Description

Technical Field

[0001] This application relates to the field of fuel cell technology, and in particular to a temperature-controlled air-cooled fuel cell. Background Technology

[0002] A fuel cell is a chemical device that directly converts the chemical energy of fuel into electrical energy; also known as an electrochemical generator, it is the fourth type of power generation technology after hydropower, thermal power generation, and nuclear power generation. Because fuel cells convert the Gibbs free energy portion of the fuel's chemical energy into electrical energy through an electrochemical reaction, they are not limited by the Carnot cycle effect, resulting in high efficiency. Furthermore, fuel cells use fuel and oxygen as feedstock and have no mechanical transmission components, thus emitting very few harmful gases and having a long service life. Therefore, from the perspective of energy conservation and environmental protection, fuel cells are the most promising power generation technology.

[0003] Existing air-cooled fuel cells have the following problems:

[0004] 1. Insufficient heat dissipation efficiency: The heat dissipation load is large when operating at high power, which can easily lead to overheating failure; it is difficult to start up in low-temperature environments, which affects performance; 2. Single control strategy: Traditional methods rely on fixed temperature heat dissipation and do not combine power to dynamically adjust the air volume, which can easily lead to insufficient oxygen supply or excessive energy consumption. Utility Model Content

[0005] This application provides a temperature-controlled air-cooled fuel cell to solve the problems of insufficient heat dissipation efficiency and lack of dynamic adjustment of air volume in conjunction with power, which can easily lead to insufficient oxygen supply or excessive energy consumption.

[0006] This application provides a temperature-controlled air-cooled fuel cell, including a fuel cell body. A servo motor is fixedly installed in the middle of the top surface of the fuel cell body. A cooling fan is fixedly installed at the output end of the servo motor. An air supply channel is fixedly installed at the positive end of the fuel cell body. A cold channel is connected to one side of the surface of the air supply channel. Two sets of heating elements are fixedly installed inside the cold channel. A power line is electrically connected to the output end of the fuel cell body. A current sensor is fixedly installed on the surface of the power line. An exhaust valve is fixedly installed on one side of the surface of the fuel cell body. A temperature sensor is fixedly installed on the surface of the exhaust valve.

[0007] Preferably, a PLC controller is electrically connected to one side of the temperature sensor, and a servo motor is electrically connected to one side of the PLC controller. The PLC controller is fixedly installed on the top surface of the fuel cell body and is used to control the power of the servo motor.

[0008] Preferably, a temperature and humidity sensor is fixedly installed on one side of the top surface of the air supply channel, and one side of the current sensor is electrically connected to the PLC controller. The current sensor is used to sense the output current of the fuel cell.

[0009] Preferably, a PID temperature controller is electrically connected to one side of the heating element. The PID temperature controller is fixedly installed on the surface of the fuel cell body near the air supply channel. The PID temperature controller is used to control the heating temperature of the heating element.

[0010] Preferably, a solenoid valve is electrically connected to one side of the temperature and humidity sensor. The solenoid valve is fixedly installed on the surface of the air supply channel and is used to control the opening and closing of the air supply channel and the cold channel.

[0011] Preferably, a negative electrode inlet pipe is fixedly installed on the side of the fuel cell body away from the air supply channel, and the cold channel is connected to the interior of the fuel cell body for circulating cold air.

[0012] Preferably, support columns are fixedly provided around the bottom surface of the cooling fan, and the bottom of the support columns is fixedly provided on the top surface of the fuel cell body. The support columns are used to support the cooling fan.

[0013] Beneficial effects:

[0014] Considering the insufficient heat dissipation efficiency and the lack of dynamic airflow adjustment combined with power, problems such as insufficient oxygen supply or excessive energy consumption may easily occur. Temperature sensors are used to collect the temperature at the output end of the fuel cell stack, and current sensors are used to collect the output current data of the fuel cell body. Then, the PLC controller controls the operating power of the servo motor and adjusts the heat dissipation efficiency of the cooling fan, making the temperature of the fuel cell body more stable and improving the efficiency of the fuel cell body. Dynamic airflow adjustment also reduces ineffective heat dissipation and lowers the energy consumption of the cooling fan.

[0015] Temperature and humidity sensors on the air supply channel collect the temperature and humidity data of the intake air. When the intake air temperature is low, the solenoid valve controls the opening of the cold flow channel, the heating element preheats the air to increase the intake air temperature, and the PID temperature controller controls the heating temperature of the heating element, which is convenient for starting in low temperature environments. Moreover, the cold flow channel and the air supply channel are separated from each other, and the air volume can be adjusted independently to balance the temperature and humidity.
