A Systematic Study on Electrolytic Production of Hydrogen Gas by Using Graphite as Electrode

Alkaline water electrolysis is one of the easiest methods for hydrogen production that has the advantage of simplicity. The major challenges in the water electrolysis are the reduce energy consumption, cost and maintenance and to increase reliability, durability and safety. In this regard, the electrolytic production of hydrogen is systematically studied by commercially available graphite electrode at room temperature. The experimental results showed the rate of production of hydrogen gas was significantly affected when the reaction parameters such as effect of electrolyte concentration, temperature, applied voltage and reaction time are varied. From the experimental results, it has been found that graphite is a good choice for the production of maximum hydrogen compared to various other electrodes.
