The aim of this work is to develop a dynamic equivalent scheme of the fuel cell, taking into account eddy currents in the conductive parts of the structure, to offer a practical way to determine the parameters of this circuit and also to show the adequacy of the scheme and parameters by numerical simulation and comparison with experiment. Fuel cells, as a rule, are connected to the voltage converters, which create a high-frequency component of the main fuel cell current and eddy currents in the conductive parts. The problem is that the effect of these currents on the characteristics of the fuel cell-based power plants has not been studied. To determine the parameters of the proposed equivalent scheme, we use experiments and calculations of transient modes of the fuel cell. The main result of the work is the possibility and feasibility of calculating circuits with fuel cells, taking into account the influence of eddy currents. This effect depends both on the design of the fuel cell and on the parameters of the circuit to which it is connected. From this it follows that, in general, it is necessary to take into account the influence of eddy currents of the fuel cell. The refusal of this accounting is possible, but in each specific case it must be justified.
