Design of HHO Cell for Green Hydrogen Production
Main Article Content
Abstract
Global warming, driven by scientific and technological progress and rising environmental pollution, has intensified the need for alternative renewable energy sources like hydrogen. This study focused on designing a hydrogen-hydrogen-oxygen (HHO) cell using primary materials, where stainless steel electrodes (10 cm diameter) were coated with carbon nanotubes (CNTs) via electrochemical deposition. The CNTs were synthesized from potato peel waste, demonstrating an eco-friendly approach to nanomaterial production. Structural and morphological analyses of the CNTs were conducted using scanning electron microscopy (SEM), atomic force microscopy (AFM), and X-ray diffraction (XRD), confirming their high surface area and crystalline structure. The research also investigated the impact of electrolyte concentration (KOH) on hydrogen production efficiency. By varying electrolyte parameters and applied current, the study monitored gas output per unit time, revealing a significant increase in H₂ and O₂ flow rates with CNT-coated electrodes. The enhanced performance was attributed to the electrodes' improved conductivity, corrosion resistance, and catalytic activity. These findings highlight the potential of nanotechnology in optimizing renewable energy systems, offering a sustainable solution for green hydrogen production.
