   The output pressure of the generator can be adjusted to meet the specific requirements of different applications. The conventional pressure range is sufficient for most laboratory applications, while the high-pressure option allows for use in industrial settings where higher pressures are required.

4. Power Supply: AC 220V/110V, 50~60 Hz, Maximum Power 200W
   The QL-500 is designed to operate on a standard AC power supply with a voltage range of 220V or 110V and a frequency of 50 to 60 Hz. The maximum power consumption is 200 watts, making it an energy-efficient device.

5. Dimensions and Weight: 400×300×710 mm (L×W×H), Weight <15 kg
   The compact dimensions and lightweight design of the QL-500 make it easy to transport and install in various settings. This portability is a significant advantage, especially in laboratory environments where space is often limited.

6. Water Quality Requirements: Water resistivity >1 MΩ·cm
   The generator requires the use of high-quality water with a resistivity greater than 1 megohm-centimeter. This ensures that the electrolysis process is efficient and produces high-purity hydrogen gas.

7. Electrolytic Cell and Electrode Technology: SPE (Solid Polymer Electrolyte) Technology
   The core of the QL-500 is its SPE electrolytic cell, which uses a high-activity zero-gap catalytic electrode formed by integrating a composite catalyst with an ion membrane. This technology allows for efficient electrolysis and high-purity hydrogen production.

Operational Principles

The QL-500 Hydrogen Gas Generator operates on the principle of electrolysis, where an electric current is passed through water to split it into hydrogen and oxygen. Here's a detailed look at the operational principles:

1. Electrolysis of Water:
   When water of the required resistivity is introduced into the anode chamber of the electrolytic cell and an electric current is applied, the water molecules immediately decompose at the anode. This decomposition results in the formation of hydrogen ions (H+) and hydroxyl ions (OH-). The hydroxyl ions then release electrons at the anode, forming oxygen (O2), which is expelled from the anode chamber and carried away with some water into a reservoir. The water in the reservoir can be recycled.

2. Migration of Hydrogen Ions:
   The hydrogen ions, in the form of hydrated ions (H+·XH2O), migrate through the SPE ion membrane under the influence of an electric field. These ions reach the cathode, where they accept electrons and form hydrogen gas (H2).

3. Separation and Drying of Hydrogen Gas:
   The hydrogen gas, which contains a small amount of water vapor, exits the cathode chamber and enters a gas-water separator. Here, most of the water carried over from the electrolytic cell is removed. The hydrogen gas then passes through a dryer to further reduce its moisture content, achieving a purity of over 99.999%.

4. Electrical Control System:
   The QL-500 is equipped with a sophisticated electrical control system that monitors and regulates the electrolysis process. This system ensures stable output pressure and flow rate, and includes automatic protection features to prevent over-pressure and other potential issues.
