Problems solved by technology

High-pressure gaseous hydrogen storage is widely used, easy to operate, low in cost, and fast in charging and discharging hydrogen, but it requires heavy pressure-resistant containers, consumes a lot of hydrogen compression work, and has unsafe factors such as hydrogen leakage and container explosion.
Cryogenic liquid hydrogen storage has a wide range of applications in hydrogen refueling stations around the world, but its application in vehicle-mounted systems is immature and has potential safety hazards
In addition, limited by technology, the cost of domestic liquid hydrogen application is very high

Abstract

The invention provides a hydrogen fuel cell power-assisted bicycle. The bicycle comprises a power system and a frame, the power system comprises a hydrogen storage tank, a fuel cell device, a controldevice and a driving device; the frame specifically comprises a cross beam and a main vertical pipe, the rear end of the cross beam is connected with the main vertical pipe, the cross beam and the main vertical pipe are hollow, the rear end of the cross beam is provided with a ventilation opening communicating with the cross beam and the inner space of the main vertical pipe, and the side wall ofthe cross beam close to the front end of the cross beam is provided with an air outlet. The hydrogen storage tank is arranged in the cross beam, the fuel cell stack is arranged in the main vertical pipe, and an air outlet of the fuel cell stack is communicated with the ventilation opening, so that hot air exhausted by the fuel cell stack enters the cross beam through the ventilation opening and isexhausted from the air outlet after flowing through the outer surface of the hydrogen storage tank. Waste heat generated during operation of the fuel cell stack is utilized to realize thermal self-compensation.

Description

technical field [0001] The present invention relates to the technical field of electric bicycles, hydrogen storage technology and fuel cell technology, in particular, the present invention relates to a hydrogen fuel cell assisted bicycle. Background technique [0002] Hydrogen energy is considered to be an ideal clean energy, which has the advantages of light weight, abundant reserves, and environmental friendliness. The main industrial chain of hydrogen energy includes upstream hydrogen production, midstream hydrogen transportation and storage, downstream hydrogen refueling stations, hydrogen fuel cells and applications. Midstream hydrogen storage includes high-pressure gaseous hydrogen storage, low-temperature liquid hydrogen storage and solid-state hydrogen storage. High-pressure gaseous hydrogen storage is widely used, easy to operate, low in cost, and fast in charging and discharging hydrogen, but it requires heavy pressure-resistant containers, consumes a lot of hydro...
