As the demand for cleaner energy accelerates globally, Bipolar Electrolysers — based on Proton Exchange Membrane (PEM) technology — are emerging as the cutting-edge solution for dynamic, high-purity hydrogen production. ORAIPL, a pioneering PEM Electrolyser Manufacturer in India, delivers advanced PEM systems engineered for the most demanding applications in mobility, grid integration, and renewable energy.
As a global leader in Green Hydrogen technology, ORAIPL manufactures high-capacity PEM Electrolysers (60-100 GW) to support industrial hydrogen production, mobility pilot projects, and hydrogen shipping applications.
What is Bipolar Electrolysis?
Bipolar Electrolysis refers to a system where electrolytic cells are stacked, with each pair sharing a conductive plate that acts as both the anode for one cell and the cathode for the next. In PEM Electrolysers, this stacked design minimizes resistance and maximizes efficiency.
The Proton Exchange Membrane acts as both the separator and the electrolyte, allowing only protons (H⁺) to pass while blocking gases and electrons.
How PEM Electrolysers Work
Electrochemical Reactions in a PEM Electrolyser:
-
At the Anode (+):
H₂O → ½O₂ + 2H⁺ + 2e⁻ -
At the Cathode (−):
2H⁺ + 2e⁻ → H₂
The PEM membrane ensures that hydrogen and oxygen gases are separated, while protons migrate through the membrane to form high-purity hydrogen gas on the cathode side.
Key Fact: 1 liter of water can produce 111 grams of hydrogen!

Efficiency & Cost of Electrolysis
Electrolyser efficiency is measured in kilowatt-hours (kWh) per kg of hydrogen produced. According to the US Department of Energy (DOE), ongoing advancements in electrolyser technology and reductions in renewable energy costs are making green hydrogen production more affordable.
Efficiency Breakdown
| Electrolyser Type | Efficiency (%) | Energy Requirement (kWh/kg H₂) |
|---|---|---|
| Alkaline Electrolyser | 65-70% | 50-55 kWh/kg H₂ |
| PEM Electrolyser | 70-80% | 45-50 kWh/kg H₂ |
| SOEC Electrolyser | 80-85% | 40-45 kWh/kg H₂ |
Cost Trends of Electrolysis
-
Current Green Hydrogen Production Cost: $3-6/kg
-
Expected Cost by 2030: $1-2/kg (as projected by the Hydrogen Council, due to falling renewable energy costs & electrolyser advancements)
With ongoing R&D and economies of scale, electrolysis is becoming cheaper and more efficient, making green hydrogen competitive with fossil fuels.
