Stable pressure control can improve the lifespan, efficiency, and stability of proton exchange membrane fuel cell system (PEMFCs). We successfully implemented a feedforward-based proportion-integral controller (FPIC) to anode 100 kW system. The bench experimental results demonstrate that stack achieves maximum efficiency 62.3 %, while power generation achieve 53.5 %. Under steady-state dynamic conditions, strategy tracking accuracy 98.93 % 94.47 respectively. To address large overshoot phenomenon slow response speed FPIC when controlling pressure, we further design second order active disturbance rejection (SOADRC). simulation show SOADRC exhibits higher lower than FPIC. Moreover, it demonstrates 51.3 increase in an 80.7 improvement under conditions compared evaluation metrics for error integral criterion (eISE = 0.023, eITSE 2.58, eIAE 0.35, eIEAE 36.76) are FPIC, which provides more precise enhances PEMFCs.
