Potassium hydroxide (KOH), commonly referred to as Caustic Potash, plays a pivotal role in the operation of alkaline electrolyzers by acting as the electrolyte that splits water into hydrogen and oxygen using electricity. Here’s how it enhances efficiency:
- Electrolyte Role:
- Conduction of Electricity: KOH dissociates completely in water, producing hydroxide ions (OH⁻), which are essential for conducting electricity.
- Enhanced Ionic Conductivity: It ensures efficient ion movement between the anode and cathode, facilitating smooth operation.
- Facilitating Reactions:
- At the Cathode: Provides OH⁻ ions for the hydrogen evolution reaction.
- At the Anode: Replenishes OH⁻ ions consumed in oxygen production.
- Stability:
- Thermal Stability: Performs efficiently at elevated temperatures (50–80°C).
- Chemical Stability: Resists degradation over time, ensuring long-term reliability.
- Corrosion Resistance:
- Maintains a stable alkaline environment, preventing excessive electrode and component corrosion.
- Electrode Compatibility:
- Compatible with nickel-based or other non-precious metal electrodes, avoiding reliance on expensive materials like platinum.
Advantages of Using Chandra KOH:
- Offers higher ionic mobility compared to NaOH.
