In the existing detection equipment for the electrochemical performance of the fuel cell, because the detection equipment is independent, data detected by the equipment, such as current, voltage and the like, needs to be respectively introduced into a system, which causes the electrochemical performance of the existing fuel cell to be very complicated. In addition, the flow rate of the fuel introduced into the fuel cell may also affect the electrochemical performance of the fuel cell, so that the flow rate of the fuel introduced into the fuel cell needs to be detected during the electrochemical performance test of the fuel cell, which further aggravates the complexity of the electrochemical performance test of the fuel cell.
Based on the problem, the utility model provides a fuel cell test system to overcome the problem that current test equipment exists.
In the embodiment of the present invention, please refer to fig. 1, the fuel cell testing system includes a detecting module 100 and a processing module 200, wherein the processing module 200 is electrically connected to the detecting module 100. Specifically, the detection module 100 includes a flow detection module 110, a temperature detection module 120, a current detection module 130, and a voltage detection module 140. The flow detection module 110 is used for detecting a flow value of fuel introduced into the fuel cell, the temperature detection module 120 is used for detecting an operating temperature value of the fuel cell, and the current detection module 130 and the voltage detection module 140 are respectively used for detecting a current value and a voltage value of the fuel cell. The processing module 200 can obtain the flow value, the temperature value, the current value and the voltage value detected by the detecting module 100. Meanwhile, the processing module 200 may further obtain the power value of the fuel cell by the voltage value and the current value detected by the detecting module 100. After obtaining the power value of the fuel cell, the processing module 200 simultaneously outputs the flow value, the temperature value, the current value, the voltage value and the power value of the fuel cell.
It can be understood that, compared with the existing testing equipment, the fuel cell testing system of the present application can simultaneously detect the flow value, the temperature value, the current value and the voltage value of the fuel cell through the detection module 100. And then the processing module 200 can obtain the power value of the fuel cell according to the detected current value and voltage value, and finally, the flow value, temperature value, current value, voltage value and power value of the fuel cell are output at the same time. In this way, not only the data obtained by testing each module can be correlated, but also the power value of the fuel cell can be calculated in real time by the processing module 200. Therefore, compared with the existing testing equipment, the fuel cell testing system has the advantages of high equipment integration degree, convenience in testing and capability of greatly reducing the workload of testing personnel.
Preferably, in this embodiment, the fuel cell is a gas fuel cell, and hydrogen and oxygen are introduced into an anode and a cathode of the fuel cell, respectively. The hydrogen-oxygen fuel cell has the advantages of environmental protection, easy fuel acquisition, high energy conversion efficiency and the like. It should be noted that in other embodiments of the present application, the anode and the cathode of the fuel cell may be respectively introduced with other gases, such as natural gas and oxygen, petroleum gas and oxygen, etc. . It is understood that in some embodiments of the present application, the fuel of the fuel cell may also be in a liquid state, for example, the anode of the fuel cell may be filled with liquid hydrocarbons such as methanol, ethanol, liquefied natural gas, liquefied petroleum gas, etc.
Referring to fig. 1, the fuel cell testing system of the present embodiment further includes a regulating module 300. The adjustment module 300 includes a flow adjustment module 310, where the flow adjustment module 310 is configured to adjust the flow of fuel to the fuel cell. The electrochemical performance of the fuel cell is affected by the magnitude of the fuel flow within the fuel cell. The flow regulating module 310 regulates the flow of fuel in the fuel cell, so that the electrochemical performance of the fuel cell can be tested under different flow conditions, and richer test data can be obtained.
Specifically, the flow regulating module 310 includes an anode regulating module 311 and a cathode regulating module 312. The anode adjustment module 311 is configured to couple to the anode of the fuel cell to adjust the flow of fuel to the anode of the fuel cell. The cathode adjustment module 312 is configured to couple to the cathode of the fuel cell to adjust the flow of fuel to the cathode of the fuel cell. It is known from the operating principle of the fuel cell that the fuel cell is continuously supplied with fuel at the cathode and the anode during the operation. The anode fuel and the cathode fuel react in a certain proportion in the fuel cell, so that the flow of the anode fuel of the fuel cell can be adjusted by the cooperation of the anode adjusting module 311 and the cathode adjusting module, and the flow of the cathode fuel of the fuel cell can be adjusted at the same time, so that the fuel of the anode and the fuel of the cathode in the fuel cell are kept in an optimal proportion. Of course, since the flow rate adjustment module 310 can adjust the fuel flow rate of the anode and the cathode of the fuel cell respectively, under certain specific test conditions, the tester can also adjust the fuel flow rate of only one pole of the fuel cell, and keep the fuel flow rate of the other pole unchanged, so as to test the electrochemical performance of the fuel cell under the specific test conditions, and increase the test data of the fuel cell.
