Description

technical field [0001] The invention relates to the technical field of liquid organic hydride catalytic hydrogen production, in particular to a vehicle-mounted hydrogen supply system and method based on a hollow fiber membrane microreactor. Background technique [0002] With the development of hydrogen fuel cell vehicles, hydrogen is regarded as an important bridge connecting fossil energy and renewable energy. Hydrogen energy has the characteristics of abundant reserves, wide range of sources, high energy density, recyclability, and zero emission of greenhouse gases and pollutants. It is recognized as a clean energy source and helps to solve problems such as energy crisis, environmental pollution, and global warming. Hydrogen is gaseous at normal temperature and pressure, and its density is only 7.14% of that of air, so the storage of hydrogen is the key. Based on the fact that hydrogen fuel cell vehicles must meet the requirements of high efficiency, safety, and low cost,...
