The fuel cell controller is the command center of the fuel cell system. It has three main functions, i.e., to start the fuel cell system, to ensure the stable operation of the system, and to shut down the fuel cell system. The fuel cell controller executes the control strategies to direct the anode sub-system, the cathode subsystem, and the thermal management subsystem according to the external load power demand. In the meantime, it monitors the system operation status in real time by using various sensors (e.g., thermocouples, pressure sensors, mass flow meters, humidity sensors, etc) to ensure the stability and safety of the system operation. APT has developed a dedicated controller for fuel cell systems, which has the features of reliability, stability, and precision. It can accurately control the fluid, maintain the stable operation of the fuel cell system, and improve the efficiency and life of the fuel cell system.
APT's fuel cell controller has the following characteristics:
- High-speed operating capability: It uses 32-bit DSP high-speed processor with built-in high-resolution ADC and quick PWM output.
- Precision analog operation design: It can acquire the sensor signals accurately and quickly and can instantly obtain the system operating condition for control strategy operation.
- Remote communication technology: It can remotely collect the fuel cell system parameters for diagnosis.
- Automatically operating the monitoring system: It has system error prediction and smart debugging functions.
- Electromagnetic compatible design: It can avoid electromagnetic wave interference, thus increasing product reliability.
- Isolated Communications interfaces: CAN 2.0, RS485, RS232
