Abstract

Electrolysis is an easy method for splitting water into hydrogen and oxygen. Various sized and  capacity electrolysers are under use to produce hydrogen in large scale all around the world.  However, for a simple demonstrative experiments at home, 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 locally available graphite electrode at room temperature. The  experimental results showed that the rate of production of hydrogen gas was significantly affected  when the reaction parameters such as effect of electrolyte concentration, temperature, applied  voltage and electrode type are varied. From the experimental results, it has been found that  hydrogen production boosts with temperature and graphite is a good choice for the production of  maximum hydrogen compared to various other electrodes.
