20.500.12556/RUL-106837 Predictive virtual modelling framework for performance and platinum degradation modelling of high temperature PEM fuel cells High temperature polymer electrolyte membrane fuel cells (HT-PEMFCs) are a promising and emerging technology that allow for highly efficient low emission small scale electricity and heat generation. Simultaneous reduction of production costs and prolongation of the service life is considered as a significant challenge towards their wider market adoptions, which calls for application of predictive virtual tools during the development process of HT-PEMFC systems. To present a significant progress in the addressed area, this paper presents an innovative modelling framework based on: a) mechanistically based spatially and temporally resolved HT-PEMFC performance model and b) modular degradation modelling framework based on interacting partial platinum degradation mechanisms. Proposed innovative tool chain thus allows for - compared to the current state of the art - more efficient and systematic model supported design of FCs and in-depth understanding of cause and effect chain from FC operation to its degradation. This merit of the proposed modelling framework arises from systematic reflection of FC control parameters in operational parameters of the FC, which are inputs to degradation modelling framework that considers in an interacting manner carbon and Pt oxidation phenomena and Pt dissolution, redeposition, detachment and agglomeration phenomena thereby adequately modelling the causal chain. fuel cells high temperature proton exchange membrane modelling predictive platinum degradation gorivne celice protonska izmenjevalna membrana visoko temperaturna PEM gorivna celica modeliranje napovedovanje degradacija platine true false true Angleški jezik Slovenski jezik Članek v reviji 2019-03-19 11:58:01 2019-03-19 11:58:06 2022-08-19 03:47:05 0000-00-00 00:00:00 2019 0 0 f. 1817-1822 Vol. 158 Feb. 2019 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.43(045) 1876-6102 10.1016/j.egypro.2019.01.426 16520475 16520219 RAZ_Kregar_Ambroz_i2019.pdf RAZ_Kregar_Ambroz_i2019.pdf 1 814F7EF1D75A0633F9B924450DCDDB2A fbeb5689086be01359f3e7b64ae6a8d4c115ad2f48d36a768c733712577f1ac8 62267905-a1b6-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=117600 https://www.sciencedirect.com/science/article/pii/S1876610219304497?via%3Dihub 1 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=117599 Fakulteta za strojništvo 0 0 0
