Abstract

V magistrski nalogi sem s pomočjo programske opreme Modelica in Bond graf izvedel modeliranje 7 kW agregata na gorivne celice, katerega uporaba je v Slovenski vojski prisotna od leta 2007. Osnova je bil torej prej omenjeni agregat. S pomočjo dobljenih rezultatov sem prišel do spoznanja, da gorivna celica z leti obratovanja izgublja na električni napetosti, prav toliko pa dobiva na toplotni moči. Prav tako vidimo, da je napetost na sponkah gorivne celice zelo odvisna od porabnika. Ne bo pa izpostavljen problem ekološkega opravičila za uporabo gorivnih celic, v primerjavi z električnimi avtomobili, ki uporabljajo baterije, in njihovo uporabo v prihodnosti, ki temelji na navedbi prednosti in slabosti gorivnih celic. V bližnji prihodnosti je pričakovati,glede na njihov o uporabo ter implementacij o, sprejem vodika kot goriva, namesto običajnih fosilnih goriv.

Secondary abstract:	In the thesis I decided to use with the support of the Modelica Bond Graph software, to carry out the modeling of 7kW generator fuel cell whose use is present in the Slovenian Armed Forces since 2007. The basis is therefore, the aforementioned aggregate. Using the results obtained, I came to the conclusion that the fuel cell with its years of operation the cell voltage decreases, as equally as it increases the heat output. In short I presented the program Modelica for which I can confirm that it is a great alternative to Simulink . At the same time we see that the voltage at the terminals of the fuel cell is very dependent on the enduser. I did not expose the problem of ecological justification for the use of fuel cells in comparison with electric cars which use batteries and their use in the future, based on the indication of the advantages and disadvantages of fuel cells. It is expected their use and implementation in the near future, the adoption of hydrogen as a fuel instead of conventional fossil fuels.
