Problems solved by technology

[0004] The air entering the stack needs to meet the temperature, humidity, pressure, and flow requirements. The mainstream solution in the world is that the flow and pressure are controlled by the air compressor, the temperature is controlled by the intercooler at the air compressor exhaust port, and the humidity is controlled by the air compressor. Humidifier control at the front end of the stack. This solution has a complex structure, high cost, and takes up a lot of system space. The humidifier technology is difficult. Most assembly plants and car companies need to purchase Korean thin-film humidifiers, which are not available in China. Alternative suppliers, increased cost

Abstract

The invention discloses an air compressor humidifying device for a proton exchange membrane fuel cell system. The device comprises a fuel cell; a high-pressure hydrogen cylinder which is connected with a hydrogen inlet of the fuel cell; a water pump which is connected with a tail discharge pure water outlet of the fuel cell; an air compressor, wherein an exhaust port of the air compressor is connected with an air inlet of the fuel cell; and an atomizing nozzle which is arranged at the air inlet end of the air compressor and is connected with the water pump. Tail discharge pure water generatedafter reaction of the fuel cell stack is recycled, and then the water is sprayed back to the air inlet end of the air compressor through the atomizing nozzle by utilizing the water pump, so the humidity of air is increased, and the temperature of the air is reduced.

Description

technical field [0001] The invention belongs to the technical field of fuel cells, in particular to an air compressor humidifier for a proton exchange membrane fuel cell system. Background technique [0002] The increasing tension of oil, the cleanliness and diversification of energy sources will be the main theme in the future, and fuel cell vehicles powered by hydrogen are regarded by the market as the ultimate form of vehicles. [0003] The fuel cell uses hydrogen-oxygen proton exchange to generate electricity, hydrogen is supplied by high-pressure hydrogen cylinders, and the air is rich in 21% oxygen, so the oxygen circuit is supplied by compressed air. [0004] The air entering the stack needs to meet the temperature, humidity, pressure, and flow requirements. The mainstream solution in the world is that the flow and pressure are controlled by the air compressor, the temperature is controlled by the intercooler at the air compressor exhaust port, and the humidity is con...
