Product Description

The modular electrolyzer with bipolar pressurization technology adopts special design and patented materials, so the electrolyzer will not leak during operation, has long service life and no need any maintenance;

In the compact electrolyzer, non asbestos patented material is used as diaphragm, pure nickel mesh is used as cathode and anode, patented material is used as sealing gasket, carbon steel and pure nickel coating are used as bipolar plate, the precise design of sealing structure, the electrolyzer can enjoy at least five years of free maintenance, and it's good for the environment..

Special activation treatment is carried out on the cathode of the electrolyzer to ensure the high water electrolysis efficiency with low power consumption ，and save electric energy for customers;

An electrolytic cell consists of 68 cells with maximum DC voltage. 136v, rated DC current 740A, ensure the H2 gas flow of 20ncmh and O2 gas flow of 10ncmh; (detailed parameters should be confirmed in the process of detailed engineering design.)

Chemical KOH (25% to 30%) is used as an additive in the electrolyte to increase conductivity, but does not consume chemicals during normal operation, so there is no need to supplement the electrolyte after the first start-up.

Company Indroduction

We have a professional after-sales service team for hydrogen generation system with rich experience in hydrogen machine maintenance.According to the running state and environment of hydrogen production machine , we will help you optimize and upgrade the system, design plans suitable for the operation of the machine, improve the monitoring and detection for DCS and PLC, enhance the running safety and using cycle of hydrogen production equipment, so that reduce system failure caused by peripheral equipment (hydrogen compressor, dryer, PLC controller, etc.) and equipment failure or accident caused by personnel operation mistakes.

In view of the system shutdown caused by the fault of individual components for most users (such as system pressure imbalance and inaccurate measurement of the analyzer caused by the fault of pressure transmitter and ), we have stable detection methods and equipment maintenance plans for hydrogen production machine.
