Abstract
The present invention provides an improved fuel efficiency measuring system for a fuel cell vehicle which simplifies various valves and hydrogen lines and modulizes its individual elements. More specifically, the present invention provides an improved fuel efficiency measuring system for a fuel cell vehicle that eliminates a purging hydrogen tank previously used for removing residual air in a hydrogen supply line and instead removes residual air in a hydrogen supply line by using a vehicle side hydrogen tank. Additionally, the present invention simplifies couplers installed in a hydrogen supply line, and considerably reduces manufacturing costs by eliminating a high-cost break-away coupler adapted to couple a fuel efficiency measuring unit and the vehicle side.
