The effect of NaHCO3 as catalyst via electrolysis

Abstract

Renewable energy is energy are come from natural sources like water, sunlight, wind and so on. Water electrolysis is currently the most dominant technology used for hydrogen production from renewable sources because of high energy conversion efficiency. In this present work, the effect of NaHCO 3 via electrolysis were study. Stainless steel is chosen to be as the electrode and different concentration of NaHCO3 are used as alkaline solutions in electrolysis system. The rate of hydrogen gas produced using different concentration of NaHCO3 and pH value of every sample were measured. The experimental results that the performance of water electrolysis highly effected by NaHCO3, the rate of hydrogen gas shown that 0.4 M of NaHCO3 are the best amount is 65ml/min at pH 8.2.
