What is the purity of hydrogen at the outlet?
The hydrogen outlet contains more than 99,9% pure hydrogen (H₂) at less than 55°C (depending on the room temperature). There are small amounts of water (~1000ppm H₂O) and even smaller amounts of oxygen (O₂). Those amounts can be further decreased

The hydrogen outlet contains more than 99,9% pure hydrogen (H₂) at less than 55°C (depending on the room temperature). There are small amounts of water (~1000ppm H₂O) and even smaller amounts of oxygen (O₂). Those amounts can be further decreased with a hydrogen dryer to reach up to 99,999% pure hydrogen. Please see the datasheet for more information. The electrolyser or the dryer itself does not have any sensors to measure the amounts of oxygen or water contamination. To produce a highly purified hydrogen right after the start-up, the electrolyser purges the first few litres of hydrogen via the H₂ vent line.
