Abstract

Model vodikove gorive ćelije je razvijen i implementiran u EMTP softveru. Matematički model vodikove gorive ćelije je izrađen na temelju postojeće literature. Za razliku od većine dostupnih matematičkih modela, implementirani model može simulirati ponašanje bilo koje vodikove gorive ćelije, a koja koristi vodik kao gorivo i zrak kao oksidans. Također, većina postojećih modela zahtjeva niz unutarnjih parametara do kojih se najčešće jedino može doći provođenjem eksperimenata na stvarnoj gorivoj ćeliji. Za razliku od ostalih modela, implementiranom modelu su potrebni podaci iz podatkovne tablice stvarne gorive ćelije na temelju kojih on sam određuje svoje unutarnje parametre. Valjanost implementiranog modela je potvrđena kroz simulacije u EMTP-u i MATLAB-u. Implementirani model je također bio korišten u simulaciji istosmjernog električnog sustava. Zbog potreba simulacije istosmjernog električnog sustava, modeli uzlaznog pretvarača i njegovog sustava za regulaciju napona su također implementirani u EMTP softver.

Abstract (english)

A hydrogen fuel cell stack model was developed and implemented in the EMTP. The mathematical model was developed based on the approach proposed in the literature. Unlike most of the models available in the literature, the implemented model can simulate the behaviour of all fuel cells that use hydrogen as fuel and air as oxidant. Also, most of the proposed fuel cell models require a series of internal fuel cell parameters that can usually be obtained only by performing experiments on a real fuel cell. Unlike them, the model implemented in the EMTP requires several parameters from the fuel cell datasheet. The model uses the datasheet parameters to determine its internal parameters. The model was validated through EMTP and MATLAB simulations. Furthermore, the EMTP fuel cell model was used in a simulation of the DC electrical system. For simulation purposes, models of boost converter and its voltage control system were also implemented in the EMTP.
