XYH-500 High Purity Hydrogen Generator

Product Introduction
The XYH-500 High Purity Hydrogen Generator is designed to provide a continuous supply of high-purity hydrogen for laboratory analytical instruments and related applications. It delivers hydrogen purity of up to 99.999% and an output flow range of 0–500 mL/min.
The generator features straightforward operation, overpressure protection, a liquid-return prevention device, and a dual-purification system. After the initial alkaline solution preparation, users only need to add distilled water as required and switch on the instrument to generate hydrogen.
With its compact footprint and net weight below 11 kg, the XYH-500 is suitable for laboratories requiring a convenient on-site hydrogen supply.

Performance Features
• High hydrogen purity: Provides hydrogen with a specified purity of 99.999%.
• Convenient operation: Requires distilled water replenishment during routine use after initial preparation.
• Stable gas output: Designed to maintain stable flow and hydrogen purity during continuous operation.
• Overpressure protection: Incorporates a pneumatic system protection device to help prevent excessive pressure.
• Liquid-return prevention: A dedicated device helps prevent liquid from flowing back into connected instruments.
• Dual purification: Uses a two-stage purification system to support high-purity hydrogen delivery.
• Stainless steel gas lines: Gas-contact tubing is made of stainless steel, with electrolytic polishing and ultrasonic cleaning.
• Compact design: Measures 320 × 185 × 350 mm and weighs less than 11 kg.

Working Principle
The XYH-500 generates hydrogen through electrolysis using an alkaline electrolyte. When electrical power is applied, water is decomposed to produce hydrogen, which is then processed through the instrument's purification system before being delivered to the connected equipment.
The dual-purification system helps remove impurities, while the pressure protection and liquid-return prevention devices support safer, more stable gas delivery. Distilled water is used for routine replenishment according to the manufacturer's instructions.

Routine Supply	Distilled water replenishment and electrical power	Cylinder replacement or refill
Footprint	Compact benchtop design	Requires cylinder storage space
Pressure Control	Built-in pressure protection; output up to 0.4 MPa	Depends on cylinder regulator
Gas Purification	Integrated dual-purification system	Depends on supplied gas grade and external purification
Operational Considerations	Requires maintenance and correct water quality	Requires cylinder handling and storage procedures

Frequently Asked Questions
Q1: What is the hydrogen purity of the XYH-500?
The specified hydrogen purity is 99.999%.
Q2: What is the maximum hydrogen output flow?
The rated output flow range is 0–500 mL/min.
Q3: What is the output pressure?
The specified pressure range is 0–0.4 MPa, with a factory setting of 0.3 MPa.
Q4: What type of water should be used?
