III. PEM electrolyzer core technology research and development and PEM electrolyzer hydrogen production technology development direction 1. PEM electrolyzer technology research and development The power fluctuation range of wind and solar power hydrogen production is large, and the adverse effects on  hydrogen production equipment  are manifested in a significant reduction in equipment life and the purity of the produced hydrogen. These effects are caused by the attenuation of the main components of the PEM electrolyzer under the condition of wind and solar fluctuating power supply. From a technical perspective, the main challenge facing the PEM electrolyzer is how to improve the working performance and stability through material research and development, assembly process and optimization. Advanced material research and development includescatalytic layer and adhesive materials, corrosion-resistant bipolar plates, organic ion exchange membranes and other directions. The assemb...

II. Basic characteristics of hydrogen production by  PEM water electrolysis  under wind and solar fluctuating power supply Under the fluctuating power supply of wind and solar power, the working parameters of the electrolyzer undergo transient changes, which can cause irreversible damage to  the main components. Exploring the performance characteristics of PEM water electrolysis for hydrogen production under the fluctuating power supply of wind and solar power, the attenuation mechanism and evaluation methods of PEM electrolyzer components are of great value to the research and development of key technologies for PEM electrolyzer components. 1. Wind and solar power fluctuations have a significant impact on electrolytic cells Usually, the input voltage of the electrolytic cell is controlled within a certain range; when the input power of the electrolytic cell fluctuates, the voltage of the electrolytic c...

  Development and application of  proton exchange membrane water electrolysis hydrogen production  technology under wind and solar power fluctuations I The trend of global warming is more obvious. The develo pment of clean energy can alleviate the large amount of greenhouse gas emissions generated by the use of fossil  fuels. Therefore, the development of renewable energy such as wind energy and solar energy is of great significance to the sustainable development of human society. Renewable energy has strong time and space dependence, intermittency, volatility and other characteristics. It also faces the difficulties of reliability and peak and frequency regulation in grid connection. Therefore, converting renewable energy electricity into chemical energy and storing it before using it is more flexible and is an effective way to coordinate the development of source, network and load. Hydrogen has the advantages of being clean and having high quality/energy density. I...

Hydrogen storage technology runs through the hydrogen energy end of the industrial chain to the fuel cell end, and is an important link in controlling the cost of hydrogen.  The storage method of hydrogen is a matter of great concern to people. Currently, the commonly used hydrogen storage technologies mainly include physical hydrogen storage, chemical hydrogen storage and other hydrogen storage. 1.  Physical hydrogen storage Physical hydrogen storage technology refers to the technology of increasing the density of hydrogen by changing the hydrogen storage conditions to achieve hydrogen  storage. This technology is a purely physical process, does not require a hydrogen storage medium, has low cost, is easy to release hydrogen, and has a high hydrogen concentration. It is mainly divided into high-pressure gaseous hydrogen storage and low-temperature liquefied hydrogen storage. 1) High-pressure gaseous hydrogen storage High-pressure gaseous hyd...
