[0002] Hydrogen, with the chemical formula H2 and a molecular weight of 2.01588, is a highly flammable gas at room temperature and pressure. It is a colorless, transparent, odorless, and insoluble gas in water. As a clean energy source, hydrogen is widely used. When some cars that need to be refueled with hydrogen are running low on hydrogen, emergency refueling vehicles are needed to refuel the cars to ensure normal driving of the cars.
