Problems solved by technology

However, the built-in solar vacuum heat collector is filled with Cu@C catalyst as a hydrogen production reaction tube. The internal structure and processing technology are very complicated, which is not conducive to later maintenance and replacement of the catalyst, and the service life is short.
Moreover, the glass used in the solar vacuum heat collecting tube is easy to be damaged due to changes in cold and hot temperatures or impact, which is more dangerous.
In addition, due to the use of the gravity of the closed high-level tank to ensure the automatic feeding of methanol water, in order to maintain this gravity, the high-level tank needs to be fixed at a higher position, so the requirements for the size and installation location of the entire hydrogen production device are higher. , and increased risk
