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

摘要

Water is a chemical compound with chemical formula H_2O. By the electrolysis proses, water can be split constituent elements, namely hydrogen (H_2) and oxygen (O_2). 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 NaHCO_3 (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, NaHCO_3 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.
