“…One of the reasons could be that it would be easier to study and define operating conditions for aeronautic applications after broadening the understanding of environmental effects on PEMFC performance and lifetime. Research on operating conditions is predominantly limited to stationary and terrestrial conditions [31][32][33][34][35][36][37][38][39]. Information obtained on effect of aeronautic conditions on PEMFC will assist in defining the optimum operating conditions.…”

Proton exchange membrane fuel cells (PEMFC) not only offer more efficient electrical energy conversion, relative to on-ground/backup turbines but generate by-products useful in aircraft such as heat for ice prevention, deoxygenated air for fire retardation and drinkable water for use on-board. Consequently, several projects (e.g. DLR-H2 Antares and RAPID2000) have successfully tested PEMFC-powered auxiliary unit (APU) for manned/unmanned aircraft. Despite the progress from flying PEMFC-powered small aircraft with 20 kW power output as high as 1 000 m at 100 km/h to 33 kW at 2 558 m, 176 km/h [1-3], durability and reliability remain key challenges. This review reports on the inadequate understanding of behaviour of PEMFC under aeronautic conditions and the lack of predictive methods conducive for aircraft that provide real-time information on the State of Health of PEMFCs. Highlights: The main research findings are -To minimize performance loss due to high altitude and inclination by adjusting cathode stoichiometric ratio. -To improve quality of oxygen-depleted air by controlling operating temperature and stoichiometric ratio. -Need to devise real time prediction methods conducive for determining PEMFC SoH in aircraft.

“…Despite the fact that the nonlinear PEMFC system is precisely linearized by feedback linearization, variation of the parameters can cause degradation in the control performance, particularly when the load varies. Thus, to avoid this degradation, (19) is modified with adding two integral in the closed-loop system [2,24]:…”

“…Adaptive and robust control of the PEMFC is a major concern for many researchers and received an increasing attention among them [10][11][12][13][14][15][16][17][18][19]. Almeida et al introduced an optimal artificial neural network (ANN) based control for the PEMFC in order to obtain an approximated optimal control [10].…”

This paper presents a robust neural network adaptive control for polymer electrolyte membrane (PEM) fuel cells (FCs). Since deviations between the partial pressure of hydrogen and oxygen in PEMFCs lead to serious membrane damage, it is desirable to have a robust and adaptive control to stabilize the partial pressure, which can significantly lengthen their lifetime. Due to inherent nonlinearities in PEMFC dynamics and variations of the system parameters, a linear control with fixed gains cannot control the PEMFC system properly. Therefore, a neural network adaptive control with feedback linearization is developed for this system. With a feedback linearization control only, the performance is deviated in the presence of unknown dynamics and disturbances. Thus, a robust adaptive neural network control is added to the feedback linearization control to reduce the deviation. Simulation results show that the proposed control can significantly enhance the output performance as well as reject the disturbances.

“…Similar control objectives are addressed by designing classical PI and PIDs controllers [15] or enhanced PI tuning based on genetic algorithms [16]. More recently, fault-tolerant control strategies [17] are applied. Typically, the control problem must deal with non-linear behaviors of the plant; however, control oriented linear models such as state-space models [18] and identification models [19] are also developed.…”

Control of the Air Supply Subsystem in a PEMFC with Balance of Plant Simulation

et al. 2017

This paper deals with the design of a control scheme for improving the air supply subsystem of a Proton Exchange Membrane Fuel Cell (PEMFC) with maximum power of 65 kW. The control scheme is evaluated in a plant simulator which incorporates the balance of plant (BOP) components and is built in the aspenONE R platform. The aspenONE R libraries and tools allows introducing the compressor map and sizing the heat exchangers used to conduct the reactants temperature to the operating value. The PEMFC model and an adaptive controller were programmed to create customized libraries used in the simulator. The structure of the plant control is as follows: the stoichiometric oxygen excess ratio is regulated by manipulating the compressor power, the equilibrium of the anode-cathode pressures is achieved by tracking the anode pressure with hydrogen flow manipulation; the oxygen and hydrogen temperatures are regulated in the heat exchangers, and the gas humidity control is obtained with a simplified model of the humidifier. The control scheme performance is evaluated for load changes, perturbations and parametric variations, introducing a growing current profile covering a large span of power, and a current profile derived from a standard driving speed cycle. The impact of the control scheme is advantageous, since the control objectives are accomplished and the PEMFC tolerates reasonably membrane damage that can produce active surface reduction. The simulation analysis aids to identify the safe Voltage-Current region, where the compressor works with mechanical stability.
