Problems solved by technology

[0006] However, since the pressure in the hydrogen tank is very high, the resolution of the pressure sensor is low, the temperature variation range is large, and the resolution of the temperature sensor is low, so there is an obvious error in calculating the mass of hydrogen in the hydrogen tank
As a result, more errors are created in the vehicle's displayed fuel efficiency and displayed remaining driving distance, thereby frustrating consumers

Abstract

A hydrogen consumption measuring method for a fuel cell system includes steps of: calculating an amount of hydrogen consumed for a representative section from a first pressure at a time when hydrogen is supplied into an anode and a second pressure at a time when the hydrogen is no longer supplied to the anode; and calculating a total amount of hydrogen consumed by accumulating amounts of hydrogen consumed from a plurality of sections.

Description

technical field [0001] The invention relates to a hydrogen consumption measurement method for a fuel cell system. More particularly, it relates to a hydrogen consumption measurement method for a fuel cell system capable of increasing calculation accuracy of instantaneous fuel efficiency and average fuel efficiency in the case of driving a vehicle. Background technique [0002] A hydrogen fuel cell vehicle is a vehicle that generates propulsion using an electric motor that is driven by electricity generated by the reaction of hydrogen and oxygen; it is possible to measure the pressure and temperature of hydrogen in the fuel (hydrogen) tank by measuring The amount of hydrogen in the vehicle; the amount of fuel consumed in the vehicle can be calculated by measuring the change in the amount of hydrogen in the fuel tank. [0003] However, for a hydrogen fuel cell vehicle, since high-pressure hydrogen gas of 700 bar or more is used as fuel, and the temperature use range can be as...
