zero, it indicates that the circuit at the test end is short-circuited or open-circuited. After the fault type of the fuel cell is determined, the test end executes fault processing operation corresponding to the fault type, for example, when fuel gas leaks, the test end is controlled to stop in an emergency, when a circuit of the test end is short-circuited or broken, the test on the fuel cell is stopped, the ambient temperature corresponding to the fuel cell is gradually reduced to the room temperature, and the fault is waited to be manually checked.
Optionally, after detecting that the operating state of the fuel cell is abnormal and sending the fault prompting message to the user terminal, if the preset time length still does not receive the fault processing message fed back by the user terminal, the testing terminal may determine the fault type of the fuel cell according to the operating parameter and execute the fault processing operation corresponding to the fault type.
In the technical scheme disclosed in this embodiment, the operating state of the fuel cell is determined according to the operating parameters corresponding to the fuel cell, and corresponding fault handling operation is performed when the state is abnormal, so that the purpose of handling the test fault of the fuel cell when a user remotely tests the fuel cell is achieved, and the loss of the test fault of the fuel cell to the fuel cell is reduced.
In the third embodiment, as shown in fig. 4, on the basis of the embodiment shown in any one of fig. 2 to 3, step S10 includes:
step S11, adjusting the corresponding environment temperature of the fuel cell according to the temperature rising curve;
in this embodiment, when the testing end adjusts the testing environment corresponding to the fuel cell according to the received testing environment parameters, the testing end may adjust the environmental temperature of the fuel cell according to the temperature-rising curve. The regulation of the ambient temperature can be achieved by means of a temperature controller. The target temperature of the temperature rise curve represents the reaction temperature of the fuel gas in the fuel cell, and the target temperature is different depending on the type of the fuel cell, and generally, the target temperature is in the range of 500 ℃ to 900 ℃.
Optionally, the temperature-raising curve includes a plurality of different temperature-raising stages, for example, when the target temperature of the temperature-raising curve is 800 ℃, the ambient temperature corresponding to the fuel cell may be raised to 300 ℃, the ambient temperature may be maintained at 300 ℃ for a first preset time period, the ambient temperature corresponding to the fuel cell may be raised to 500 ℃, the ambient temperature may be maintained at 300 ℃ for a second preset time period, and the ambient temperature corresponding to the fuel cell may be raised to 800 ℃, so as to complete the temperature-raising process.
Optionally, in the temperature reduction phase of the ambient temperature, similar to the temperature increase phase, the ambient temperature corresponding to the fuel cell is adjusted according to the temperature reduction curve.
Step S12, when the environment temperature reaches the air inlet temperature point, introducing air according to the air inlet flow rate and the air type;
step S13, stopping the gas introduction when the environment temperature reaches the gas cut-off temperature point;
in this embodiment, in the process of adjusting the ambient temperature of the fuel cell according to the temperature-raising curve and the temperature-lowering curve, the ambient temperature reaches the air-intake temperature points corresponding to different fuel cells, and gas can be introduced according to the gas types and the air-intake flow rates corresponding to the ambient temperatures corresponding to the air-intake temperature points, where the gas types can include fuel gas, carrier gas, and the like, and according to the different types of the fuel cells, the fuel gas can include hydrogen, natural gas, liquefied gas, methane, ethanol, methanol, oxygen, air, and the like, and the carrier gas can include nitrogen, argon, and other inert gases. For example, when the ambient temperature corresponding to the fuel cell is increased to 300 ℃, continuously introducing nitrogen gas with a first preset flow into the fuel cell to isolate the fuel cell from oxygen in the air, thereby preventing the fuel cell from being oxidized in a high-temperature environment, when the ambient temperature corresponding to the fuel cell is increased to 500 ℃, adjusting the introduced nitrogen gas flow from the first preset flow to a second preset flow, continuously introducing hydrogen gas with a third preset flow, activating the cell in a manner of introducing hydrogen gas, when the ambient temperature corresponding to the fuel cell is increased to 800 ℃, adjusting the introduced nitrogen gas flow from the second preset flow to a fourth preset flow, and adjusting the introduced hydrogen gas flow from the third preset flow to a fifth preset flow, wherein, when the ambient temperature corresponding to the fuel cell is increased to 800 ℃, the hydrogen gas participates in chemical reaction and generates electric energy, the nitrogen gas is used as carrier gas, providing flow power for the hydrogen. The process of introducing gas into the fuel cell is continued, and if the introduction of gas is stopped in a high-temperature environment, the cell may be damaged.
