Therefore, the present invention is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.

[0068] First, as Figure 1 As shown, in one embodiment, the present invention provides a multi-mode tester, which is used to test a target reaction tank system, wherein the target reaction tank system includes a proton exchange membrane hydrogen production tank system, an anion exchange membrane hydrogen production tank system, a carbon dioxide reduction tank system and a hydrogen fuel cell tank system.

[0069] The proton exchange membrane hydrogen production cell system uses electricity to split water into hydrogen and oxygen. Water is oxidized at the anode to produce oxygen, protons, and electrons. The protons travel through the proton exchange membrane to the cathode, where they combine with electrons to produce hydrogen.

[0070] Among them, the anion exchange membrane hydrogen production cell system performs electrolysis through the anion exchange membrane. Water is reduced to generate hydrogen at the cathode, and hydroxide ions move through the membrane to the anode, where they are oxidized to generate oxygen.

[0071] Among them, CO2 reduction cell systems convert CO2 into valuable chemicals or fuels, such as methanol or ethanol, through an electrochemical reaction, typically using a catalyst to promote the reaction.

[0072] The hydrogen fuel cell system converts hydrogen and oxygen into electricity and water through an electrochemical reaction. Hydrogen is oxidized at the anode to produce protons and electrons. The protons move through the electrolyte membrane to the cathode, where they combine with oxygen and electrons to form water.

[0073] like Figure 2As shown, the multi-mode tester includes a power supply module, a control module, a power module, a drive module, an acquisition module, an analog output module and a switch module;

[0074] The control module is electrically connected to the power module, the drive module, the acquisition module and the analog output module respectively.

[0075] Among them, the control module is used for overall control, including power supply control and acquisition control.

[0076] The power supply module is electrically connected to the control module, the power module, the drive module, the acquisition module, the analog output module and the switch module respectively.

[0077] Among them, Figure 2 In order to make the figure more concise, the connection relationship between the power module and the control module, power module, drive module, acquisition module, analog output module and switch module is not shown. It is understandable that as long as it is an active module, it can be powered by the power module.

[0078] Among them, the power module can output different power supply voltages according to the power supply requirements of each module, such as 220V, 24V, 12V, 5V and 3.3V.

[0079] The power module is also used to electrically connect to the first electrical device in the target reaction tank system to control the power supply to the first electrical device; the first electrical device includes a motor, a solenoid valve, a water pump, an indicator light and / or a buzzer.

[0080] The power module may be connected in series between the power module and the first electrical device. When the power module is turned on under the control of the control module, the first electrical device is powered.

[0081] The driving module is also used to electrically connect to a second electrical device in the target reaction tank system through the switch module, and to control the power supply to the second electrical device; the second electrical device includes a heater and / or a humidifier.

[0084] The analog output module is used to implement analog output control, specifically controlling the operation of a device or system by outputting a continuously varying electrical signal. This control method is often used in situations requiring precise adjustment, such as regulating motor speed or controlling valve opening. In this embodiment, the analog output module can output a 4-20mA current control signal.

[0085] The acquisition module is also used to be electrically connected to the acquisition device in the target reaction tank system to perform acquisition control on the acquisition device.

[0086] The acquisition device includes a temperature acquisition device, an analog quantity acquisition device, a pressure acquisition device, a gas flow acquisition device, a humidity acquisition device and / or a liquid mass flow acquisition device.

[0087] The control module is also used to be electrically connected to an electrochemical workstation for performing data processing on the target reaction tank system and a multi-channel digital power supply for digitally powering the target reaction tank system.

[0088] Among them, the electrochemical workstation is mainly used for data processing of hydrogen fuel cell tank systems, including evaluating and optimizing the performance of fuel cell catalysts (including activity, stability and durability), researchers developing and testing new electrode materials and electrolyte materials, simulating the working conditions of fuel cells and testing their performance and efficiency, and analyzing the failure mechanism of fuel cells through electrochemical impedance spectroscopy and other technologies.

[0089] The multi-channel digital power supply primarily provides the power required for electrolysis in the hydrogen production cell system, which relies on the power provided by the power supply to decompose water molecules into hydrogen and oxygen. First, the digital power supply optimizes power conversion efficiency, reduces energy loss, and improves hydrogen production efficiency. Second, the digital power supply can quickly respond to load changes and adapt to fluctuating inputs from renewable energy sources (such as solar and wind power), ensuring stable system operation. Finally, the digital power supply provides precise voltage and current control, ensuring the stability and safety of the electrolysis process.

