As shown in fig. 1, in the present embodiment, a power interface 431 is disposed on the housing 10, and in order to further improve the stability and reliability of the power generation device 100, the power supply assembly 40 further includes a BMS power management system 43 and an auxiliary battery 44, wherein an input terminal of the BMS power management system 43 is connected to the fuel cell 41 and the auxiliary battery 44, respectively, and an output terminal of the BMS power management system 43 is connected to the power interface 431 for controlling the operations of the fuel cell 41 and the auxiliary battery 44. Thus, when the BMS power management system 43 determines that the fuel cell 41 is temporarily unable to supply power, the auxiliary battery 44 can be activated to supply power while the fuel cell 41 is in a standby state; when the BMS power management system 43 determines that the fuel cell 41 is capable of supplying power, the fuel cell 41 is enabled to supply power while the auxiliary battery 44 is in a standby state.

As shown in fig. 1, in the present embodiment, the power supply assembly 40 further includes a check valve 45 and a flow regulating valve 46, the check valve 45 and the flow regulating valve 46 are sequentially disposed on the connecting pipeline 32, the check valve 45 is used for limiting the hydrogen to flow from the hydrogen production material bag 31 to the fuel cell 41 so as to prevent the hydrogen from flowing back into the hydrogen production assembly 30, and the flow regulating valve 46 is used for regulating the flow rate of the hydrogen flowing through the connecting pipeline 32 so as to precisely control the power generation of the fuel cell 41.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
