The power management of a hybrid system composed of a fuel cell, a battery and a DC/DC power converter is developed. A decoupled control strategy is proposed, aimed at balancing the power flow between the stack and the battery and avoiding electrochemical damage due to low oxygen concentration in the fuel cell cathode. The controller is composed of two components. The first controller regulates the compressor, and as a consequence the oxygen supplied to the cathode, via a classic Proportional-Integral controller. The second controller optimally manages the current demanded by the fuel cell and battery via a linear-quadratic control strategy acting on the converter. An Extended Kalman Filter is also designed in order to estimate the battery State of Charge. The closed-loop performance was tested in simulation using a 310th-order system model. 1 Oil and Gas Science and Technology 65 ARTICULO Di Domenico, D. 43457 Speltino, C. 43458 Fiengo, G. 43459 171731 171731 0 0 0 0 239550 BAAB BAAB 2026-03-05 200046599 0 200046599 2026-03-05 15:14:08 2026-03-05 ARTICULO
