Problems solved by technology

[0008] Although the measurement method based on the temperature and pressure changes of the hydrogen fuel tank has the advantage of calculating the amount of hydrogen purge, the error of the pressure and temperature sensors is large and requires soaking
[0009] Moreover, although the measurement method based on the amount of hydrogen supplied has the advantage of being able to calculate the amount of hydrogen purge, the error of the hydrogen flow sensor is quite large
[0010] Also, although the measurement method based on fuel cell amperage has the advantage that the calculation of amperage and reaction rate is excellent, the amount of hydrogen purge cannot be estimated and the error of the amperometric sensor is quite large

Abstract

The invention relates to a system and method for measuring the fuel-cell vehicle of fuel-cell vehicle. The fuel-cell vehicle measuring system comprises: a fuel supply tank for supplying hydrogen to the fuel-cell of vehicle as fuel during the fuel efficiency measuring course; and a precise electronic balance for measuring the weight of the fuel supply tank. The fuel efficiency is measured based onthe vehicle miles and weight variety of the fuel supply tank measured by the electronic balance in the course of fuel efficiency measuring. According to the fuel efficiency measuring system, the fuelefficiency can be calculated more precisely without using a hydrogen tank mounted in the vehicle.

Description

Technical field [0001] The present invention relates to a fuel efficiency measurement system and method for a fuel cell vehicle, which can accurately measure the fuel efficiency of a fuel cell vehicle. Background technique [0002] Generally, fuel cells are considered to be the future power generation system due to their high power generation efficiency and zero emission characteristics. Fuel cells have been widely studied as a vehicle power source, which can solve various problems such as environmental pollution and global warming that have been proposed in recent years. [0003] A fuel cell is a device that directly converts chemical energy generated by the oxidation of active substances, such as hydrogen (such as LNG, LPG, methanol, etc.) into electrical energy through an electrochemical reaction. Generally speaking, fuel cells use hydrogen, which is easily generated from natural gas, and oxygen in the air. [0004] In a hydrogen fuel cell vehicle equipped with the above-menti...
