“…On the contrary, parameter C dl increases slightly at high temperatures, however, in order to simplify the model, it is considered to be independent of temperature (C dl = 4.9183 F). With regard to the ohmic resistance, for a temperature of 60 °C, this acquires a value of 0.0012 Ω (0.18 Ω·cm 2 ), similar to those obtained in [45,46]. The values of the said coefficients are shown in Table 1.…”

This paper reports on the modelling of a commercial 1.2 kW proton exchange membrane fuel cell (PEMFC), based on interrelated electrical and thermal models. The electrical model proposed is based on the integration of the thermodynamic and electrochemical phenomena taking place in the FC whilst the thermal model is established from the FC thermal energy balance. The combination of both models makes it possible to predict the FC voltage, based on the current demanded and the ambient temperature. Furthermore, an experimental characterization is conducted and the parameters for the models associated with the FC electrical and thermal performance are obtained. The models are implemented in Matlab Simulink and validated in a number of operating environments, for steady-state and dynamic modes alike. In turn, the FC models are validated in an actual microgrid operating environment, through the series connection of 4 PEMFC. The simulations of the models precisely and accurately reproduce the FC electrical and thermal performance.

“…In (6), A is the cell's active area [cm 2 ] and there are different values of it reported in the literature for the same Nexa FC like 100 cm 2 in [35], 110 cm 2 in [36], 122 cm 2 in [31], etc. Therefore, the cell's active area will be another parameter that needs to be estimated.…”

This paper presents the parameter identification of an equivalent circuit-based proton exchange membrane fuel cell model. The model is represented by two electrical circuits, of which one reproduces the fuel cell's output voltage characteristic and the other one its thermal characteristic. The output voltage model includes activation, concentration, and ohmic losses, which describe the static properties, while the double layer charging effect, delays in fuel and oxygen supply, and other effects provide the model's dynamic properties. In addition, a novel thermal model of the studied Ballard's 1.2 kW Nexa fuel cell is proposed. The latter includes the thermal effects of the stack's fan which significantly improve the model's accuracy. The parameters of both, the electrical and thermal, equivalent circuits were estimated on the basis of experimental data by using an evolution strategy. The resulting parameters were validated by the measurement data obtained from the Nexa module. The comparison indicates a good agreement between the simulation and the experiment. In addition to simulations, the identified model is also suitable for usage in real-time fuel cell emulators. The emulator presented in this paper additionally proves the accuracy of the obtained model and the effectiveness of using an evolution strategy for identification of the fuel cell's parameters.

High Fidelity Model for Proton Exchange Membrane Fuel Cell Power Module Considering Internal Power Losses

A high‐fidelity model has been developed in this paper to characterize a proton exchange membrane (PEM) fuel cell power module. The uniqueness of this model is that it takes into account of the internal temperature of the stack and internal power consumptions by the auxiliary systems. To simplify the model representation, an equivalent circuit model is developed by using operating condition dependent fictitious circuit components. The parameters of these components are nonlinear functions of fuel cell operating conditions, most notably, the output power level and the stack temperature. The specific values of these parameters are determined through a series of experiments on a physical fuel cell power module. The data are then used to construct a nonlinear model to cover a wide fuel cell operating range. To validate the developed model, five characteristic features are used in the experiments. Comparing against the experimental results, it is shown that the developed model produces the minimal amount of errors in comparison with the theoretical model, and a previously developed model. When used to represent a physical fuel cell power source in practice, this model improves the quality of control system design and analysis.
