Core Components of an PEM Electrolyzer

1. Membrane Electrode Assembly (MEA)

The MEA is the heart of PEM electrolyzer stack design. It includes:

  • Catalyst-coated membrane: Usually platinum-based
  • Gas diffusion layers (GDLs): Promote gas flow and distribute water evenly
  • Ionomer: Facilitates proton conductivity

2. Bipolar Plates and Flow Fields

Bipolar plates manage the flow of gases and fluids. Made from coated metals or graphite composites, they:

  • Channel water and gases efficiently
  • Conduct electrical current
  • Provide mechanical support

3. Current Collectors and Gaskets

These ensure secure electrical connections and gas-tight seals, enabling safe and reliable operation.

4. Advanced Materials for Industrial Systems

Newer PEM systems utilize:

  • Corrosion-resistant alloys
  • Enhanced polymer membranes
  • Heat-resistant composites

These improve durability and performance in high-demand industrial settings.

The PEM Electrolyzer Working Principle (Step-by-Step)

1. Water Decomposition at the Anode

Reaction: 2H₂O → O₂ + 4H⁺ + 4e⁻ Water is fed into the anode chamber, where an applied voltage splits it into oxygen gas, protons (H⁺), and electrons.

2. Proton Transport Through the PEM

The PEM membrane selectively allows only protons to pass through to the cathode side, while blocking electrons and gases.

3. Hydrogen Generation at the Cathode

Reaction: 4H⁺ + 4e⁻ → 2H₂ Electrons from the external circuit and protons recombine at the cathode to form high-purity hydrogen gas.

4. Gas Separation and Purification

Integrated gas management systems ensure:

  • Efficient O₂ and H₂ separation
  • Removal of water vapor
  • Delivery of fuel-cell-grade hydrogen

Key Performance Advantages for Industrial Applications

1. Higher Efficiency (75–85%)

HPEM systems outperform many alternatives with low power consumption per Nm³ of H₂.

2. Rapid Load Response

Ideal for fluctuating inputs from solar PV or wind farms, with dynamic ramping and shutoff.

3. Modular and Compact

Space-saving design enables stackable units for scalable deployment—from 100 Nm³/h to multi-MW plants.

4. Minimal Maintenance

No corrosive alkaline liquids and fewer mechanical parts lead to lower OPEX and longer system uptime.

Technical Specifications Buyers Should Evaluate

1. Current Density

Measured in A/cm². Higher densities indicate greater output per cell but may impact lifespan.

2. Hydrogen Production Capacity

Common ranges:

  • Small: 1–10 Nm³/h
  • Medium: 50–100 Nm³/h
  • Large: >500 Nm³/h

3. Stack Lifetime and Degradation

Modern PEM stacks last 60,000–80,000 hours, depending on operating conditions.

4. Balance of Plant (BoP) Requirements

BoP includes:

  • Power electronics
  • Water purification units
  • Thermal management
  • Gas dryers and sensors

Industrial Application Case Studies

1. Renewable Hydrogen Megaprojects

Countries like Germany and Australia are scaling up PEM electrolyzer plants >100 MW to feed green hydrogen pipelines.

Hele Titanium Hydrogen Generator Overview

The HTH Hydrogen Generator is an advanced device utilizing Proton Exchange Membrane (PEM) technology to produce hydrogen with up to 99.9995% purity. This hydrogen finds extensive applications across various fields, serving as carrier gas and fuel gas for Gas Chromatography (GC), collision gas for ICP-MS, feedstock for hydrogenation reactors, fuel for fuel cells, and calibration gas for emission testing equipment. In laboratory settings, it serves as an ideal alternative to conventional gas cylinders, offering an optimal solution for on-site hydrogen generation.

Operating Principle

The HTH Hydrogen Generation System employs platinum catalysts and Proton Exchange Membrane (PEM) technology to decompose deionized water into its constituent elements. The PEM selectively permits the passage of water molecules and positive ions between compartments while functioning as the electrolyte within the cell, eliminating the need for hazardous liquid electrolytes such as concentrated potassium hydroxide. The PEM water electrolysis process involves the straightforward dissociation of pure deionized water (H₂O) into hydrogen (H₂) and oxygen (O₂), which are separated on either side of the membrane.

Upon application of a DC voltage to the electrolyzer, water is transported to the anode (or oxygen electrode) where it undergoes oxidation, producing oxygen, protons, and electrons. Protons (H⁺ ions) traverse the PEM to reach the cathode (or hydrogen electrode), where they combine with electrons from the external circuit and are reduced to form hydrogen gas. The two electrochemical reactions occurring within the cell are as follows:

  1. Anode Reaction (Oxidation):

    Water molecules are oxidized at the anode, generating oxygen gas, protons, and electrons.

  2. Cathode Reaction (Reduction):

    Protons migrating through the PEM combine with electrons at the cathode to produce hydrogen gas.
