If you aren’t familiar with this new renewable source for power generation, you don’t have to worry.

We are here with a helpful guide that will give you enough information to maybe answer your fundamental questions concerning hydrogen generators.

Let’s get on board to discuss this new hydrogen technology that will be the ultimate power source for the coming generations.

Let’s move with us by clicking here if you want to know about the different types of generators.

Entering To The New Era Of Hydrogen Generators:

The Hydrogen generator is a module that generates hydrogen gas as a fuel in the presence of water during Electrolysis.

The hydrogen produced is collected and utilized as a renewable power source for electricity generation. 

For power generation, hydrogen fuel cells take the hydrogen gas and oxygen and produce electricity by electrochemical reaction. Finally, you get electricity, water, and a small amount of heat. 

With advancements in technology, you can now produce electricity using a renewable source of hydrogen.

Why Hydrogen Is Preferred-Things To Notice?

Hydrogen is an invisible, non-toxic, odorless, abundant element in nature and high amounts in combination with oxygen (water).

It is among the eco-friendly power source generators that do not harm the environment.

The best thing about hydrogen gas is that even fossil fuels will exhaust one day, but the hydrogen will still be available until the world lasts. So, it’s the best way to secure the energy demand of future generations. 

What makes it special is it is made through Electrolysis using water and converted back to water when used as a fuel for power generation. Isn’t that amazing?

These features make it the best source to opt for eco-friendly power generation.

How Does A Hydrogen Generator Work?

The procedure is as follows.

  • Electrolysis:

Hydrogen generators work by the process called the Electrolysis of water. The hydrogen generator is the purest form, comprising about 99.999% purity.

Parts And Requirements:

  • Electrolyzed cell 
  • Dual Electrodes (anode and cathode)
  • Ion exchange membrane
  • Platinum catalyst 
  • Water 
  • Voltage supplier


Setting The Module: 

The module works by supplying water as a raw source for hydrogen generation; then, a continuous voltage is applied. 

Voltage Supply:

The voltage flows to the dual-installed electrodes on both sides of the electrolyzed cell.

Reaction At Anode:

When voltage passes through a positively charged anode, the water molecule loses 02 of its electrons, resulting in the formation of 04 hydrogen ions and an oxygen molecule. 

Reaction at Anode= 2H2O+voltage (loss of e-)   O2 + 4 H+

Ion Exchange Membrane:

The hydrogen ions produced are permeable to the ion exchange membrane and quickly pass through it, while the oxygen molecule flows back into the atmosphere. 

Reaction At Cathode:

The hydrogen atoms get attracted by the cathode (negatively charged), reducing them to hydrogen molecules in the presence of four electrons. 

Reaction at Cathode= 4H+ + 4e- (gain of e-) 2H2

Resultant Hydrogen Gas:

After the reaction at the cathode, you get the purest hydrogen gas, which can be further stored and utilized as fuel for electricity generation. 

  • Proton Exchange Membrane Fuel Cell (Electricity Generation) 

How is hydrogen utilized for electricity generation, and how will it be the power solution for future generations? You might be thinking all these, but we will solve your query by describing a quick process in a second. 

For powering your homes, you can opt for Proton Exchange Membrane Fuel Cell or a Polymer Electrolyte Membrane fuel cell that has the power to generate electricity using hydrogen gas as a raw material.

The resultant electricity is used instead of a standard power backup because the use of hydrogen makes it the best eco-friendly source.


  • Electrodes (porous carbon)
  • Platinum catalyst (reaction speedup)
  • Hydrogen gas (fuel)
  • Oxygen (oxidizer)


Setting The Module:

The module works by supplying hydrogen gas to the anode.

Reaction At Anode:

At the anode, the Hydrogen molecule gets oxidized to hydrogen ions with the liberation of electrons by hydrogen. 

Ion Exchange Membrane:

The hydrogen ions are permeable to the membrane and quickly pass out and reach the cathode, while the electrons simultaneously flow through the external circuit to the cathode.

Reaction At Cathode:

The oxygen molecule gets reduced at the cathode by the hydrogen ions and electrons forming water as a by-product. 

The Electricity Generation:

The current is produced and travels in the opposite direction when the electron flow occurs between the anode and the cathode during the chemical reactions in the cell.

The electrical current produced can be opted for work in the external circuit.

Hydrogen can virtually power anything, including your entire house, with a clean, abundant power source.

Uses Of Hydrogen Generators:

  • Stores high amounts of the produced oxygen 
  • Utilize hydrogen as a fuel for electricity, power, and heat generation
  • In laboratories for gas chromatograph (GC)
