The Effect of NaHCO sub(3) as Catalyst via Electrolysis

Renewable energy is a kind of energy that comes 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 sub( 3) via electrolysis was studied. Stainless steel is chosen to be as the electrode and different concentrations of NaHCO sub( 3) are used as alkaline solutions in electrolysis system. The rates of hydrogen gas produced using different concentration of NaHCO sub( 3) and pH value of every sample were measured. The experimental results that the performance of water electrolysis was highly affected by NaHCO sub( 3), the rate of hydrogen gas showed that 0.4 M of NaHCO sub( 3) and 65 ml/min at pH 8.2 are the best amount.
