Now, we mainly engaged in the research and development of hydrogen generation technology by alkaline water electrolysis , hydrogen generation technology by pure water electrolysis, gas purification and drying technology, and based on these scientific research results, PERIC developed and designed a series of products to meet the needs of various applications and occasions, such as Hydrogen (oxygen) generation equipment by alkaline water electrolysis, hydrogen (oxygen) equipment by pure water electrolysis, hydrogen (oxygen) drying and purification equipment, hydrogen-rich water dispensers, and other hydrogen-related products. These products and technologies are not only applied in the traditional industrial field. It is also widely used in new industrial fields such as hydrogen refueling stations, renewable energy utilization conversion, and hydrogen energy infrastructure construction.
