Performance Characteristics between Titanium and Stainless Steel Materials as Electrodes on Dry Cell Type HHO Gas Generator

The HHO generator is a device that uses the principle of water electrolysis to produce HHO gas, that is a gas consisting of 2 hydrogen molecules and 1 oxygen molecule. The HHO generator is a technology that can be implemented on an internal combustion engine. In a previous research of a HHO generator with a direct connection system, the electrolyte temperature reached more than 90oC. If the temperature continues to increase, the HHO gas produced will mix with water vapor. The electrode material choice in the HHO generator can affect for electrolyte temperature increase, HHO gas production, HHO generator power, and the efficiency of HHO generator. Therefore, a research be conducted about electrode material and the application of neutral plates to the HHO generator Dry cell type. The electrode material that used as object of research is stainless steel 316 and titanium. Titanium material has a higher thermal conductivity value and lower electrical resistance value than stainless steel 316 material. The parameters measured in this research are electric voltage, electric current, electrolyte temperature in the HHO generator, electrolyte temperature in the reservoir tank, HHO gas temperature, and HHO gas production. While the parameters calculated are electrical power requirements of the HHO generator dry cell type, HHO gas rate production, and efficiency of the HHO generator dry cell type. The results of performance characteristics comparation of HHO generator show that HHO generator with stainless steel 316 electrodes have better performance compared to HHO generator with titanium electrodes.
