Abstract
Vodik je jedan od glavnih rješenja za pohranu električne energije, te je izvrstan link prema obnovljivim izvorima energije (OIE). Električna energija pohranjuje se u vodik na način da se vodik proizvede elektrolizom vode korištenjem OIE. Takav proces u potpunosti je bez popratnih štetnih emisija. U ovom radu naglasak je upravo stavljen na istraživanje značajki laboratorijski izvedenog svežnja elektrolizatora kojega čine tri članka. Prema tipu elektrolita to je alkalni elektrolizator, a prema tipu konstrukcije to je elektrolizator bipolarne izvedbe. Mjerenja su se provodila unutar Laboratorija za energetska postrojenja pri čemu se električna energija potrebna za pogon elektrolizatora dobivala iz laboratorijskog izvora istosmjerne struje. Eksperimentalnim ispitivanjima svežnja elektrolizatora snimala se radna (U-I) karakteristika i koja je uspoređena s U-I karakteristikom elektrolizatora kojega čini jedan članak sličnih dimenzija. Nadalje, ispitana je brzina proizvodnje vodika, te učinkovitost elektrolizatora. Također, s obzirom na to da su ovo prva značajnija mjerenja ovoga svežnja elektrolizatora, posebna pažnja posvećena je na kvalitetu njegova rada.
Abstract (english)
Hydrogen is one of the major energy storage solutions, and is an excellent link to renewable energy sources (RES). Electricity is stored in hydrogen in such a way that hydrogen is produced by electrolysis of water using RES. Such a process is completely free of harmful emissions. In this thesis, the emphasis has been put on investigation of the features of a laboratory constructed electrolyzer stack consisting of three cells. According to the type of electrolyte it is an alkaline electrolyzer, and according to the type of construction it is an electrolyzer of bipolar design. Measurements were carried out within the Power Engineering Laboratory whereby the electricity required to power the electrolyzer was obtained from a laboratory direct current source. By experimental testing of the electrolyzer stack it was recorded the operating (U-I) characteristic which was compared with a U-I characteristic of a single cell electrolyzer of similar dimensions. Furthermore, the rate of hydrogen production and the efficiency of the electrolyzer were examined. Also, since these are the first significant measurements of this electrolyzer stack, special attention has been paid to the proper operation of the electrolyzer.
