ABSTRACT:
The pump comprises a pump body, a control member, an elastic member, and blades. The pump body has a holding space, one or more pump inlets, and one or more pump outlets. The holding space, the pump inlets, and the pump outlets communicate with each other. The pump outlets communicate with a fuel outlet of the fuel storage device; while the pump inlets communicate with a fuel reservoir of the fuel storage device. The control member passes through the fuel storage device and is rotatably set in the holding space. The elastic member is set fixed on the pump body and connects with the control member. The blades are set in the holding space and connect with the control member. Thereby, no extra energy is needed for the pump to transport the fuel from the fuel reservoir to the fuel cell.
