Study the Influences of Both (NaOH and KOH) at Different Electrolyte Concentrations and Times on Hydrogen Production via Electrolysis Process

Namah Saleh, Mousa May.


Abstract
There are various ways to reduce emissions harmful to the environment, including carbon dioxide gas produced from different industries that depend on fossil fuels, which is considered a non-renewable energy sources that will end one day. Recently, there has been a strong focus on finding alternative and renewable ways to produce energy. One of these ways is to use hydrogen as a resource for many applications, including the most important electricity generation. This study deals with the mechanism of hydrogen production through the electrolysis of water, which was represented by the use of a model of the electrolysis cell, through which factors affecting the amount of hydrogen produced such as time, concentration, and electrolyte type. Two different catalysts (electrolyte type) were employed in this study, namely sodium hydroxide NaOH and potassium hydroxide KOH, they were used as electrolysis in order to evaluate the levels of hydrogen production. Experimental results showed that the potassium hydroxide catalyst was better than the sodium hydroxide, due to the activity of potassium ion in the electrolyte medium, which plays an important role in the dissolution process and hydrogen production. The best amount of hydrogen gas production was (140 ml) at 3 minutes, 4 amperes, 10 volts, and a concentration of 5 g/L of KOH. Faradaic efficiency was used to evaluate hydrogen production in both electrolysis mediums. The experimental results showed that the highest Faraday efficiency was 0.179% at a concentration of 5 g/L.

Key words: Hydrogen, Electrolysis, NaOH, KOH, Efficiency.
