PURE-WATER SPE TECHNOLOGY

A compact hydrogen generation solution using solid polymer electrolyte (SPE) technology for high-purity hydrogen output without alkaline solution.

01

Product Overview

High-purity hydrogen generation from pure water

The PGH series hydrogen generator adopts solid polymer electrolyte (SPE) hydrogen production technology, using pure water as the electrolyte. High-purity hydrogen is generated by electrolysis through titanium metal electrodes, with a relative oxygen content of less than 0.1 ppm. The hydrogen is then separated from water, dried and purified before output.

Its core advantages include stable pressure with fluctuation below 0.001 MPa, on-demand hydrogen production, and no alkaline solution addition. The system is suitable for laboratory, medical and industrial applications.

High-Purity Hydrogen

Relative oxygen content < 0.1 ppm after gas-water separation, drying and purification.

Stable Output Pressure

Pressure fluctuation is maintained below 0.001 MPa.

On-Demand Production

Hydrogen is generated as required, supporting continuous or intermittent operation.

Low-Maintenance Water System

Uses pure water or twice-distilled water; no alkaline solution is required.

Product Features

Intelligent control, low maintenance and built-in protection

1

Intelligent Control System

• One-touch operation: press the power switch to start hydrogen production; supports continuous or intermittent operation.
• Accurate monitoring: high-brightness LED digital display shows real-time flow rate with ±1 mL accuracy and pressure values.
• Pressure self-adaptation: when pressure reaches the preset value (for example, 0.4 MPa), the system automatically adjusts gas production to keep output pressure fluctuation ≤ 0.001 MPa.

2

Low-Maintenance Design

• Simplified maintenance: only regular refill of pure water or twice-distilled water is required.

3

Safety Protection

• Anti-backflow design: a built-in anti-backflow device helps prevent liquid backflow.
• Multiple protections: automatic shutdown for overpressure or low water level to protect the equipment and operator.
