“…The splitting frequency would be evaluated according to the FC requirements and performance characteristics. It is noted in Talj et al (2011) that at 50 mHz, the fuel cell system response can recover losses and dynamic performance compromise. For this reason, the filtering frequency is taken at this rate in this work.…”

Purpose The purpose of this paper is to propose and compare two energy management strategies (EMSs). First, a classic method based on frequency separation with fixed limits on fuel cell (FC) power is presented and tested. Then, the improvement of the classic strategy is developed and implemented when the main enhancements are its ease of implementation, hydrogen economy and extending hybrid source lifetime. Design/methodology/approach The proposed EMS is developed using an online variable power limitation of the FC depending on the battery state of charge while ensuring that the energy of batteries remains in its operating depth of discharge (DOD) range. Findings In the objective to show the benefits of the developed strategy, a comparative analysis was conducted between two strategies. The simulation and experimental results show the effectiveness and gains obtained by the improved energy management system (IEMS) in terms of fuel economy (13 per cent) and decreasing the applied stress on the FC (22 per cent) which leads to a longer life span of the whole system. Originality/value The proposed approach is developed and tested by simulation. To confirm it, a test bench has been assembled as hardware in the loop (HIL) real-time system. The presented experimental results confirm the efficiency and show the providing gains of the IEMS.

“…An FC system consists of many cells connected in series to provide the desired output terminal voltage and current, and exhibits a nonlinear I – V characteristic [21,22]. Furthermore, the FC system is a complex device with many auxiliary components.…”

“…More precisely, in low dynamic conditions, the FC characteristics can be considered as a voltage source with ohmic, kinetic, and mass transfer resistances. The relationship between the FC voltage v FC and the output current i FC is given by the following equations: where A Cel is area of each cell, N is the stack cell number, E Cel is the reversible cell voltage, R is the membrane area specific resistance, A is the Tafel coefficient, I Stack is the stack current, m and n are the two coefficients of the mass transfer equation, and α , β , and γ and are the coefficients of the second‐order model approximating I Stack as function of the output current i FC [21,22].…”

A hybrid power system based on a fuel cell (FC) and an energy storage system appears to be very promising for satisfying the high energy and high power requirements of automotive applications in which the power demand is impulsive rather than constant. This paper deals with the use of a hybrid energy storage system with the battery (BAT)/ultracapacitor (UC) as ancillary power source in FC electric vehicles. The energy management strategy (EMS) is one of the most important issues for the efficiency and performance of such systems. The designed EMS uses a splitting method, allowing a natural frequency decomposition of the power demands. It takes into account the slow dynamics of FC and the state of charge of the UC and BAT. A simulation is conducted using MATLAB/SIMULINK software in order to verify the effectiveness of the proposed control strategy. It confirms the performance of the control method and also demonstrates the robustness and stability of the control strategy with good tracking response (transient performance), low overshoot, zero steady‐state error, and control flexibility during a power demand cycle. © 2014 Institute of Electrical Engineers of Japan.

“…[17]. Experimentally, the polarization curve is also impacted by the transient load use, which causes a hysteresis effect on the dynamic characteristics of PEMFC stack [18]. Based on several studies, the hysteresis effect occurs due to several reason such as double layer charging effect [19] and its interaction with activation losses [20] and water management in the cells [21].…”

Testing of proton exchange membrane fuel cell system is one of the most important issues due to the cost and security reasons in railway applications. To reduce the cost, it would be necessary to have a representative simulation model for this case. Having an accurate model of proton exchange membrane fuel cell system requires considering several auxiliary circuits. However, in industrial application, the accurate model of proton exchange membrane fuel cell system and corresponding information are not often provided by the designer. Moreover, the simplicity and representativity of model is required to be compatible with overall traction chain model. The model has to be suitable for system simulation and not design purpose. In this paper, a simplified model of PEMFC system is proposed using the experimental profile mission. The impact of all the environment system of proton exchange membrane fuel cell stack is estimated using the average of polarization curve on several operational points. The parameter identification process is applied, and the obtained parameters are then inserted on the overall system of fuel cell stack. The experimental data obtained through train is compared with the consecutive simulation results.
