An environmentally friendly hydrogen fuel cell system

Abstract

Disclosed is an environmentally friendly hydrogen fuel cell system which comprises an air compression conveying system, a high-pressure hydrogen storage tank, a hydrogenation device, a fuel cell stack, a power cell, a steam liquefier, a water storage device, an air compressor arranged in the air compression conveying system, an air compression conveying system capable of compressing air and then carrying out quantitative conveying, and an air inlet is arranged on the air compressor. The fuel cell stack is provided with a power generating device which is connected with a power battery so as tostore the electric quantity in time, and the power battery is connected with the electric motor to provide sufficient power for the operation of the electric motor. The steam generated by the fuel cell stack enters a steam liquefier through an exhaust pipe, is liquefied into water, and enters the water storage device for storage and standby. The structure design of the invention is scientific andreasonable, and can be widely applied to new energy electric vehicles, and can effectively collect and utilize product water of hydrogen fuel cell system operation, further improving the green environmental protection of hydrogen fuel cell system.

Description

technical field The invention relates to the technical field of hydrogen fuel cells, in particular to an environment-friendly hydrogen fuel cell system. Background technique Fuel cell is the most promising clean and efficient power generation technology in the 21st century. As a new type of power device, fuel cell has attracted widespread attention in recent years. The working process of the fuel cell not only has the advantages of no pollution, high efficiency, wide application, and no noise, but also has the characteristics of continuous operation and modularization. Fuel cells can be divided into three categories: 1. Direct fuel cells, which directly use hydrogen and light alcohols as fuel; 2. Indirect fuel cells, which convert light alcohols, natural gas, gasoline and other compounds After it is converted into hydrogen or a mixture of hydrogen, it is supplied to the fuel cell to generate electricity. Third, the regenerative fuel cell, the water generated by the fuel cel...

AI Technical Summary

Problems solved by technology

However, the current hydrogen fuel cell system often has a complex structure and messy connecting lines, which affects installation and later maintenance, and the design of the hydrogen fuel cell system applied to the car body is very small. In addition, the product water of the hydrogen-oxygen fuel cell Without reasonable collection, the random discharge of product water is an invisible waste of water resources
