Understanding Electrolysis
Explanation of the Electrolysis Process
At the heart of the hydrogen production revolution lies the intricate process of electrolysis. Electrolysis is an electrochemical reaction in which an electric current is passed through a water solution, causing the water molecules to dissociate into hydrogen and oxygen gases. The basic equation for this process is:
2H₂O(l) → 2H₂(g) + O₂(g)
Within an electrolyzer, water molecules are split into their constituent ions: positively charged hydrogen ions (protons) and negatively charged hydroxide ions. As an electric current passes through the electrolyte, hydrogen ions migrate towards the cathode (negative electrode), while hydroxide ions move towards the anode (positive electrode). At the cathode, hydrogen ions are reduced to form hydrogen gas, while at the anode, hydroxide ions are oxidized to release oxygen gas. The result is the separation of water into its two elemental components.
