## Abstract

Oxyhydrogen (HHO) gas, which is created when water is electrolyzed using a dry cell electrolyzer, is becoming more and more popular as a new energy source because of its improved combustion properties. The creation of HHO wet cell is the primary goal of the current study in order to maximize gas flow rate and improve electrolyzer efficiency compared to dry cell. An inexpensive electrolyzer made of local obtainable parts was used to create HHO. Stainless steel 316L electrodes having a surface area of 136.5 cm2 and 4 mm distance between plates were used to generate HHO gas. Various concentrations of KOH and NaOH electrolytes were used. The rate of HHO generation was influenced by the electrolyte ratio, operation time, cell connection, electric current, electrolyte temperature, and voltage. Different plate arrangements were looked at. It had been discovered that raising the voltage, electrolyte temperature, electrolyte concentration, and applied current all contributed to higher gas generation. At 90 min. operation time, the wet cell showed continuous output peak values of 975, 1160, 1325, and 1375 ml/min at 5, 10, 15, and 20 g/L NaOH, respectively, along with supply currents of 17.8, 23.5, 26, and 27 A. At 5, 10, 15, and 20 g/L catalyst percentage, the temperatures were increased to 35, 44, 50, and 58°C, respectively. With a production efficiency of 69.3%, the HHO wet cell generated 1160 ml per minute at 18 amps and 10 g/litre of NaOH. Wet cell electrolyzers overheating has drawback for practical applications due to higher current supply about dry cell.
