Process Description of the Pressurized Water Electrolysis System

The hydrogen Generator offered By MOS Techno Engineers is based on Bipolar Pressurized Water Electrolysis Based System. The Hydrogen By Water Electrolyser can be operated at a pressure of from 10 – 32 barg. Each electrolyzer is designed for a capacity 10 % extra of desired final hydrogen flow. The Main equipment of hydrogen generator is electrolyzer, in which, water is decomposed into hydrogen and oxygen through electrolysis, and the equation is : 2H2O >>>> 2 H 2+O 2 <>/p

  • The electrolyzer we use is bipolar pressurized type.
  • The cell of electrolyzer is divided into the anode cell and cathode cell.
  • Hydrogen is generated on the cathode side.
  • Oxygen is generated on the anode side.
  • Electrolyser is filled with electrolyte KOH mixed with DM water (30% KOH).
  • A Rectifier with Transformer is used to change high AC Voltage electricity to low AC voltage and then through rectifying by the rectifier to become DC power.
  • The positive pole of DC power is connected to the anode of the electrolyzer, the cathode of electrolyzer is connected to the negative pole

  • The positive pole of DC power is connected to the anode of the electrolyzer, the cathode of electrolyzer is connected to the negative pole

Cathodic reaction is 4H 2O+4e >>>> 2H 2+4OH- Anodic reaction is 4OH ­­- >>>> O 2+2HH2O+4e

  • Once the DC current is passed in the electrolyzer while the electrolyte is being circulated the hydrogen and Oxygen are generated and are sent hydrogen and oxygen separators.
  • In the Separators, the hydrogen and oxygen are separated with electrolyte due to gravity and the electrolyte come down.
  • The pressure in the system is raised due to accumulated gas and is maintained at a set pressure by means of regulating valve.
  • The electrolyte at the bottom of hydrogen and oxygen separators by gravity comes back and is pumped back to electrolyzer after filtering and cooling, to complete the process cycle.
  • While THe hydrogen gas is generated and is collected for further use, the Oxygen generated can also be collected for use separately or allowed to be vented.
  • The DM Water (pressurized) is continuously fed to the Gas Separation Skid enabling makeup of Dm water used while generation.
  • The Hydrogen Generated from electrolyzer Is of 99.9 % pure and can be used for most of the applications.
  • For higher purity, Hydrogen Purification is provided by which Hydrogen of 99.999% and a Dew Point of (-) 70°C can be achieved.
  • Our Hydrogen Plant can be designed for a pressure of a minimum of 10 barg to a maximum of 30 barg. In case a higher pressure is required, an oil-free diaphragm type hydrogen booster can be provided.
