Application study of the power control system for air-cooled proton exchange membrane fuel cell based on fuzzy adaptive with heuristic adaptive period strategy

Abstract

Abstract As a zero-emission, non-polluting power generation device, hydrogen fuel cells are of great interest to the global industry with the advantages of high-power generation efficiency, wide source, and wide application scenarios. Influenced by various factors, it leads to a complex fuel cell control system and unstable output characteristics, which is one of the difficulties in the current technology development. In this section, an embedded power control system according to an STM32 microcontroller is developed to improve the steady-state characteristics of cathode open air-cooled fuel cell (PEMFC), and a fuzzy adaptive PID control algorithm according to the heuristic adaptive strategy of time interval is proposed. The control system achieves real-time detection of operating status. It maintains the stable output of cathode open air-cooled PEMFC by predicting vehicle speed in real-time to precisely control the hydrogen supply and external additional fans to control the operating temperature by the control strategy.
