Özet
In this study, a PV-wind hybrid system was proposed as a power source for hydrogen production by alkaline electrolysis and it was examined MATLAB simulation for Adana region. In the alkaline electrolysis cell, lab-made 3D printed cathode substrates were used and its electrocatalytic activity was enhanced via electrodeposition of Ni, Cu and NiCu. The characterization was achieved via scanning electron microscopy, energy-dispersive X-ray, transmission electron microscopy, contact angle measurement and X-Ray diffraction analysis. The electrochemical performance was determined via linear sweep voltammetry, cyclic voltammetry, Tafel polarization measurements, electrochemical impedance spectroscopy, chronoamperometry. Results showed that 3DNiCu electrode exhibited nodular shaped homogeneous surface characteristics and NiCu (111) and (200) crystalline morphology; it also demonstrated lower polarization resistance and higher current density during alkaline electrolysis procedure.