In addition to the flow regulation module 310, the regulation module 300 further includes a temperature regulation module 320, the temperature regulation module 320 being configured to regulate the operating temperature of the fuel cell. Theoretically, the essence of the operation of a fuel cell is the electrochemical reaction between the anode fuel and the cathode fuel. The nature of the chemical reaction is the process of breaking old molecules into atoms, which recombine into new molecules. Meanwhile, the fuel cell generates electricity due to the exchange of electrons caused by the redox reaction occurring at the cathode and the anode. In this electrochemical reaction, the temperature also directly affects the efficiency of the redox reaction. The temperature changes the reactivity of atoms and affects the speed of bonding between atoms. Chemical reactions are therefore generally affected by temperature. That is, in addition to flow, the electrochemical performance of the fuel cell is also affected by the operating temperature. The inventor of the present application also verifies the conclusion that the temperature affects the electrochemical performance of the fuel cell through practical tests. Therefore, the working temperature of the fuel cell is adjusted by the temperature adjusting module 320, so that the electrochemical performance of the fuel cell can be tested under different temperature adjustments, and richer test data can be obtained.
The fuel cell testing system of the present application further includes a feedback module 400 based on the flow rate adjustment module 310 and the temperature adjustment module 320. The feedback module 400 is electrically connected to the detection module 100 and the adjustment module 300, and is configured to obtain a flow value, a temperature value, a current value, and a voltage value detected by the detection module 100, and control the adjustment module 300 to adjust the flow of fuel introduced into the fuel cell when the temperature value changes, so that the current value and the voltage value of the fuel cell remain unchanged; or when the current value changes, the control and adjustment module 300 adjusts the operating temperature of the fuel cell so that the current value and the voltage value are kept unchanged. That is, the feedback module 400 functions to maintain the power of the fuel cell constant by controlling the adaptive adjustment of the operating temperature or the fuel flow rate of the fuel cell.
It can be understood from the above description that the operating temperature and the fuel flow rate of the fuel cell have an influence on the electrochemical performance of the fuel cell. The purpose of the feedback module 400 is therefore to enable the fuel cell to observe the changes in the operating temperature and the fuel flow rate of the fuel cell while maintaining a certain power, such as peak power, by adjusting between the operating temperature and the fuel flow rate of the fuel cell. In the practical application process of the fuel cell, the situation that the power is required to be kept in a stable output state inevitably exists, so the test of the condition can imitate the practical use situation of the fuel cell as much as possible. Therefore, the functions of the fuel cell testing system are expanded, and the practicability of the testing system is greatly improved.
It should be noted that after a lot of tests, the inventor collates the test data and finds that, when the power of the fuel cell is kept constant, the change of the operating temperature of the fuel cell has a fixed corresponding relationship with the change of the fuel flow rate. That is, when the power is maintained at P, the fuel flow rate corresponding to the operating temperature C1 is Q1, the fuel flow rate corresponding to the operating temperature C2 is Q2, and the fuel flow rate corresponding to the operating temperature Cn is Qn. Therefore, the inventor inputs the corresponding relationship between the operating temperature and the fuel flow rate into the feedback module 400, and when the operating temperature or the fuel flow rate of the fuel cell changes, the feedback module 400 can control the adjusting module 300 to adjust the fuel flow rate or the operating temperature accordingly according to the corresponding relationship. The feedback module 400 can respond quickly and has high timeliness due to the clear corresponding relation. Of course, in other embodiments of the present application, the feedback module 400 may also control the adjusting module 300 to gradually adjust the operating temperature or the fuel flow of the fuel cell, so that the current and the voltage of the fuel cell gradually return to the levels before the operating temperature or the fuel flow changes, thereby keeping the power of the fuel cell unchanged.
on the basis of the above embodiment, the fuel cell further includes a display module 500, and the display module 500 is electrically connected to the processing module 200 for displaying the flow value, the temperature value, the current value, the voltage value, and the power value. It is understood that the tester can observe the variation of each test parameter in real time through the display module 500.
Specifically, referring to fig. 2 to 4, in the present embodiment, the display module 500 displays the time-varying current value, voltage value and power value of the fuel cell at a certain operating temperature and fuel flow rate by means of a line graph. Of course, in other embodiments of the present application, the display module 500 may also display the respective data in the form of a graph and/or a table.
The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structure changes made by the contents of the specification and the drawings under the inventive concept of the present invention, or the direct/indirect application in other related technical fields are included in the patent protection scope of the present invention.
