DESIGN AND FABRICATION OF A HYDROGEN GENERATOR USING WATER ELECTROLYSIS

This project focuses on the design and fabrication of a hydrogen generator using the water electrolysis process. The main objective is to produce hydrogen–oxygen (HHO) gas as a clean and alternative energy source. In this system, water is mixed with potassium hydroxide (KOH) to improve electrical conductivity and enhance gas production. A 12V DC power supply is used to carry out electrolysis, which splits water into hydrogen and oxygen gases. The setup consists of an electrolysis chamber with inlet and outlet ports and eight stainless steel plates acting as electrodes. For safety, the generated gas is passed through a bubbler and a flashback arrestor to prevent any backflow of flame. The system performance is observed based on gas generation and stability during operation. The results indicate that the addition of KOH improves hydrogen production efficiency. This project demonstrates a simple, low-cost, and effective method for hydrogen generation, which can be used for small-scale applications and as a supplementary fuel in internal combustion engines.
