| Popis: | This study aims to determine the maximum concentration of hydrogen gas produced through the electrolysis process of dry cell generators. This research using experimental generator apparatus with Sensor-MQ-8 Arduino and optimizing using Response Surface Method with Design Expert 6. To produce hydrogen gas is done through the method of water electrolysis by decomposing the molecule H2O into hydrogen gas and oxygen gas with the help of direct electric current. Hydrogen gas productivity by electrolysis method applied to DC generators using 4/4 plate electrodes (Cu/Al) as cathodes and NaNO3 solutions as electrolytes. The current and voltage used in this electrolysis process is 0.6 ampere and 2 volts for 1 hour. The optimum condition of hydrogen gas concentration obtained is at NaNO3 1 M concentration and 60 minutes with hydrogen concentration produced as much as 143.393 ppm. The verification result value for hydrogen gas concentration is 144 ppm. |
