Abstract
Vodikov membranski gorivni članak je primjenjiv u pomorstvu zato što je kod putovanja trgovačkim i teretnim brodovima brzina plovidbe konstantna. Opterećenje pogona broda se ne mijenja nakon dostizanja projektne brzine, što odgovara sprječavanju stvaranja kapljica vode unutar kanala svežnja gorivnih članaka. Iznimno, promjena opterećenja se može dogoditi zbog dodatnog otpora valova prilikom nailaska na valove i ubrzanja broda, s time da se takve oscilacije mogu pokriti baterijskim paketom, koje će pokriti razliku opterećenja na svežanj gorivnih članaka. Iz tog razloga se ovaj diplomski bavi problematikom modeliranja, optimiranja i eksperimentalnog ispitivanja vodikovih membranskih gorivnih članaka za moguću upotrebu u pomorstvu. Eksperimentalno istraživanje vodikovog membranskog gorivnog članka s 3 serpentine je vršeno kako bi se mogao razviti računalni model za predviđanje, razvoj optimalne geometrije i poboljšanje performansi jediničnog gorivnog članka, te za implementaciju poboljšanja u svežanj gorivnih članaka. Rezultat optimiranja je geometrija s 4 serpentine, koja se koristi za svežanj. Direktna numerička simulacija nije provedena, ali geometrija jediničnog gorivnog članka se minimalno prilagodila, kako te promjene ne bi utjecale na performanse gorivnog članka i kako bi se ta geometrija implementirala u svežanj gorivnih članaka. Potrebno je razviti sustav hlađenja, koji bi mogao odvesti toplinu iz svežnja gorivnog članka, ali u ovom diplomskom radu se nije bavilo termalnom analizom svežnja gorivnih članaka.
Abstract (english)
PEM fuel cell has a lot of potential for the shipbuilding industry because commercial and cargo vessel move at project speed, which is constant. Engine load is not changed after the project speed of ship is accomplished, which is a good trait for preventing water droplet accumulation inside of PEM fuel cell stack channels. Exceptionally load can be changed while there are sea waves and if a vessel is accelerating, that oscillations can be covered by a battery pack that will dissolve the load difference of the PEM fuel cell stack under working conditions. For that purpose, this master’s thesis conducts research about computational fluid dynamics optimization and experimental validation of PEM fuel cells. Experimental research of PEM fuel cell with 3 serpentines has been conducted with the purpose of creating a computational fluid dynamics model for the prediction and development of optimal bipolar plates geometry, improving single cell fuel cell performance and consequently implementing improvements to fuel cell stack development. The optimization process result is bipolar plate geometry with 4 serpentines, that have been used for fuel cell stack. Direct CFD simulation wasn’t conducted, but the geometry of the optimal fuel cell was adapted as low as possible so that adaptations don’t affect the performance of single cell fuel cell. It is necessary to develop a cooling system which could manage heat transfer from the inner part of the fuel cell stack, but in this master thesis heat transfer analysis of the fuel cell stack wasn’t conducted.
