Abstract

The article presents a comparative analysis of the time constants of the main processes in theSOFC. The analysis was used to determine those processes most relevant to the modeling of anenergy system comprising a fuel cell. The hybrid system, in addition to the fuel cell, has otherdevices (such as compressors, turbines, heat exchangers, etc.) working with it that may limitpermissible ranges of parameter changes during transient processes. On the other hand, fuel cellsaect other devices making up the system, including by restricting their operation in terms ofdynamic responses.Determination of time constants of the main processes in the cell and their analysis and comparisonwith time constants of other devices will allow selection of the most important processesfrom modeling point of vies and simplify the dynamic fuel cell model, so the class of fuel cell willmatch classes of models of other system elements.
