SANY Hydrogen Energy Beijing R&D Testing Center

SANY Hydrogen Energy Beijing R&D Testing Center was founded in August 2022, and fully put into operation in April 2023, covering an area of around 500 m² and with a total investment of nearly RMB 6 million yuan.

Adhering to the aim of promoting high-quality development of hydrogen energy equipment, the Center focuses on the development of core technologies for hydrogen production by water electrolysis , and supports the development of advanced, high-performance, and durable electrolyzer products of SANY Hydrogen Energy. The Center has powerful R&D capabilities, thanks to senior industry experts and its development and lab team of full-time researchers with doctoral and master's degrees. The Center currently has two industry-leading development and testing platforms for core components (electrodes, membrane materials, etc.) of AWE hydrogen production equipment and PEM hydrogen production equipment.

 

The platforms are equipped with diverse advanced instruments and equipment for R&D, testing and small-batch trial production, including an industry-leading self-developed testing platform for electrodes/membranes, PEM test bench, hot press, ICP-OES, fluorescence spectrum analyzer, and electrochemical workstation, small-scale electrolyzers, plasma spraying, sandblasting and other equipment, which can simultaneously realize the development of core components, experimental testing for systems, scale-up, small-batch trial production, collaborative emulation, etc., fulfilling the comprehensive testing and technology development for core components of equipment of hydrogen production by water electrolysis. At the same time, for critical parts such as electrodes and membranes, we have independently designed and developed the only testing platform in the industry, considering the current absence of relevant testing standards and significant fluctuations in experimental results of conventional testing methods. We have carried out a large number of research and development experiments and established the details of system testing methods to solve the problems of complex testing and significant fluctuations in results of critical components such as electrodes and membranes, achieving the multi-dimensional assessment of the performance of critical core components and effectively ensuring their advancement and stability.
