Background

Most of the existing propulsion devices applied to automobiles, airplanes, ships, rockets and the like rely on fossil fuels to work, and can be classified into piston engines, turbine engines and the like according to types. Common gasoline engines and diesel engines belong to reciprocating piston internal combustion engines, which convert chemical energy of fuel into mechanical energy of piston motion and provide power for automobiles. The gasoline engine has high rotating speed, low quality, low noise and easy starting; the diesel engine has large compression ratio, high heat efficiency, and better economic performance and discharge performance than the gasoline engine. Turbine engines are mostly used in aviation, have a compressor, a combustor and a gas turbine, and have made significant technical progress for many years: the maximum thrust of the civil large-bypass-ratio turbofan engine exceeds 50000daN, and the noise is reduced by 20 dB. During the working process of the power devices, substances harmful to the environment, such as carbon dioxide, sulfur dioxide and the like, can be generated due to the combustion of fossil fuels, and the global greenhouse effect, acid rain and the like are caused. Some automobiles use electric motors or hybrid power, and have less environmental impact than traditional automobiles, but the technology is not mature.

Hydrogen is an important industrial raw material and also a clean renewable energy source, and can be used as a fuel for automobiles and the like. The combustion heat value of hydrogen is high, and the heat quantity after each kilogram of hydrogen is combusted is about 3 times of that of gasoline, 3.9 times of alcohol and 4.5 times of that of coke. The product of hydrogen combustion is water, which does not cause environmental pollution, and can prepare hydrogen by decomposing water. Hydrogen is difficult to store at normal temperature and normal pressure, a large amount of hydrogen can be absorbed by using special solution in China, more than 50 kilograms of hydrogen can be absorbed by one cubic meter of solution, the hydrogen can be stably stored in the ordinary time, the hydrogen can be released by adding a catalyst, and the hydrogen storage material can be repeatedly used for 2000 times. Meanwhile, the storage and transportation technology of hydrogen also makes great progress, and the technologies all provide powerful support for the utilization of the hydrogen.
