Hydrogen – Oxygen Units

KERN builds hydrogen and oxygen production units

The need for the availability of hydrogen ‘in situ’ has led us to develop bipolar electrolyzers capable of producing hydrogen and oxygen by electrolysis of water.



The principal systems of these plants are:

  • Rectifying unit and water electrolysis
  • Hydrogen/Oxygen low pressure storage
  • Hydrogen/Oxygen purification
  • Hydrogen/Oxygen high pressure storage

Main technical specifications:

  • Hydrogen capacity in the range of 1 to 200 nmc/h de capacidad: de 1 a Nm3/h
  • Hydrogen/oxygen production ratio (2:1)
  • Electrolyzers: easy to maintain, reliable and safe (tested in environments where safety and reliability requirements are very high - electrical stations, ...)
  • High level of gas purity