[0090] The above-mentioned multi-mode tester is respectively provided with a power supply module, a control module, a power module, a drive module, an acquisition module, an analog output module and a switch module. The power supply module, the control module and the power module can be used to control the power supply of the first electrical device in the target reaction tank system; the power supply module, the control module, the drive module and the switch module can be used to control the power supply of the second electrical device in the target reaction tank system; the power supply module, the control module and the analog output module can be used to control the power supply of the third electrical device in the target reaction tank system; the power supply module, the control module and the acquisition module can be used to control the acquisition of the acquisition device in the target reaction tank; the present application realizes the power supply control of different electrical devices and the acquisition control of the corresponding acquisition devices, and can be applied to proton exchange membrane hydrogen production tank systems, anion exchange membrane hydrogen production tank systems, carbon dioxide reduction tank systems and hydrogen fuel cell tank systems at the same time. It has rich testing functions and high integration, which ultimately reduces the overall cost of testing.

[0091] like Figure 3 As shown, in one embodiment, the power module includes a 380VAC three-phase power input terminal, a grounding protection contact, a three-phase power control relay, a connection bar (L1, L2, L3, N), an auxiliary power supply, and a solid-state relay group power supply. The control module includes a host computer and a middle computer. The power module includes power card 1 and power card 2. The drive module includes drive card 1 and drive card 2.

[0092] Among them, the proton exchange membrane hydrogen production tank system includes a proton exchange membrane electrolyzer (i.e. Figure 3 The anion exchange membrane hydrogen production system includes an anion exchange membrane electrolyzer (i.e. Figure 3 The AEM electrolyzer (in the example) and corresponding electrical components and collection components. The hydrogen fuel cell system includes the hydrogen fuel cell system and corresponding electrical components and collection components. The carbon dioxide reduction cell system includes the carbon dioxide reduction cell and corresponding electrical components and collection components.

[0093] The central computer, power card 1, power card 2, driver card 1, driver card 2, acquisition card 1, acquisition card 2, and 4-20mA analog output card are integrated on the communication baseboard. The central computer exchanges commands with power card 1, power card 2, driver card 1, and driver card 2 via 485 communication. The central computer also exchanges commands with acquisition card 1, acquisition card 2, and the 4-20mA analog output card via SPI communication. It is important to note that power card 1, power card 2, driver card 1, driver card 2, acquisition card 1, acquisition card 2, and the 4-20mA analog output card each contain corresponding control circuits, such as an MCU, which acts as a slave computer to communicate with the central computer.

[0094] The 380VAC three-phase power input terminal receives 380VAC three-phase power and outputs it to each circuit breaker through the connecting bar. Each circuit breaker can draw power from the connecting bar, for example, 220VAC single-phase power.

[0095] The auxiliary power supply receives 220VAC single-phase power through an auxiliary power circuit breaker and converts it to 24V DC. This 24V DC power is then fed to the communication board and the host computer. The communication board also integrates a corresponding power supply module, which converts the incoming 24V DC power to 12V DC, 5V DC, and 3.3V DC.

[0096] The solid-state relay group power supply receives 220VAC single-phase power through the DC solid-state relay power circuit breaker and converts it to output 24V DC power. The 24V DC power output by the solid-state relay group power supply is output to 8 DC solid-state relays.

[0097] The potentiostat circuit breaker directly outputs the incoming 220VAC single-phase power to the potentiostat. The AC solid-state relay circuit breaker directly outputs the incoming 220VAC single-phase power to eight AC solid-state relays. The digital power supply circuit breaker directly outputs the incoming 220VAC single-phase power to the multi-channel digital power supply.

[0098] The intermediate computer sends corresponding PWM drive signals to the AC solid-state relay and the DC solid-state relay respectively through isolated 485 communication and drive card 1, drive card 2, connecting line 3 and connecting line 4.

[0099] The 8 DC solid-state relays can realize the DC thyristor control of 8 channels and the gas path heating and humidification control of 8 channels in the target reaction tank system according to the connected PWM drive signal and 24V DC power.

