Abstract
Renewable energy development is the focus of attention at this time, using environmentally friendly energy sources and zero emission by utilizing water to make hydrogen through the electrolysis process. The electrode material is selected from materials that have good electrical conductivity and corrosion resistance. Duplex Stainless Steel (DSS) is a material with a combination of two phases, namely austenite and ferrite. The process includes designing tools, manufacturing, and testing the performance of the electrolyzer against the variation in the cross-sectional area with a voltage of 12V and variations in current and electrolytes used are brackish water with a salinity of 8 ppt. The larger the cross-sectional area, the easier the electron transfer that occurs during the electrolysis process, which causes the charge of electrons to react more, then the resulting current will be more significant, this results in a large amount of power generated, while efficiency is inversely proportional to power. Electrode size is also proportional to the current. Electrode 2 inch is more effective than electrode 1.5 inch because, at current 35 A, an efficiency of 93.33% is obtained with the volume of gas produced is 1.9087 Liters.
