DESINE OF AN EXPERIMANTAL MEASURMENT AND CONTROL SYSTEMS FOR CUSTOM HYDROGEN FUELCELL

Abstract

This project presents the design and development of an experimental measurement and control system for a custom hydrogen Proton Exchange Membrane (PEM) fuel cell, aimed at improving efficiency, safety, and performance monitoring. The system integrates various sensors and embedded control techniques to continuously monitor key parameters such as temperature, voltage, current, hydrogen flow rate, and gas concentration. A microcontroller-based platform, specifically the Raspberry Pi Pico, is utilized to process realtime data and execute control actions. The proposed system replaces traditional manual monitoring methods with an automated solution, enabling faster response, reduced human error, and improved operational reliability. The incorporation of gas sensors such as MQ7 and MQ135 ensures detection of hazardous gases, enhancing system safety. Additionally, the use of IoT concepts and edge computing allows efficient data processing and potential cloud integration for remote monitoring. The system includes a user interface through an OLED display for real-time visualization of parameters. Power supply circuits, voltage regulators, and communication modules are designed to ensure stable and efficient system operation. Experimental results demonstrate improved control accuracy and system responsiveness compared to conventional methods. This project highlights the potential of embedded systems in advancing hydrogen fuel cell technology and provides a scalable framework for future research and industrial applications in clean energy systems.
