The electrode stream must be vented as it contains small quantities of hydrogen, oxygen
and possibly chlorine gas. (A 2:1 mixture of hydrogen and oxygen gas is produced at a
maximum rate of about 11.4 ml/amp/minute (hydrogen, dry gas at 25 °C, 1.0 atm) Ensure
ventilation maintains the hydrogen gas levels below 4%.
Drains should be designed so that the E-Cell Stack™ cannot drain while in Standby.
