It uses solar photovoltaic power generation and water electrolysis technology to produce high-purity hydrogen, and stores it in high-pressure hydrogen storage tanks, and finally realizes hydrogen filling, providing clean and efficient hydrogen energy for fuel cell vehicles, industrial production, etc. The core advantage of this equipment lies in efficient integration.
