PURPOSE: A fuel efficiency measuring device for a fuel cell vehicle is provided to easily separate a quick coupler by changing positions of high-pressure regulator and the quick coupler and excluding a flexible hose and a bent valve. CONSTITUTION: A fuel efficiency measuring device for a fuel cell vehicle comprises a hydrogen tank(10) and electronic balance(12) measuring a weight of the hydrogen tank. A high-pressure regulator(14) and quick coupler(16) are connected to an outlet portion of the hydrogen tank one by one. Air pressures of the front and rear parts of the quick coupler are decreased and the coupler is smoothly separated at the same time. |
