Design of a marine hydrogen fuel cell management system based on multi-sensor fusion

As a new generation of clean energy, hydrogen fuel cells have been used in the marine industry, and their safety monitoring is an important measure to ensure the safe operation of ships. The system uses multiple sensors to determine the current operating status through real-time information fusion, and uses pulse width to regulate the flow rate of the inlet valve to achieve safe control of the hydrogen fuel and maximise its output power. The article analyses the composition of the control system, the sensor system and its working principle, and uses an STM32-based microprocessor to design the safety control hardware and give the implementation flow of its software algorithm. The test results show that the system is capable of monitoring the safety of the marine hydrogen fuel cell under operating conditions and can cut off the inlet valve in case of emergency to achieve the safety control function.
