Abstract

Abstract:

This study analyzes the working model and refueling performance of a 35 MPa/70 MPa hydrogen dispenser and assesses the user experience of hydrogen fuel cell vehicles and the restriction conditions of on-board hydrogen storage tanks. Based on the results, a universal evaluation index of the refueling performance of a hydrogen dispenser is proposed. A refueling test was conducted on a 35 MPa/70 MPa hydrogen dispenser for passenger and logistics vehicles, and the refueling performance of the dispenser was measured by the evaluation index. The index is direct and reliable, simple and easy to calculate, and comprehensively reflects the refueling performance of the hydrogen dispenser. The index is applicable to actual performance evaluations of 35 MPa/70 MPa hydrogen dispensers and provides technical and theoretical support for ensuring their reliable operation.

Key words: hydrogen energy, hydrogen dispenser, refueling performance, evaluation index
