[0043] As one specific implementation of this utility model, please refer to the following: Figures 1 to 4 The hydrogen storage assembly includes a hydrogen storage cylinder 7 and a hydrogen refueling port 9.

Each row of hydrogen storage cylinders 7 includes two hydrogen storage cylinders 7 arranged at a certain distance.

The hydrogen is then controlled by the inlet valve 20 to enter the pipeline 12 and finally enters the fuel cell to participate in the electrochemical reaction. The current generated by the electrochemical reaction is used by the voltage conversion component 21 (such as a DC / DC converter) to adjust the fuel cell's output voltage to a level suitable for the load requirements, thus achieving a stable and controllable power output. After the system stops working, the hydrogen storage cylinder valve assembly and the inlet valve 20 are closed, and the exhaust valve 19 is opened to discharge excess hydrogen from the pipeline.
