[0033] Auxiliary heating device 3 includes heater 10 and auxiliary heating fan 11. Auxiliary heating device 3 is installed in the system cavity 8 and is connected to system control module 13 to provide additional heating function to ensure that the system can start and work normally in low temperature environment.
[0034] The activation device 4 includes a DC-DC module 12, a system control module 13, and a relay 14. The air-cooled fuel cell 9 is connected to the solenoid valve 6 to achieve efficient activation of hydrogen and improve the performance of the air-cooled fuel cell.
[0035] The relay battery 5 is installed in the system cavity 8 and connected to the air-cooled fuel cell 9 to serve as an energy buffer and improve the system's response speed and stability.
[0036] Solenoid valve 6 is installed on air pipe 7 and opens at regular intervals to ensure the normal operation of air-cooled fuel cell 9;
[0037] Gas pipe 7 is used to connect solenoid valve 6 and air-cooled fuel cell 9 to form a channel for hydrogen flow, ensuring stable power generation of air-cooled fuel cell 9.
[0038] The air-cooled fuel cell 9 is installed in the system cavity 8 and connected to the intake system and exhaust system 2. It efficiently converts hydrogen energy into electrical energy and maintains a suitable operating temperature through air cooling.
[0039] Heater 10 is connected to system control module 13 via wires. Auxiliary heating fan 11 is provided on one side of heater 10 to heat up quickly, shorten system preheating time and improve overall efficiency.
[0040] The air-cooled fuel cell system includes an air-cooled fuel cell 9 and a control system. The integrated design facilitates management and maintenance and improves system reliability.
[0041] In this invention, preferably, the filtration system 1 is located at the front end of the intake system and includes a multi-layer filter and its adsorption membrane. A multi-layer adsorption structure is provided between the outer filter membrane and the inner adsorption layer of the filtration system 1. The control system includes a DC-DC module 12, a system control module 13, and a relay 14. The system control module 13 is connected to the auxiliary heating device 3, the activation device 4, the active pressurization device 15, and the exhaust damper 16. The relay 14 is installed between the system control module 13 and the solenoid valve 6. The DC-DC module 12 is installed near the system control module 13 and connected to it via wires. The system cavity 8 is connected to the filtration system 1 and the exhaust damper 16 via a duct 17, forming a closed gas circulation system. The system control module 13 is connected to each component via wires and includes the auxiliary heating device 3, the active pressurization device 15, the exhaust damper 16, the activation device 4, and the DC-DC module 12. This enhances the filtration effect, prevents impurities from entering the air-cooled fuel cell, and improves system durability; centralized control enables coordinated operation of each component and optimizes system performance.
[0042] The working principle and usage process of this utility model are as follows: When in use, air first enters the system through the filtration system 1. The outer filter membrane of the filtration system 1 performs high-efficiency filtration of PM2.5 with a filtration efficiency of more than 90%. At the same time, the built-in multi-layer adsorption layer, including carbonaceous adsorbent and organic polymer adsorbent, can effectively adsorb harmful substances such as SO2, NOx, NH3, H2S, and VOCs in the air, ensuring that the gas entering the inner cavity 8 of the system is pure and avoiding damage to the air-cooled fuel cell 9.
[0043] In low-temperature environments, the system control module 13 detects the temperature of the system cavity 8 through a temperature sensor. When the temperature is lower than the set value, the system control module 13 activates the auxiliary heating device 3, the heater 10 starts working, and the auxiliary heating fan 11 accelerates heat transfer, quickly raising the temperature of the system cavity 8 to the operating temperature of the air-cooled fuel cell 9. At the same time, it controls the opening of the exhaust damper 16 to reduce heat loss and ensure that the air-cooled fuel cell 9 can start up quickly.
[0044] In high-altitude areas, due to the low oxygen concentration, the system control module 13 controls the active booster device 15 to work, increasing the pressure in the system cavity 8, and at the same time adjusting the opening of the exhaust damper 16 to increase the contact between oxygen and the membrane electrode of the air-cooled fuel cell 9, thereby improving the power reduction problem caused by insufficient oxygen concentration and ensuring the performance of the air-cooled fuel cell 9 in high-altitude environments.
[0045] During the use of the air-cooled fuel cell 9, the activation device 4 will work as needed. The system control module 13 controls the relay 14 to open the solenoid valve 6 to realize the linkage between hydrogen inlet and hydrogen outlet. After hydrogen outlet, during the stable period, the system control module 13 controls the positive and negative terminals of the DC-DC module 12 to short-circuit, so that the current of the air-cooled fuel cell 9 increases instantaneously, the temperature rises sharply, the oxide layer on the membrane electrode detaches, the membrane electrode performance is restored, and the service life of the air-cooled fuel cell 9 is extended.
[0046] The entire system is connected to each component through the air pipe 7 to ensure smooth gas flow. At the same time, the relay battery 5 provides additional power support to the system to ensure stable operation. The exhaust damper 16 and the air duct 17 work together to discharge the exhaust gas out of the system, completing the entire usage process.
[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
