Application Of Graphite Rods in Electrolyzed Water

The process in which water (H2O) is electrolyzed by direct current to generate hydrogen and oxygen is called electrolyzed water. When current passes through water (H2O), hydrogen gas (H2) is formed by reducing water at the cathode, and oxygen gas (O2) is formed by oxidizing water at the graphite anode. Hydrogen is produced approximately twice as much as oxygen. Water electrolysis is the next generation hydrogen fuel production method to replace hydrogen production by steam reforming.
Conditions for forming an electrolytic cell: (1) DC power supply. (2) Two electrodes. The electrode connected to the positive pole of the power supply is called graphite anode, and the electrode connected to the negative pole of the power supply is called cathode (3) Electrolyte solution or molten electrolyte.
The ions in water (H2O) are always in a disorderly movement, and after the direct current is applied, the ions move in a directional manner. An oxidation reaction occurs at the anode and a reduction reaction occurs at the cathode. Cations move to the cathode, get electrons at the cathode, and are reduced; anions move to the anode, lose electrons at the graphite anode, and are oxidized. In the process of water electrolysis, OH loses electrons at the graphite anode and is oxidized to oxygen and released; H gets electrons at the cathode and is reduced to hydrogen and released. The resulting oxygen and hydrogen.
