Description

technical field [0001] The invention belongs to the technical field of power machinery and relates to a vehicle power system, in particular to a hydrogen energy vehicle power system for purifying ambient air. Background technique [0002] In the 21st century, the automobile engine industry has developed rapidly, but gasoline engines and diesel engines are still the main types of automobile engines. Gasoline and diesel are non-renewable resources. In order to alleviate a series of negative effects brought about by the shortage of petroleum resources and reduce air pollution and vehicle engine exhaust emissions, it is necessary to find alternative fuels for engines, and hydrogen energy is currently the most ideal clean fuel. . Hydrogen energy is a renewable resource among many alternative energy sources. It has a high calorific value and most of the products after combustion are water vapor. It is an ideal green fuel. Hydrogen energy as an alternative fuel can solve two majo...
