Abstract
A fuel efficiency measurement system includes a fuel supply tank for supplying hydrogen to be used as a fuel to a fuel cell of the vehicle during measurement of fuel efficiency and a precision electronic balance for detecting a weight of the fuel supply tank so as to perform the measurement of fuel efficiency based on a vehicle driving distance and a change in weight of the fuel supply tank measured by the electronic balance during measurement of fuel efficiency. According to the fuel efficiency measurement system, it is possible to more accurately calculate fuel efficiency without using hydrogen of a hydrogen tank installed in the vehicle.
