One of the dominant design parameters for high pressure PEMFC system is the operating pressure. High pressure proton exchange membrane fuel cell (PEMFC) engines offer clean and efficient energy production and are advantaged of high stack power density, quick system response, and easy humidification. Simulations and extensive experiments are conducted with the xPC Target and show that the proposed controller can not only achieve good dynamic and static performance but also have strong robustness against parameters' disturbance and external disturbance. The identified parameters are used in designing active disturbance rejection controller (ADRC). The modeling, parameters identification, and nonlinear controller design of a BPV system are considered. This paper analyses a regulated backpressure valve (BPV) for the cathode outlet flow in a high pressure PEMFC engine, which can achieve precisely pressure control. The reactant pressure is crucial to the efficiency and lifespan of a high pressure PEMFC engine.
