Development of a Hybrid System Model for Enhanced Lifespan, Energy Efficiency, and Power Quality in Fuel Cells
Abstract
Fuel cells serve as environmentally friendly alternatives to fossil fuels by providing clean energy.Integrating a fuel cell with an energy storage system, such as a battery, results in cost savings and performance improvements.The battery functions as an energy storage source, enabling the regulation and maintenance of fuel cell power at acceptable levels.Introducing an innovative and optimal power management method for hybrid electric energy supply systems can significantly contribute to the advancement of renewable resources by reducing costs, enhancing energy efficiency, increasing system reliability, and improving fuel cell lifespan.In this study, a membrane exchange fuel cell model, combined with a battery, is presented using MATLAB.The results demonstrate an increase in fuel cell life, energy efficiency, and output power quality.The state of charge (SOC) of the battery fluctuates between 52% and 34%, while the output power of the proton exchange membrane fuel cell (PEMFC) ranges between 30 and 20 watts.It is worth noting that, during the 1,200-second power supply process using the proposed strategy, only six PEMFC working points have changed.
