2. Technology Implementation and Working Principle
How Pure Water Electrolysis Works
Pure water electrolysis uses deionized water and electricity to produce hydrogen and oxygen gases:
2H₂O(l) → 2H₂(g) + O₂(g)
This clean process is powered by renewable electricity, making it a sustainable method for H2 generation.
Key Technological Components
2.1 Electrode Materials
Chinese manufacturers use advanced electrode coatings (e.g., platinum-iridium) to reduce resistance and improve gas output.
2.2 Membrane Technology
Many systems use PEM (Proton Exchange Membrane), known for high purity H2 production and compact system design.
2.3 System Architecture
Components typically include:
- Water purification systems
- Electrolyzer stacks
- H2/O2 gas separators
- Control units
Advantages Over Other Methods
- Cleaner output: No KOH or electrolytic additives.
- Simpler maintenance: Less corrosion.
- Higher purity: Ideal for sensitive applications like fuel cells.
