Abstract

The invention relates to a high-altitude environment adaptability adjusting device for an air-cooled fuel cell. The device comprises a gas pressurization power source, an air injection duct, an adjusting device and a detection device. The gas pressurization power source is located at an air inlet of the air duct; the air-cooled fuel cell stack is located in the middle section of the air duct; theperiphery of the air-cooled fuel cell stack is connected with the air duct in a sealed mode; all air in the air duct flows through a cathode flow channel of the air-cooled fuel cell stack; and the adjusting device and the detection device are arranged in the air duct. The working pressure of cathode air of the air-cooled fuel cell is increased through a turbocharging fan, so that the oxygen supplyconcentration and temperature of the cathode are increased. Through the temperature and humidity adjusting device, the temperature and humidity characteristics of supplied air are further improved, the galvanic pile can reliably work at the high altitude of 5000 to 10000 meters, and the application space of an electric unmanned aerial vehicle is greatly expanded.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to an air-cooled fuel cell high-altitude environment adaptability adjustment device. Background technique [0002] Air-cooled fuel cells are used in unmanned aerial vehicles. When flying at high altitudes, due to the double drop of oxygen concentration and ambient temperature, the performance of the stack is greatly attenuated, and the unmanned aerial vehicle cannot be driven to fly reliably. Every time the altitude rises by 1000 meters, the atmospheric pressure drops by about 10KPa, the oxygen concentration drops by 1.5%, and the temperature drops by 6.5°C. Experiments have shown that the performance of the fuel cell decreases by 1.5% every time the altitude rises by about 300 meters. When the altitude exceeds 3500 meters, the performance of the fuel cell decreases to about 80% of the rated performance. If the altitude rises further, the battery performance will decline at an a...
