This study is to evaluate the surface of AISI 316 as an electrode material for water electrolysis under various potassium hydroxide (KOH) electrolyte concentrations. In the experimental method, AIS316 electrode and KOH solution put into the water electrolysis system. The electrolysis system was combined with the hybrid car engine system that consumed a combination of hydrogen and gasoline as the fuel source. KOH solution concentration was varied from 0 to 0.53M, which was then used to evaluate the surface of AISI 316 electrode as well as hybrid car performances. The experimental results showed that electrolyte solution concentration is an important parameter to maintain high-efficiency hydrogen generation. The more KOH added it gave benefits for creating the more hydrogen gas. However, it brought problems in the electrode surface corrosion. The optimum condition to get more hydrogen gas but with less corrosion damage was obtained when performing the process with 0.40 M of KOH. Indeed, the result also found that the more hydrogen gas being produced has a direct correlation to the reduction of fuel consumption and exhaust gas emission (e.g., CO 2 , CO, and NO x ).[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]AISI 316,Electrolysis systems,Electrolyte concentration,Electrolyte solutions,Experimental methods,Fuel savings,Hydrogen generations,Water electrolysis[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]AISI 316,Corrosion resistance,Exhaust gas emission reduction,Fuel savings,Potassium hydroxide[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]We gratefully acknowledge to Directorate of Research and Community Service, Ministry of Research, Technology, and Higher Education, Republic of Indonesia (RISTEK-DIKTI) for financial supporting through the grant of Penelitian Terapan Unggulan Perguruan Tinggi and Penelitian Unggulan Strategis Nasional.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
