“…The dynamic model outlined in [2,8,18] incorporates the effects of double layer charging capacitance with the activation overvoltage term. This results in a first order model, where a sudden change in cell current is associated with a slower variation in output voltage [2,8,22].…”

“…An overview of the relevant literature, to date, shows three major issues, which give rise to dynamic phenomena within a fuel cell. These are, the dynamics of fuel cell electrochemistry [7,8,9,18,20], thermodynamics [11,17], and reactant flow dynamics [15,16,19,25,26]. Any attempt towards unifying these three aspects within one empirical model together with experimental verification is almost non-existent.…”

In this paper an approach for the dynamic modelling of polymer electrolyte membrane fuel cells is presented. A mathematical formulation based on empirical equations is discussed and several features, exhibiting dynamic phenomena, are investigated. A generalized steady state fuel cell model is extended for the development of a method for dynamic electrochemical analysis. Energy balance and reactant flow dynamics are also explained through physical and empirical relationships. A well‐researched system (Ballard MK5‐E stack based PGS‐105B system) is considered in order to understand the operation of a practical fuel cell unit. Matlab‐SIMULINKTM has been used in simulating the models. The proposed method appears to be relatively simple and consequently requires less computation time. Simulation results are compared with available experimental findings and a good match has been observed.

“…The study of the mass transport in the CCL is complex, yet has been treated in the literature with certain simplifications and approximations. Berger et al [2,3,4,5,6] considers that diffusion occurs perpendicularly to the surface of the electrochemical reaction. Under this condition is possible to assume that the drop of the reactant concentration is linear.…”

A mathematical model to simulate the electrochemical impedance spectrum in the frequency domain and the current distribution in the time domain of polymer electrolyte fuel cell cathode catalyst layer (CCL) operated at high currents has been developed. In the model, Fick’s second law in the frequency domain is solved to define oxygen distribution through CCL. The rate of oxygen transportation and proton conductivity are related to the current distribution equation reported in the authors’ previous study for low current operations. The model, compared against the frequency response of an experimental impedance spectrum, is then converted into the time domain using the inverse Laplace transform method. The results show the nonsteady oxygen diffusion in the CCL which allows equilibrium to be established between the bulk concentration supplied at the gas diffusion layer boundary and the surface concentration of the oxygen within the CCL. The developed model can be applied to unveil the effect of kinetic, ohmic, and mass transport mechanisms on current distribution through the thickness of the CCL from the measured impedance results.

This paper presents a new method to design nonlinear feedback linearization controller for polymer electrolyte membrane fuel cells (PEMFCs). A nonlinear controller is designed based on nonlinear model to prolong the stack life of PEM fuel cells. Since it is known that large deviations between hydrogen and oxygen partial pressures can cause severe membrane damage in the fuel cell, feedback linearization is applied to the PEM fuel cell system, thus the deviation can be kept as small as possible during disturbances or load variations. To obtain an accurate feedback linearization controller, tuning the linear parameters are always important. So in proposed study NSGA_II method was used to tune the designed controller in aim to decrease the controller tracking error. The simulation result showed that the proposed method tuned the controller efficiently.
