Abstract

Zagotavljanje ustreznih obratovalnih pogojev gorivnoceličnega sklopa predstavlja zahteven kontrolni in inženirski izziv, saj združuje obratovalne pogoje iz različnih domen. Zato je za hkratno optimizacijo učinkovitosti, zagotavljanje trajnosti, upravljanje vsebnosti in dinamike kapljevite vode ter preprečevanje pregrevanja nujna uporaba modelsko podprtega nadzora. V diplomski nalogi je predstavljen in implementiran numerični modelski okvir podpornega sistema gorivnoceličnega sklada s protonsko izmenjevalno membrano za uporabo v kontrolnih aplikacijah in aplikacijah modelsko podrtega razvoja tako v transportnem kot energetskem sektorju. Modeliran podporni sistem je razvit v programskem okolju Python in zajema kompresor, sesalni kolektor, hladilnik in vlažilnik zraka, katodo gorivne celice ter izpušni kolektor. Na podlagi zunanjih robnih pogojev je model analiziran, verificiran in optimiziran. Hitrost izračuna modelskega okvirja pa omogoča izračun v realnem času, pri čemer je model stabilen tudi z uporabo dinamičnih zunanjih robnih pogojev.

Secondary title: Development of a support system model of the fuel cell stack for use in control and model-driven development applications
Secondary abstract: Ensuring proper operating conditions of a fuel cell assembly is a demanding control and engineering challenge, as it combines operating conditions from different domains. Therefore, in order to simultaneously optimize efficiency, ensure sustainability, manage the content and dynamics of water, and prevent overheating, the use of model-supported control is essential. In this thesis, a numerical model framework of the fuel cell fund support system with a proton exchange membrane is presented and implemented for use in control applications and applications of model-driven development in both the transport and energy sectors. The modeled support system is developed in Python software environment and includes a compressor, supply manifold, cooler and humidifier, fuel cell cathode and return manifold. Based on external edge conditions, the model is analyzed, verified and optimized. However, the calculation speed of the model frame allows for real-time calculations, whereby the model is stable even when using dynamic external edge conditions.
