20.500.12556/RUL-171898 Vpliv relativne vlažnosti na delovanje visoko-temperaturne gorivne celice s protonsko izmenjevalno membrano Effect of relative humidity on the performance of a high-temperature proton exchange membrane fuel cell V zaključni nalogi je analiziran vpliv relativne vlažnosti pri različnih koncentracijah ogljikovega monoksida v reformiranem plinu, na delovanje visokotemperaturne gorivne celice s protonsko izmenjevalno membrano. Eksperimentalni del je bil opravljen na Fakulteti za strojništvo v Ljubljani, v Laboratoriju za termoenergetiko, na merilni postaji Greenlight, kjer so bili delovni parametri ustrezno nadzorovani in beleženi. Meritve bile razdeljene v tri sklope glede na vsebnost ogljikovega monoksida in na štiri referenčne meritve, vse pa so predstavljene v obliki polarizacijskih krivulj. Analiza je pokazala, da v opazovanem območju vlažnosti, ta pozitivno vpliva na zmogljivost gorivne celice, ki se povečuje linearno z večanjem relativne vlažnosti goriva. Poleg tega je bilo ugotovljeno, da je celica kljub prisotnosti ogljikovega monoksida ohranila svojo prvotno zmogljivost, kar potrjuje njihovo odpornost in možnost uporabe z reformiranimi plini. The thesis analyzes the influence of relative humidity at various carbon monoxide concentrations in reformate gas on the performance of a high temperature proton exchange membrane fuel cell. The experimental work was conducted at the Faculty of mechanical engineering in Ljubljana, in the Laboratory for thermal energy, using a Greenlight test station, where operating parameters were accurately controlled and recorded. The measurements were divided into three sets based on carbon monoxide concentration, along with four reference measurements, all presented in the form of polarization curves. The analysis showed that the performance of the fuel cell increases linearly with higher relative humidity of the fuel. Additionally, it was found that the cell maintained its original performance despite the presence of carbon monoxide, confirming its resilience and suitability for use with reformate gases. visokotemperaturna PEM gorivna celica parni reforming metanola relativna vlažnost reformni plin polarizacijska krivulja vodik high-temperature PEM fuel cell methanol steam reforming relative humidity reformed gas polarization curve hydrogen true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2025-09-04 08:31:01 2025-09-04 08:31:03 2025-09-25 03:38:39 0000-00-00 00:00:00 2025 0 0 XIII, 38 f. 2025 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.352.6:543.275.1:546.262.3-31(043.2) 275363 249328643 43232.pdf 43232.pdf 1 20EB864AA3CAADC02343CE782D040262 1968dd5522d86d486debee5b90e1cdfc4bdf405be017d60a75979822158cd56e 94e897aa-8958-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=215464 Fakulteta za strojništvo 0 0 0
