[0038] The air inlet pipe 107, the first ball valve 106, the pressure regulating valve 105, the second ball valve 103, the rotor flowmeter 102 and the air pipe joint are connected in sequence through a gas pipeline; the pressure gauge 104 and the rotor flowmeter 102 are arranged on the surface of the shell 101 and can be arranged on the panel assembly.

[0040] Furthermore, there are three air inlet channels, including a hydrogen channel, a nitrogen channel and an air channel. The three air inlet channels of this embodiment are used to circulate hydrogen, nitrogen and oxygen respectively.

[0041] It is particularly noted that a control module is provided in the device for adjusting and controlling the operation of various functional components.

[0042] When performing the demonstration work, first open the first ball valve 106 of the nitrogen channel, adjust the corresponding pressure regulating valve 105 to adjust the intake pressure to a suitable pressure, and the specific pressure value after pressure regulation can be read from the pressure gauge 104, and then open the second ball valve 103 to pass the gas into the fuel cell stack for pre-intake purge. The gas flow rate is adjusted by the knob of the rotor flowmeter 102, and the rotor flowmeter 102 can intuitively see the intake flow rate. After the purge is completed, close the two ball valves of the nitrogen inlet pipe;

[0043] Then open the first ball valve 106 of the hydrogen channel, adjust the corresponding pressure regulating valve 105 to adjust the intake pressure to a suitable pressure, and read the specific pressure value after pressure regulation from the pressure gauge 104, then open the second ball valve 103 to pass the gas into the fuel cell stack for intake electrochemical reaction, and the gas flow rate is adjusted by the knob of the rotor flowmeter 102, and the rotor flowmeter 102 can intuitively show the intake flow rate;

[0044] Finally, open the first ball valve 106 of the air channel, adjust the corresponding pressure regulating valve 105 to adjust the intake pressure to a suitable pressure, and read the specific pressure value after pressure regulation from the pressure gauge 104, and then open the second ball valve 103 to pass the gas into the fuel cell stack for intake electrochemical reaction. The gas flow rate is adjusted by the knob of the rotor flowmeter 102, and the rotor flowmeter 102 can intuitively show the intake flow rate.

[0045] Through the above operation, the required gas can be input into the stack for demonstration, and then the fuel cell assembly 204 is heated according to the set temperature through the heating tube 201, so that the fuel cell assembly 204 can achieve the stack reaction for demonstration. The panel assembly mainly provides operation buttons and a display module for observing process parameters.

[0046] Example 2

[0047] This embodiment is based on the technical solution of Embodiment 1, and mainly further explains each internal execution unit.

[0048] First, rollers are arranged at the bottom of the shell 101 to facilitate movement on a plane. The heating tube 201 and the fuel cell assembly 204 are both arranged inside the shell 101. The shell 101 is preferably made of metal.

[0049] In order to provide better thermal insulation for the fuel cell assembly 204 , the interior of the box may be filled with thermal insulation material 202 .

[0050] On the other hand, see Figure 3 The heating module includes a switching power supply 109, a temperature control instrument 110, a temperature control switch 111, a temperature control interface 112 and a heating line 113 connected in sequence, and the heating line 113 is connected to the heating tube 201; the temperature control instrument 110 is arranged in front of the housing 101 as a display module. The switching power supply 109 and the temperature control switch 111 can also be arranged at the panel assembly for easy operation.

[0051] Furthermore, the number of the heating tube 201 is at least one. When the number is greater than one, a plurality of the heating tubes 201 are connected in series.

[0052] As a preferred solution of this embodiment, a first thermocouple and a second thermocouple are respectively provided at the bottom and the top of the fuel cell.

[0053] Finally, the display module may include two temperature measuring instruments 108, and the temperature measuring instruments 108 are respectively connected to the output end of the first thermocouple and the output end of the second thermocouple. It is particularly noted that in addition to the two temperature measuring instruments 108, a power-on indicator light 115 may also be provided.

[0054] After all the required gases are input into the battery stack for demonstration, the switch power supply 109 of the heating module is turned on, the heating temperature is set through the operation button on the panel assembly, and the heating tube 201 is energized through the temperature control switch 111. At this time, the fuel cell assembly 204 as the battery stack begins to heat up, and the battery stack feeds back its own surrounding temperature to the temperature control instrument 110 through the first thermocouple and the second thermocouple. The temperature control instrument 110 controls the heating circuit to energize according to the feedback value to achieve the purpose of temperature control. The set temperature and the actual temperature can be intuitively displayed on the instrument panel.

[0055] After the above steps, the solid oxide fuel cell in the stack reacts with hydrogen and oxygen at high temperature to release electricity (SOFC). A load can be connected to both ends of the output lead 203 to do work, or a meter can be connected to measure the discharge data for display. The actual temperature measured by the first thermocouple and the second thermocouple can also be displayed by two temperature measuring instruments 108.

[0056] After completing the work, you can also stop the machine by pressing the corresponding button. First, set a lower working temperature of about 400 degrees through the temperature control instrument 110. After the actual temperature drops to the set temperature, turn off the temperature control switch 111 to disconnect the stack heating, then reduce the intake of oxygen and hydrogen, and when the temperature drops to about 200 degrees, turn off the intake of oxygen and hydrogen, and finally turn off the power.

[0057] An emergency button may be provided on the panel assembly, and if an emergency occurs, the emergency stop button 114 may be pressed at any time to cut off power to and shut down the device.

[0058] The entire process of solid oxide fuel cell power generation is quickly and conveniently realized through the above-mentioned devices and control methods.

[0059] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
