How much water will the HOH cell use?
At 100% volumetric efficiency, 1 litre of water produces 2065 litres of HOH gas. Therefore given a gas production rate of 1 litre per minute the electrolyte reservoir holding two litres, then the cell would operate for 4130 minutes or 68 continuous operating hours. 100% volumetric efficiency is not a practical guide as this does not account for evaporation, condensation or less than 100% volumetric efficiency, therefore we recommend that you check your water level every few days if you are driving long distances daily and once every one or two weeks for casual use. In general, depending on the concentration of electrolyte and the total litres per minute will vary how often the water will need to be refilled. At 1 Litre per minute of gas production, 1 litre of water will last for approximately 15 continuous operating hours.
