Abstract
In this doctoral dissertation, the influence of the magnetic and optical fields on the process of alkaline water electrolysis has been analysed. For that purpose, an experimental setup was designed and an electrolyzer was constructed. In the scope of the research implementation of the nickel (Ni) foam electrodes instead of smooth surface Ni electrodes was analysed. Based on the experimental results an adjustment of the mathematical model for the calculation of energy efficiency was proposed. The results of the research have been presented in detail, and conclusions were drawn out. Positive effects of the influence of the magnetic and optical fields, as well as the application of foam electrodes are observed, which means that the original hypothesis of the research was confirmed.
Abstract (croatian)
Razvoj vodikovih tehnologija u velikom je porastu diljem svijeta, među kojima je i proizvodnja vodika u alkalnim elektrolizatorima. Glavna tema ovoga doktorskoga rada je istraživanje utjecajnih čimbenika na energetsku učinkovitost alkalnoga elektrolizera. Analizirani utjecajni čimbenici uključuju primjenu magnetskoga i optičkoga polja, te primjenu elektroda od Ni pjene. Prvo poglavlje doktorske disertacije je UVOD. U ovom poglavlju prikazan je pogled na energetsku tranziciju s gospodarstva temeljenoga na fosilnim gorivima na gospodarstvo temeljeno na vodiku, prema ugljično neutralnom društvu. Zatim slijedi detaljna analiza trenutnog stanja vodikovih tehnologija, s fokusom na proizvodnju vodika alkalnom elektrolizom vode. Na kraju su opisani ciljevi rada, hipoteza, metode, te plan istraživanja. Nakon uvoda, u poglavlju EKSPERIMENTALNA ISTRAŽIVANJA detaljno je opisana eksperimentalna staza. Najprije je analizira primjena magnetskoga i optičkoga polja, a potom je detaljno prikazan razvoj i prilagodba dizajna elektrolizatora i elektroda. Razrađen je postupak mjerenja i obrade podataka, uključujući i proračun energetske učinkovitosti. Sljedeće poglavlje je MATEMATIČKI MODEL gdje je prikazana prilagođena verzija matematičkoga modela za proračun energetske učinkovitosti. Na temelju rezultata eksperimentalnih mjerenja model je prilagođen korištenjem softvera MATLAB/Simulink te je prikazana uspješnost prilagodbe. U poglavlju REZULTATI prikazani su rezultati eksperimentalnoga istraživanja koji su detaljno analizirani te su doneseni zaključci. Završno poglavlje je ZAKLJUČAK u kojemu je dan sažetak istraživanja s razrađenim rezultatima. Opisana je analiza potvrde hipoteze s navedenim znanstvenim doprinosima istraživanja. Na samom kraju predstavljena su planirana buduća istraživanja.
