Performance of Distilled Water Electrolysis with Adding of Sodium Bicarbonate as Catalytic

Abstract:

Water is a chemical compound with chemical formula H₂O. By the electrolysis proses, water can be split constituent elements, namely hydrogen (H₂) and oxygen (O₂). In this study, an electrolyze system used six pieces of electrodes which made from 304L SS for electrolysis process for both of distilled water and adding catalyst NaHCO3 (Sodium Bicarbonate) on distilled water. The results indicated that electrolysis process on distilled water consumed power of 353.52 Watts to produce Brown’s gas of 0.00123 l/s. Whenever, NaHCO3 was added into distilled water with the mass fraction of 1.33% consumed power decrease of 27.89 Watts and Browns gas was produced 0.0017 l/s. The efficiency of distilled water had the greatest efficiency only 5.53% by using current of 2 Ampere and power reached 31.043Watts. While the addition of catalysts had the greatest efficiency reached 40.29% in the use of mass fraction of catalyst 1.5%, 6 Ampere currents and power of 19.829 Watts.
