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 power system of a thermal self-compensation type hydrogen fuel cell power-assisted bicycle. The power system comprises a hydrogen storage tank, a fuel cell stack, a control device and a driving device. The power-assisted bicycle is provided with a bicycle frame, and the bicycle frame specifically comprises a front oblique beam, a vertical pipe, a first shell arranged on the front side of the vertical pipe and a second shell arranged on the rear side of the vertical pipe which are connected. The interior of the first shell and the interior of the second shell are both hollow, an air outlet is formed in the first shell, an air inlet is formed in the second shell, the internal space of the first shell is connected with the internal space of the second shell through aplurality of air pipelines, a first air flow channel is formed in the first shell, and a second air flow channel is formed in the internal space of the multiple air pipelines; and the hydrogen storagetank is arranged in the first air flow channel, the fuel cell stack is arranged in the second shell, and hot air exhausted by the fuel cell stack enters the first air flow channel through the secondair flow channel and is exhausted from the air outlet after flowing through the hydrogen storage tank. Waste heat generated during operation of the fuel cell stack is utilized to realize thermal compensation.

Description

technical field [0001] The present invention relates to the technical field of power systems of electric bicycles, hydrogen storage technology and fuel cell technology. 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 hydrogen compression work, and has unsafe factors such as hydrogen leakage ...
