Beschreibung
Zusammenfassung:	The present invention provides a power supply method and system for a hydrogen fuel cell stack, and a hydrogen powered motorcycle and a driving method and system thereof, the power supply method includes: a control chip detecting the operating states of the hydrogen fuel cell stack and the lithium battery pack; when the hydrogen fuel cell stack and the lithium battery pack are free of faults, obtaining the output voltage of the lithium battery pack; when the output voltage is lower than the charge-on threshold, the hydrogen fuel cell stack powering the lithium battery pack; when the output voltage is higher than the charge-stop threshold, disconnecting the circuit of the hydrogen fuel cell stack powering the lithium battery pack, when the output voltage is more than or equal to the charge-on threshold and less than or equal to the charge-stop threshold, the circuit of the hydrogen fuel cell stack remaining to power the lithium battery pack; and when the output voltage is higher than the charge-stop threshold, disconnecting the circuit oi the hydrogen fuel cell stack powering the lithium battery pack. The aforementioned technical solution uses hydrogen energy as the electrical energy powering the motorcycle as much as possible under the protection of the hydrogen fuel cell stack.
