Abstract

U ovom radu ispitivao se utjecaj građe elektrokemijske ćelije na rezultate elektrokemijskih ispitivanja. Metoda koja se koristila je elektrokemijska impedancijska spektroskopija (EIS). Mjerenje se provodilo na dvije podloge: podlozi od čistog bakra i patiniranoj brončanoj pločici. Ispitao se utjecaj građe elektrokemijske ćelije na rezultate koji su dobiveni s elektrolitom na bazi hidrogelova PVA i hidrogelova na bazi agara kao zamjenom za vodenim elektrolit u standardnim elektrokemijskim ćelijama. Mjerenja su se provodila u dvoelektrodnom i troelektrodnom sustavu sa različitim protu i referentnim elektrodama. Snimljeni su impedancijski spektri u rasponu frekvencija od 0,01 Hz do 100000 Hz.

Abstract (english)

In this work, the influence of an electrochemical cell design on the results of electrochemical tests was examined by electrochemical impedance spectroscopy (EIS) measurements. The experiment was conducted on two substrates a pure copper substrate and a patinated bronze plate. The influence of electrochemical cell structure on the results obtained with electrolyte based on PVA hydrogels and agar based hydrogels as a substitute for aqueous electrolyte in standard electrochemical cells was conducted. Measurements were performed in a two-electrode and three-electrode system with different counter and reference electrodes. Impedance spectres of the coatings were recorded in the range between 0,01 Hz and 100000 Hz.
