Abstract

The demand for improved air quality due to global environmental issues promotes the development of various sustainable energy sources. Hydrogen gas, a clean-burning fuel, can be produced through the electrolysis process. This approach utilizes a dry cell electrolyzer equipped with a polyvinyl alcohol (PVA) membrane, which acts as a separator for the two electrodes, preventing hydrogen and oxygen from mixing. It is also to increase the composition of hydrogen gas significantly. The application of KOH electrolyte can increase the electric current, which contributes to the increased power requirement and more significant hydrogen gas production. The hydrogen produced is converted into electrical energy utilized to supply charging stations and mobile phones as loads using hydrogen fuel cells with the results of charging successful (CS) and charging failed (CF) status. KOH electrolyte variation are 0 M, 0.04 M, 0.07 M and 0.11 M sequentially in each hydrogen production experiment without using PVA membrane and by using PVA membrane thickness of 1.5 mm and 3 mm. For electrolysis using PVA membrane thickness of 1.5 mm requires power of 26.81 VA, 67.51 VA, 92.63 VA, 211.82 VA resulting in hydrogen composition of 71.50%, 89.10%, 80.50%, 84.60% and hydrogen fuel cell produces power of 0 VA, 2.71 VA, 2.06 VA, 2.98 VA with CF, CS, CS, CS status. The highest hydrogen composition of 89.10% was obtained from the electrolysis of PVA membrane thickness of 1.5 mm using KOH electrolyte concentration of 0.04 M. But no less important electrical power efficiency (comparison of electrical power requirements in dry cell electrolyzer and electrical power generated in hydrogen fuel cell) highest of 17.79% obtained in dry cell electrolyzer with PVA membrane thickness of 3 mm using KOH electrolyte concentration of 0.04 M.
