Hybrid methodology for efficient on the fly (re)parametrization of proton exchange membrane fuel cells electrochemical model for diagnostics and control applicationsKravos, Andraž, strojnik ; Kregar, Ambrož, 1987- ; Katrašnik, TomažSuccessful parametrization and re-parametrization of the models used in PEMFC observer applications is instrumental to assure ideal control of the system. To increase ease of parametrisation and ... accuracy of parameter determination, this paper presents framework of twin analytical ansatzes for modelling PEMFC response in time and frequency domains sharing same set of calibration parameters. Owing to thermodynamically consistent modelling basis of the twin models, which are based on electrochemical model with state-of-the-art extrapolation capabilities and replication of the experimental data with one set of calibration parameters, they are valid in all current density regions. Furthermore, unique sharing of the calibration parameters enables unprecedented enrichment of the dataset that can be used to determine values of model's calibration parameters with higher certainty or enhances identification of individual calibration parameters that are otherwise harder to be uniquely determined. Additionally, proposed hybrid methodology also enables a significant reduction in the measurement time and enable re-parametrization on the fly.Vir: PRiME 2020 [Elektronski vir] : Polymer Electrolyte Fuel Cells & Electrolyzers 20 (PEFC&E 20) (Vol. 98, no. 9, 2020, str. 13-24)Vrsta gradiva - prispevek na konferenciLeto - 2020Jezik - angleškiCOBISS.SI-ID - 30901507
