Decomposition voltage construction

These electrolyzers are operated at about 80°C, as opposed to the 95°C common in the industry. This lower temperature allows the use of vinyl ester resins and other plastics for cell construction. Moreover, the Dow diaphragm cell is optimized for low current density ( 0.5 kA/m2 ). It consumes less electrical energy per unit of production than others in the industry. The cell voltage at low current density is only 300—400 mV above the thermodynamic decomposition voltage. Dow does not license its diaphragm cell technology and operating data for these cells are not available in the open literature.
