Dynamic and Precise Temperature Control Unit for PEM Fuel Cell Stack

Fuel cell technology has begun to be applied in the automotive field in recent years, and our country is also vigorously developing this industry. With the development needs of this emerging industry, battery assembly test benches and supporting special equipment also require supporting research and development. At present, there is a relative lack of temperature control systems for supporting fuel cell testing in China, and there is an urgent need to develop a fuel cell testing temperature control unit suitable for fuel cell temperature testing needs.

The main test purpose of the fuel cell test temperature control unit is to test the starting characteristics of the fuel cell under different ambient temperatures and to verify the battery performance at different temperatures. Since the simulation of ambient temperature is generally implemented in an environmental test chamber, the temperature control unit mainly prepares low-temperature circulating coolant. The circulating coolant enters the cooling channels of the motor, controller, proton exchange unit and other components to achieve different parts of the powertrain. Achieve different flow and test temperature requirements, and verify its performance at low temperature start-up and operation at different temperatures.

The fuel cell test temperature control unit adopts a double-stage cascade vapor compression refrigeration cycle. The temperature of the circulating cooling medium can reach minus 60°C, which can meet the battery cold start test requirements in all regions on the earth. The controller based on the PID algorithm controls the refrigerant flow. , to achieve high-precision temperature control requirements for different channels. It has high-pressure, low-pressure, oil shortage, overload, over-temperature and other safety protections to protect the oil return of the compressor and the safe operation of the equipment.

The fuel cell test temperature control unit realizes the requirements for different flow rates and test temperatures in different parts of the powertrain. It can verify its performance at low temperature start-up and operation at different temperatures. It can also be used in similar lithium battery and motor testing industries.
