Zero Gap Modification
Many existing membrane electrolyzer are finite gap. ANCAN can modify the electrodes to zero gap.

ANCAN Technology Innovation to Stay Ahead of Production2
Benefit of Zero Gap Modification --- Comparing with Finite Gap1 Lower cell voltage --- Saving of > 140 kWh/t 100% NaOH2 Can increase operating current, equivalent to >10% of
production increase3 Reduce membrane vibration, prolong membrane life
span4 More even current distribution, safer operating condition
Requirement ---Zero Gap Modification ---Cell Voltage Monitoring ---Differential Pressure Control and Protection ---Operation Skill

ANCAN Technology Innovation to Stay Ahead of Production2
ANCAN Coating - Anode
Membrane Electrolyzer Anode Coating：
◆ Excellent electrochemical characteristics and longer life.
◆ Lower chlorine evolution potential, higher anode efficiency
◆ Good resistant properties against deposit of anolyte contaminants
Anode Coating Magnified
ANCAN Technology Innovation to Stay Ahead of Production2
Membrane Electrolyzer Cathode Coating ◆Stable and good electrolysis property and can resist some degree of polarity reversal.
◆ Lower Electric potential ◆ Good resistant properties against
deposit of catholyte contaminants
