- Chloride ions are also prevented from entering the cathode compartment. This ensures that the aqueous sodium hydroxide produced will not be contaminated by sodium chloride.
- There is on hazardous waste as the membrane cell does not use materials like asbestos or mercury.
- Among the three types of cells, the membrane cell the lowest energy requirements. This is because new types of membrane allow the electrodes on opposite sides of the membrane to be very close to each other. This lowers the operating voltage required for electrolysis.
