Stack for Pem Water Electrolysis

he team and technologies of Shanghai H-Ray S&T company is originated from Shanghai Advanced Research Institute, Chinese Academy of Sciences. We focuses on research and development of PEM water electrolysis technologies more than twenty years. Shanghai H-Ray S&T company produces its own PEM membrane electrode assembly (MEA), bipolar plates and coatings, fluid-dynamically optimized gas diffusion layer(GDL), reliable sealing and high consistency assembly of stacks as these are the core know-how of an electrolysis system. Ryzer PEM electrolyzer Portfolios are in-house developed, manufactured and tested product according to ISO and ASME standard, CE mark, DEKRA , TUV certification.  

Ryzer® portfolios are designed for operation in any industrial environment taking into account every aspect for long-term economic viability. The entire system is designed for typical industrial lifetimes (as standard: 20 years for mechanical components), 24/7 operation, serviceability and remote monitoring. according to ISO22734, PED, ATEX,CE

The PEM stack is able to operate more than 80,000 hours or 10 years, whichever comes first, based on continuous full-load operation. Depending on the business case and the commercial calculations the stacks can be replaced at any time. The process part as well as the entire PEM electrolysis system ((System and BOP) is designed for typical industrial lifetimes > 20 years.



Product advantage:2. Excellent mass and heat transfer chemical process performance of bipolar multi-element electrolytic cell structure 
3. No chemicals are added, corrosion resistance, passivation resistance and other superior performance of bipolar multi-element electrolytic cell material selection 
4. Real-time monitoring System ensuring uninterrupted operation, such as water shortage, overpressure, waterproof, explosion-proof ,smart automatic protection system ensuring higher safety
5. Electrolysis of pure water (eliminating alkali addition) for hydrogen production, no corrosion, no pollution, high hydrogen purity 
6. Lower voltage and higher current density operation, low internal resistance of electrolyzer without heating, long-life operation and replacement free, higher hydrogen purity.
7. Sufficient H2 production based on short startup time and fast pressure boost (3-5 minutes) 
8. Stabilization pressure and steady flow output of Hydrogen, automatic monitoring and tracking system to the change of power consumption.
9. Real-time monitoring System ensuring uninterrupted operation, such as water shortage, overpressure, waterproof, explosion-proof ,smart automatic protection system ensuring higher safety
10, lower noise 
11, lower power consumption, high electrolysis efficiency 
12. skid-mounted integration system with full BOP in one container. "plug and play" concept reduce site activity and time.