[0100] The 8 AC solid-state relays can realize 8-channel AC thyristor control and 8-channel plate heating and humidification control in the target reaction tank system according to the connected PWM drive signal and 220VAC single-phase electricity.

[0101] A corresponding DC solid-state relay fuse can also be set between the DC solid-state relay power supply circuit breaker and the DC solid-state relay power supply, and a corresponding AC solid-state relay fuse can also be set between the AC solid-state relay power supply circuit breaker and the AC solid-state relay to further improve the protection performance.

[0103] The acquisition module includes a temperature acquisition unit and an analog acquisition unit. Figure 3 In the example, acquisition card 1 integrates a temperature acquisition unit and an analog acquisition unit. The output of the temperature sensor corresponding to the temperature acquisition unit and the output of the 4-20mA sensor corresponding to the analog acquisition unit are electrically connected to the central electromechanical unit via connection cable 5, acquisition card 1, and isolated SPI communication. The outputs of the pressure sensor, gas flow sensor, and humidity sensor are electrically connected to the central electromechanical unit via connection cable 6, acquisition card 2, and isolated SPI communication.

[0105] In one embodiment, the temperature sensor comprises an RTC temperature sensor.

[0106] RTC temperature sensors operate based on a thermistor or integrated temperature sensor. A thermistor changes its resistance as temperature changes, and temperature information is obtained by measuring this change in resistance. RTC temperature sensors typically offer high accuracy and stability and operate over a wide temperature range.

[0107] like Figure 3 As shown, in one embodiment, the intermediate computer and the host computer are electrically connected via an isolated 485 communication interface, and the host computer is electrically connected to the electrochemical workstation and the multi-channel digital power supply via Ethernet.

[0108] like Figure 3 As shown, in one embodiment, the multi-mode tester further includes an emergency stop module.

[0109] The emergency stop module is electrically connected to the center position in the control module and is used to output an emergency stop control signal to the control module so that the control module disconnects part or all of the power supply.

[0110] The emergency stop module includes an emergency stop button, which sends a corresponding emergency stop control signal to the central control unit based on its own switch status. The central control unit can stop sending the corresponding drive signal after monitoring relevant data to stop power control and cut off the corresponding power supply signal.

[0112] The source of the MOS transistor Q3 and the source of the MOS transistor Q22 are respectively connected to the 24V DC output of the auxiliary power supply through the diode D19, thereby outputting the power supply VIN+ of electrical components such as the solenoid valve and the motor through the drain of the MOS transistor Q3 and the drain of the MOS transistor Q22.

[0113] The parallel connection of the MOS tube Q3 and the MOS tube Q22 can increase the input current and realize reverse connection protection at the same time, thereby preventing the explosion problem caused by reverse connection.

[0114] like Figure 5 As shown, in one embodiment, the power supply module integrated on the communication baseboard further includes a BUCK circuit mainly composed of a power chip U4 and a diode D3.

[0115] The anode of the diode D3 is connected to the 24V DC power output by the auxiliary power supply, thereby outputting 12V DC power through the cathode of the diode D3 and the power chip U4.

[0116] In other embodiments, it is also possible to change Figure 5 The specifications of the corresponding components in the buck circuit are shown, thereby obtaining a buck circuit that receives 24V DC and outputs 5V DC.

[0117] In other embodiments, it is also possible to change Figure 5 The specifications of the corresponding components in the buck circuit are shown, thereby obtaining a buck circuit that receives 24V DC and outputs 3.3V DC.

[0118] like Figure 6 and Figure 7As shown, in one embodiment, the power module includes a control circuit (such as an MCU), a driver chip U1, and a gain amplifier circuit mainly composed of a MOS transistor Q7.

[0119] The driver chip U1 is used to receive the control signal MCU_DCM1_ON output by the MCU, thereby outputting the drive signal DCM1_ON to the gate of the MOS transistor Q7, thereby driving the MOS transistor Q7 to turn on. The power supply VIN+ can form a path through the terminal J5 and the MOS transistor Q7, so that the electrical device connected to the terminal J5 is powered on.

[0120] It should be noted that the driver chip U1 is also used to access the control signal MCU_DCM2_ON output by the MCU, thereby outputting the drive signal DCM2_ON. The drive signal DCM2_ON is used to drive the MOS tubes in other gain amplifier circuits to turn on.

