The Effect of Electric Current on the Production of Brown’s Gas using Hydrogen Fuel Generator with Seawater Electrolytes

Abstract

Abstract The decline in crude oil production in Indonesia is a burden for the Indonesian people. Therefore, Indonesia needs alternative energy or innovation that aims to review the use of petroleum fuels. One alternative energy is the use of hydrogen fuel (H2). Hydrogen gas can be obtained by breaking air compounds (H2O) into hydrogen-oxygen hydrogen gas (HHO) which is brown by electrolysis. Water electrolysis is the decomposition of water compounds into oxygen and hydrogen gas by using an electric current through water. The current will conduct electricity to the electrodes so that a reduction reaction will occur at the cathode and form hydrogen gas. To speed up the electrolysis process, we need an electrolyte solution that conducts electricity. In general, the electrolysis process is carried out to produce oxygen gas and hydrogen gas using alkaline solution. Alkaline solution used is sea water-electrolyte. The solution is a strong electrolyte that can conduct electric current well. The electrodes used are stainless steel pipe which is resistant to corrosion with insulating material added cotton fabric that serves as an insulator or barrier zone between the cathode and the anode. By designing a hydrogen fuel generator, hydrogen gas may be generated based on the effect of electric current. Variations of the electrical current used is 3A, 6A, 9A, 12A, 15A, 18A, and 21A. The higher the electrical current supplied to the production of hydrogen gas will be many more. The production of hydrogen gas is the most widely produced on the current 21A with 0.0478 LPM of hydrogen gas and efficiency hydrogen fuel generator at 12.99%.
