20.500.12556/RUL-152685 Hybrid methodology for parametrisation of proton exchange membrane fuel cell model for diagnostics and control applications Electrochemical impedance spectroscopy (EIS) is a very powerful tool for the diagnosis and characterisation of fuell cells (FC). However, there is still a lack of physico-chemically consistent models that include parameters with a clear physical meaning and can be related to intrinsic parameters of FC. To fill this knowledge gap, this paper presents a novel, mechanistically-based and computationally-efficient FC modeling framework for time and frequency domain simulations. Furthermore, the model consistently handles forward and backward reactions, ensuring its validity at all current densities. These features enable the development of a hybrid methodology for parameterising the FC model in both domains, resulting in unprecedented accuracy in determining the internal states around which the EIS perturbation is applied. Furthermore, innovative modeling framework incorporates a 1D analytical solution of FC impedance that for the first time accounts for both electrodes, the membrane and individual effects of the electrodes coupled to the respective GDL and channel, all significantly impacting the accuracy of the model. This was confirmed by state-of-the-art reproduction of experimental data with R$^2$ values exceeding 0.965 for data not used in the parameterisation. The presented modeling framework thus provides a modelling basis for observer functionalities beyond the state-of-the-art. fuel cells electrochemical impedance spectroscopy analytical solution parametrisation realtime capable modelling gorivne celice elektrokemijska impedančna spektroskopija analitična rešitev parametrizacija delovanje v realnem času modeliranje true false true Angleški jezik Slovenski jezik Članek v reviji 2023-12-04 13:25:49 2023-12-04 13:25:55 2023-12-05 03:41:06 0000-00-00 00:00:00 2023 0 0 Str. 1-27 no. 11, art. 114522 Vol. 170 Nov. 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.35 1945-7111 10.1149/1945-7111/ad07a7 171709443 Kravos_..._-_Hybrid_Methodology_for_Parametrisation_of_Proton_Exchange_Membrane_Fuel_Cell_Model_for_Diagnostics_and_Control_Applications.pdf Kravos_..._-_Hybrid_Methodology_for_Parametrisation_of_Proton_Exchange_Membrane_Fuel_Cell_Model_for_Diagnostics_and_Control_Applications.pdf 1 55C5417AEB5837D9010680DCEA9B2B4E fdec7969de40a805be8cf8eaa39a2fed4749bb1de29226784b9d78b4a28e998d 7fe2704e-92a3-11ee-9ca9-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=178297 https://iopscience.iop.org/article/10.1149/1945-7111/ad07a7 1 46221c13-92a0-11ee-9ca9-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=178294 Fakulteta za strojništvo 0 0 0