[0121] like Figure 8 As shown, in one embodiment, the emergency stop module includes a control circuit (such as an MCU) and an emergency stop execution circuit mainly composed of a transistor Q6 and an optocoupler U10.

[0122] Among them, terminal J9 is connected to the external emergency stop button, the E_STOP and GND power supply voltage is 24V, and the driving bias voltage of transistor Q6 is set by resistors R90 and R91. When the external emergency stop button is pressed, transistor Q6 is turned on, optocoupler U10 is turned on, and the trigger signal MCU_ESTOP_DET sent to the MCU is high.

It has rich testing functions and high integration, which ultimately reduces the overall cost of testing.

[0139] like Figure 17 As shown, in one embodiment, the proton exchange membrane hydrogen production tank system includes a proton exchange membrane electrolyzer 104, a cooling water tank 106, a plurality of water pumps (including a first gear pump 105, a second gear pump 110 and a peristaltic pump 115), a pure water tank 114, an ion exchange column 112, a cooling circulation tank 111 and a proton exchange membrane circulation tank 113.

[0140] The cooling water tank 106 is connected to the cooling circulation tank 111 through the first gear pump 105 and is used to continuously reduce the temperature in the cooling circulation tank 111 .

[0141] The pure water tank 114 is connected to the proton exchange membrane circulation tank 113 through a peristaltic pump 115, and the proton exchange membrane circulation tank 113 is also connected to the ion exchange column 112 and the proton exchange membrane electrolyzer 104 respectively through a second gear pump 110, so that the circulating water flows into the proton exchange membrane electrolyzer 104 after being cooled by the cooling circulation tank 111.

[0142] Among them, Figure 17 In the embodiment, the proton exchange membrane hydrogen production tank system further includes a manual back pressure valve 101 , a gas-liquid separation tank 102 , a solenoid valve 103 , a rotor flowmeter 107 , a three-way valve 108 , a manual ball valve 109 and a one-way valve 116 .

[0143] Among them, the system's electrolyzed water source is supplied by a pure water tank 114. The water replenishment function of the proton exchange membrane circulation tank 113 is achieved by starting the peristaltic pump 115 and opening the water replenishment solenoid valve 103. After the second gear pump 110 is started, pure water can flow to the proton exchange membrane electrolyzer 104 through the three-way valve 108. The rotor flowmeter 107 detects the water flow flowing into the proton exchange membrane electrolyzer 104. The proton exchange membrane circulation tank 113 enables the proton exchange membrane electrolyzer 104 to achieve a continuous supply of pure water. The proton exchange membrane circulation tank 113 is equipped with a heating rod, a temperature sensor, and a liquid level sensor. Its purpose is to heat the pure water to a certain temperature to improve the efficiency of the proton exchange membrane electrolyzer 104, so as to meet the efficiency requirement test of the proton exchange membrane electrolyzer 104 at various temperatures. The temperature sensor realizes temperature acquisition and the liquid level sensor realizes water level detection. When the system detects that the water level is lower than the preset minimum through the liquid level sensor, the proton exchange membrane electrolyzer 104 stops loading the DC electrolysis current. Three-way valve 108 connects ion exchange column 112 and cooling circulation tank 111, enabling the system's cooling water to circulate back to cooling water tank 106, thus achieving the circulating electrolysis of the electrolyzed water. The flow rate within the pipeline can be controlled by adjusting the opening of manual ball valve 109. Rotating the handle 90° quickly closes the valve, cutting off the flow of liquid or gas in the pipeline. This function is particularly important during emergency shutdowns or accident handling. The gas-liquid separator 102 is a device used to separate gas from liquid. After the gas-liquid mixture passes through separator 102, a selective membrane or adsorbent separates hydrogen from the other liquids to produce high-purity hydrogen. A liquid level sensor within the separator detects the water level in the tank. When the level reaches a certain value, the drain solenoid valve 103 opens to drain the water. The manual backpressure valve 101 prevents liquid from flowing back into the pipeline. When liquid flows toward one end of the pipeline, the manual backpressure valve 101 opens, allowing liquid to flow through. When liquid flows in the reverse direction, the manual backpressure valve 101 closes, preventing liquid flow.
