Research on Controlling Gas Flow in Fuel Cells Based on PID Algorithm

With the rapid advancement of technology, improving energy utilization and addressing pollution issues have become urgent tasks. As an emerging field within new energy, fuel cells play a significant role in enhancing energy efficiency and extending service life. The power generation efficiency of fuel cells is primarily related to the stoichiometric ratio of oxygen. Therefore, this article will use the PID control algorithm to regulate the gas flow of the fuel cell, specifically by controlling the numerical value of the oxygen stoichiometric ratio of the fuel cell, which in turn regulates the air flow. This aims to improve energy utilization efficiency, enhance battery power generation efficiency, and extend.
