However, the height of the vehicle bottom is too low, and it is very inconvenient to replace the gas cylinder. In addition, the replacement of the gas cylinder is not efficient and convenient, and the use effect is poor. Therefore, the market urgently needs to develop a built-in commuter bus hydrogen replacement system to help people solve the existing problems. Summary of the invention
