Abstract

Korištenje fosilnih goriva uzrokuje emisije ugljikovog dioksida (CO2) koje dovode do klimatskih promjena i zagađenja okoliša. Kao alternativa fosilnim gorivima nameću se obnovljivi izvori energije (OIE) sa svojim velikim potencijalom, no zbog njihove intermitentnosti u sustave s OIE uvode se spremnici energije. U tome važnu ulogu dobiva vodik i tehnologije koje se bave njegovom proizvodnjom, pohranom, distrubucijom i iskorištavanjem.
U ovom završnom radu opisan je osnovni princip procesa elektrolize za proizvodnju vodika, te termodinamike koja se odvija tijekom samog procesa.
Naglasak je na elektrolizatoru s protonski izmjenjivom membranom (PEM), čije su komponente prikazane i opisane u ovom radu, kao i način pokretanja i rada cijelog sustava
Ispitan je rad PEM elektrolizatora u realnim laboratorijskim uvjetima, pri različitim parametrima, te su rezultati uspoređeni s podacima navedenim u tehničkoj specifikaciji proizvođača.

Abstract (english)

Climate changes and pollution caused by emission of carbon dioxide (CO2), are the
consequences of using fossil fuels. Alternative to fossil fuels could be renewable energy
sources (RES) with its great potential. Because of its intermittency, in the RES based systems
energy storage is needed. This is where hydrogen and technologies of its production, storage,
distribution and usage have an important role.
This thesis describes the basic principle of process of electrolysis for hydrogen production, and
the thermodynamics that is taking place in this process.
The accent is on proton exchange membrane (PEM) electrolyzer, whose components are shown
and described. It is also described how to start and operate the whole system.
The operating of PEM electrolyzer is tested in real laboratory conditions and compared to the
values in technical specifications given by electrolyzer manufacturer.
