Abstract
In a direct sea water electrolysis system, deposits on the electrode cause decrease in the performance and increase in electrode damage. To reduce the deposition on the electrode, the modified cells were developed, namely: replaced grating type anodes with plate type ones; reduced the number of anodes from 9 to 8; widened the electrode gap from 2.4 mm to 3.0 mm; and reduced the number of spacers. that maintained the electrode gap, from 27 to 10. The developed cells were installed and tested at a power plant. The modified cells reduced deposition by 36~60%. The current efficiency increased by 15~20%. The electricity consumption reduced by 20%. In each case, the comparisons were between the modified cells and standard cells.
