Abstract. This research focused on the synthesis and study the iron oxide formation on stainless steel 304L (SS304L) by anodizing method for hydrogen production. The study is carried out in AC anodizing, optimization of AC anodizing parameters such as such as anodizing voltage, concentration of ammonium fluoride (NH4F), anodizing time, and the temperature of the electrolyte solution by using L9 Taguchi orthogonal arrays with including ANOM analysis and repetition of the experiment for the optimum parameters and lastly is the hydrogen application. The anodizing electrolyte used are ethylene glycol solution with ammonium fluoride and distilled water. Surface morphology of the anodized films were characterized using field emission scanning electron microscopy (FESEM) and transmission electron microscopy (TEM). The optimization via the Taguchi method identified the best combination of parameters such as 30 V of anodizing voltage, 0.3 M of NH4F concentration, 15 ℃ of electrolyte temperature and 20 minutes of anodizing time, enhancing the electrocatalytic activity for the hydrogen evolution reaction (HER). Under optimal conditions, the AC anodized SS304L exhibited significantly improved performance, with increased stability and efficiency in water splitting applications, compared to as-received specimen. These findings suggest that by carefully controlling the anodizing parameters, it is possible to produce AC anodized SS304L with superior electrocatalytic properties, making it a viable and cost-effective option for renewable hydrogen production.
