Hydrogen Generators and its Applications


Hydrogen (Symbol ‘H’) is the lightest chemical element and gas without color, taste, and smell.  It is flammable in a concentration of 4 to 94%. ‘H’ gas is completely safe for humans and the environment and it is safe for all internal combustion engines as well.

So what are Hydrogen Generators?

Hydrogen generators are systems that are capable of producing Hydrogen from various sources of rich hydrogen such as water, ammonia, methanol, natural gas etc.


Hydrogen Generators that split water into hydrogen and oxygen use a process known as water electrolysis. As water is a poor conductor of electricity, typically a catalyst is required in order to facilitate the split. Traditionally alkaline mediums are used for catalysis and use chemicals such as potassium hydroxide (KOH) or sodium hydroxide (NaOH). More advanced water electrolysis generators such as those supplied by MVS principals – NEL Proton PEM hydrogen generators use a proton exchange membrane (PEM cell was originally developed by NASA and is greatly used in the laboratory as well as industrial applications) to produce hydrogen gas from water. In other terms, the ‘H’ generators are a device in which electrochemical reaction (Electrolysis of water) takes place. It is the most famous and long used method of obtaining ‘H’ and ‘O’ gas.


MVS Engineering has supplied NEL Proton PEM Hydrogen generators for a variety of different applications including:

  • Rubber chemical processes that require hydrogen during processes
  • Chemical Vapour Deposition (CVD) processes for crystal growth
  • Oil & Gas research and development for hydrotreatment and hydrocracking
  • Power plant turbine generator cooling
  • Powder metallurgy processes such as sintering
  • Metallurgical processes such as annealing
  • Glass manufacturing
  • Float glass manufacturing
  • High-Tech glass component manufacturing such as X-Ray tubes
