Proton exchange membrane (PEM) water electrolyzer (PEMWE) is used to obtain a high amount of hydrogen cleanly from water. However, to make PEMWE common in everyday life, their cost must be reduced, and the performance of these systems must be increased. Thus, alternative materials should be developed to obtain low-cost PEMWE systems. In this study, stainless steel 316L (SS316L) is used as gas diffusion electrode (GDE) materials. The selective laser melting (SLM) method is selected to produce the SS316L electrode. To enhance to SS316L electrodes' corrosion resistance and kinetic activity, SS316L electrodes are coated with Pt different thickness values using electron beam evaporation method (EBM) with a Cr interlayer film. Electrochemical properties of SS316L electrodes have been investigated by cyclic voltammetry (CV), linear sweep voltammetry (LSV), and electrochemical impedance spectroscopy (EIS) techniques. Durability of SS316L electrodes have been conducted by Tafel and chronoamperometry (CA) techniques. The surface morphologies of SS316L electrodes have been characterized by field emission scanning electron microscopy (FE-SEM), energy dispersive X-ray analysis (EDX), X-ray diffractometers (XRD), and X-ray fluorescence (XRF) analysis. As a result, electrochemical performance, kinetic activity, and corrosion resistance of the electrodes are enhanced significantly with Pt-Cr material by EBM coating.
