Hydrogen can be obtained from different sources of raw materials including water. Among many hydrogen production methods, eco-friendly and high purity of hydrogen can be obtained by water electrolysis. However, In terms of sustainability and environmental impact, PEM water electrolysis was considered as most promising techniques for high pure efficient hydrogen production from renewable energy sources and emits only oxygen as byproduct without any carbon emissions. Moreover, the produced hydrogen (H2) and oxygen (O2) directly used for fuel cell and industrial applications. However, overall water splitting resulting in only 4% of global industrial hydrogen being produced by electrolysis of water, mainly due to the economic issues. Nowadays, increased the desire production of green hydrogen has increased the interest on PEM water electrolysis. Thus the considerable research has been completed recently in the development of cost effective electrocatalysts for PEM water electrolysis.
PEM electrolysis has high current densities Compact system design and Quick Response Greater hydrogen production rate with High purity of gases (99.99%) Higher energy efficiency (80-90%) High dynamic operation
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.
