Technical Field

The invention belongs to the technical field of hydrogen energy sources, and particularly relates to a hydrogen energy motorcycle power system based on a hydrogen internal combustion engine.

Background

Hydrogen energy has been widely used as a clean and efficient energy source, and is particularly applied to energy power because not only energy density is high, but also the product after combustion is water, so that the hydrogen energy is an ideal clean, green and renewable energy source. There are two main forms of hydrogen used as automotive fuel: firstly, hydrogen is ionized and converted into electric energy, and the electric energy is realized through a fuel cell; the second is the conversion of chemical energy into mechanical energy by the combustion of hydrogen, which is realized by an internal combustion engine.

Hydrogen internal combustion engines are well established from a technical point of view, and the international use of hydrogen fuel for internal combustion engines is based mainly on the following recognition: one is that the internal combustion engine still has great development potential after more than 100 years of development, and the cost of the common hydrogen fuel internal combustion engine is only about 15 percent higher than that of the conventional gasoline engine and far lower than that of a fuel cell, so that the cost advantage is achieved; secondly, the hydrogen fuel internal combustion engine has various fuel adaptability, not only can use pure hydrogen as fuel, but also can use mixed fuel of hydrogen and natural gas and hydrogen and other fuels, and is an important way for reducing dependence on petroleum at present; thirdly, the hydrogen fuel internal combustion engine does not discharge greenhouse gas carbon dioxide and carbon oxides, hydrocarbons and soot; fourthly, the hydrogen fuel internal combustion engine does not need a heat engine, does not have the cold start problem and has better fuel economy.

However, the storage of hydrogen gas, whether in high pressure gas or low temperature liquid state, is not suitable for use on mobile vehicles, especially on small and light vehicles such as hydrogen bicycles and hydrogen motorcycles, which are the mainstream at present. Because such storage methods need to maintain high storage pressure or low hydrogen storage temperature, they are not safe and portable.

The solid-state hydrogen storage technology is combined through chemical bonds, so that hydrogen is stored in metal hydride, has the characteristics of compactness, high efficiency and safety, and is an ideal storage mode in the mobile application of hydrogen energy.
