ABSTRACT This article proposes a temperature control strategy on the basis of active disturbance rejection control (ADRC) algorithm and simultaneously puts forward a kind of strategy of adaptive control of hydrogen gas by means of ampere‐hour integral value and threshold value, so as to effectively control the temperature of battery stack and anode emission of air‐cooled proton exchange membrane fuel cells (PEMFC); the mathematical models of the fuel cell stack and the temperature are established on MATLAB/Simulink. Through simulation, this article compares the ADRC algorithm proposed herein with the traditional PID control method. The results demonstrate the ADRC's superiority: under step load disturbances, the ADRC strategy achieves a 66.7% reduction in settling time and over 34.1% suppression of maximum overshoot, enabling accelerated convergence to stable operation within the system's rated operating range. Meanwhile, an experimental platform for water management of air‐cooled PEMFCs is established to validate the effectiveness of the proposed anode emission strategy, with comparative experiments against conventional periodic emission solutions under dynamic operating conditions. The proposed adaptive strategy in the article reduced hydrogen consumption by 21% relative to conventional timed strategy under identical runtime. The experiment results present that both strategies can avoid water flooding or membrane drying failure and maintain the proper operation of the fuel cell. Furthermore, the ampere‐hour integral threshold method can reduce hydrogen consumption and improve fuel utilization rate.
