This paper presents a fuel cell simulation model, built to emulate its electrical behavior by using a DC-DC converter and loads. Therefore, a cascade control loop is used in this work to make the fuel cell emulator working with high efficiency.Simulations results are presented to validate emulator design and robustness of the control strategy using Matlab/Simulink. The structure of a proposed system is simple for its realization on a system dSPACE. Otherwise, a test of a commercial fuel cell is performed whose purpose is to determine the voltage-current characteristic of a fuel cell.

“…Cirrincione et al report in [31] a similar development, modeling the polarization curve and charge double layer effect, and using a power stage based on a DC/DC buck converter. Sirisukprasert et al [32] follow the same simple modeling and DC/DC buck converter-based power stage approach. It is mainly intended to support DC/AC inverters' design.…”

“…In this example, a 15 V power source is considered, and therefore the electric power that must be dissipated is 101 W. Rewriting Equation (32) to take into account the number of linear regulators (n lg ) required to address this practical case, and also considering the thermal resistance reduction factor (K TR ) generated by the forced air system, the following equation is obtained:…”

A fuel cell-based power systems emulator designed to test devices and loads intended to interact with real prototypes is presented. The emulator uses a digital processing device and electrical power systems, evaluating the impact of using either switching or linear power stages in the emulator capabilities. A real fuel cell prototype is emulated using a parameterized physical fuel cell model, which is computed online by a digital device. Also, several power stages not previously used specifically for this application, with different efficiencies and performances, were developed and analysed. One of the power stages was based on a two-inductor step-down DC/DC converter for a switching power stage instead of the classical buck structure that is more prone to duty cycle saturation in transients at low output voltages. The other ones used high-power operational amplifiers for a linear power stage and linear regulators for a scalable linear power stage. Finally, the emulation system and the power stages were evaluated and validated using experimental data of a real fuel cell prototype. SWITCHING AND LINEAR POWER STAGES EVALUATION 477 power stages developed to interact with the electrical loads are described and analysed. In Section 4, the experimental results are reported. Finally, conclusions of the work are given in Section 5. FUEL CELL EMULATION TOPOLOGYThe fuel cell emulation system has three main parts. First, a mathematical model that describes the behaviour of the selected fuel cell is used to calculate the emulator output. Second, a digital system that executes a real-time algorithm, which processes the selected mathematical model, is used to control the emulator power stage. Third, the emulator power stage that interacts with the electrical loads. This power stage must follow the dynamics defined by the mathematical model, and this implies an appropriate control of this power system. Also, the power stage must be electrically efficient or have an effective thermal dissipation system in order to avoid damages in low voltage-high current operating points. Other characteristics like low-cost, simplicity, portability and scalability have been also taken into account in the design process.

“…A fuel cell emulator based on a computer-controlled power rectifier AC/DC of a proton exchange membrane (PEM) fuel cell was proposed in [6]. In [7], an emulator for a PEM fuel cell was developed using a current source converter and a buck DC/DC converter; this emulator provides very precise voltage and power characteristics. In [8], a fuel cell real-time simulator oriented to evaluate the performance of DC/DC and DC/AC converters was presented.…”

This article presents a study of a proton exchange membrane fuel cell system taking into account the fuel starvation phenomenon; this phenomenon causes serious problems when the load changes rapidly. Therefore, oxygen and hydrogen excess ratios are two important issues that should be controlled in the proton exchange membrane fuel cell. To verify the influences of this phenomenon on the fuel cell performances, a proton exchange membrane fuel cell emulator system is realized with dSpace (Cedex, France). In addition, a supercapacitor as an energy storage system is proposed as another solution to prevent this phenomenon, improve performance, and increase lifetime. Experimental results illustrate that the proposed emulator is an excellent tool for testing and experimenting energy storage systems and electronic devices for proton exchange membrane fuel cell applications and determine their impact on the fuel cell characteristics.
