Abstract

The commonly consumed energy currently comes from fossil fuels that cannot be renewed that decrease over time. The depletion of fossil energy reserves encourages people to find renewable energy sources, and one of them comes from hydrogen fuel. By utilizing water, which is very abundant on earth, hydrogen can be a potential alternative fuel. The process of producing hydrogen from water is called the electrolysis process of water. In this study, a water electrolyzer prototype was designed. The amount of water used in this study is 6 liters varied with variable concentration changes of 10, 20, 30, 40, and 50% NaOH solutions. The optimal production of hydrogen gas achieved at the concentration of 50% NaOH solution to produce a gas of 4.5902 liters and the moll percentage of hydrogen in the product is 78.34%. The results of gas chromatography analysis show that the hydrogen content in the product is 77.85%; 10.86%, nitrogen 11.24%; and carbon dioxide 0.07%. The electrical efficiency obtained reaches 82% with the heat loss of 17.92%.
