     Technical features of H2 generator by water electrolysis. 

• With standardized modular configuration, it can achieve the highest efficiency, versatility and scalability, and is one of the most efficient alkaline electrolyzers.
• The device is designed from scratch to adapt to input fluctuations brought about by renewable energy. Its multifunctional design allows green hydrogen production in many different market segments.
• Mature technology. In the compact electrolyzer, our products use the commercially proven pressurized alkaline technology. The compact modular design increases the number of applications, so it covers a small area
• Special activation to be conducted on cathode in the electrolyzer to ensure the high efficiency of water electrolysis with low power consumption, saving power energy for the customer;
• One number of electrolyzer is composed of multiple stage plates with DC voltage max. 136V, rated DC current 740A to guarantee the H2 gas flow 200NCMH and O2 flow 100NCMH; (the detailed parameters are to be confirmed during the detailed engineering design.)
• All process valves on main processing lines (H2 gas line, O2 gas line and lye circulation lines) are to be imported from Swagelok, USA / Modentic, Taiwan which are found with best quality around world for water electrolysis.
• The material of all process pressure vessels is of 321L SS stainless steel material, to ensure the vessel to fit for the water electrolysis (KOH solution as electrolyte with high operating pressure (1.50MPa-3.0MPa（g） and operating temperature 85 deg.C; );
• The material of process pipe line are of 321L SS stainless steel material, for H2 gas pipeline, O2 gas pipeline and lye circulation pipelines, etc. The pipe size is designed accurately so as to ensure the gas velocity through the pipe lines is restricted within the limit as per international standard code.
• Pneumatic regulating diaphragm valves to be imported from USA are used for the regulating the operating pressure, differential pressure between H2-lye level and O2-lye level and operating temperature.
• All online analyzers including percentage H2 in O2 analyzer, percentage O2 in H2 analyzer（(optional)） are sourced from GE sensing, USA to monitor the gas purity, sending signal for alarm / interlock system in case of any poor purity to be found in the gas.
• Configuration of PLC control and monitoring unit (according to user requirements), an operation-friendly human-machine interface to be provided for the operator to operate and monitor hydrogen generator, including data acquisition and display, historic data record and trench, alarm and interlock, operation priority classification, etc. completely ensure the safety and reliability for hydrogen generator.

(optional) integrated hydrogen generator

(optional) cabinet type hydrogen generator

• All equipment are handed over to the customer in skid-mounted type, to shorten the installation and erection engineering at project site, the customer to do the interconnection between the skid-mounted equipment

    Main product information   

     COMMON INDUSTRY APPLICATIONS OF HYDROGEN.
Hydrogen also has a long history of use in several   industries.
These include:

• Food:

Hydrogen is used to turn unsaturated fats into to saturated oils and fats, including hydrogenated vegetable oils like margarine and butter spreads.

• Metalworking:

Hydrogen is used in multiple applications including metal alloying and iron flashmaking.

• Welding:

Atomic hydrogen welding (AHW) is a type of arc welding which utilizes a hydrogen environment.

• Flat Glass Production:

A mixture of hydrogen and nitrogen is used to prevent oxidation and therefore defects during manufacturing.

• Electronics Manufacturing:

As an efficient reducing and etching agent, hydrogen is used to create semiconductors, LEDs, displays, photovoltaic segments, and other electronics.
Hydrogen is used to create hydrogen peroxide (H2O2). Recently, hydrogen gas has also been studied as a therapeutic gas for a number of different diseases.
