Abstract

See full text

A hydrogen refueling station based on low-temperature and high-pressure graded hydrogen storage includes: a liquid hydrogen storage tank, n≥2 hydrogen storage vessels that are low-temperature and high-pressure vessels, a booster pump and a high-pressure vaporizer, disposed between the storage tank and the storage vessels. A temperature value and a maximum pressure value of gaseous hydrogen stored in the storage vessels are Tn and Pn; when n=2, T12, P12; and when n≥3, T1< . . . T(n-1)n, P1< . . . P(n-1)n. A main refueling pipe is configured to communicate the hydrogen storage vessels with the hydrogen dispenser. A refueling controller is configured to, based on an ascending order of the temperature values, sequentially control corresponding hydrogen storage vessels to communicate with the hydrogen dispenser for participation in a refueling operation. A gaseous hydrogen refueling method based on the hydrogen refueling station is further provided.
