Problems solved by technology

[0010] In other words, since a large error occurs between the measured value of the hydrogen concentration and the estimated value of the hydrogen concentration in the fuel cell stop mode, the estimated value is significantly lower than the actual hydrogen concentration, which causes excess hydrogen exchange to be performed when the fuel cell stop mode is released. gas problem

Abstract

The application relates to hydrogen concentration estimating method and system for a fuel cell. A hydrogen concentration estimating method for a fuel cell includes: measuring a flow rate of air supplied to a fuel cell stack, and comparing the measured flow rate of the air with a predetermined flow rate; determining a model of an air processing system according to a comparison result; and estimating hydrogen concentration of a fuel processing system based on the determined model of the air processing system.

Description

technical field [0001] The present disclosure generally relates to a hydrogen concentration estimating method and system for a fuel cell, and more particularly, to a hydrogen concentration estimating method and system in which the hydrogen concentration is estimated by variably setting a model according to an air supply amount of a fuel cell stack. Background technique [0002] As known in the art, a fuel cell is a device that converts chemical energy of fuel into electrical energy through a redox reaction of hydrogen and oxygen supplied from a hydrogen supply device and an air supply device, respectively, and includes a fuel cell for generating electricity group, cooling system for cooling the fuel cell group, etc. [0003] In other words, hydrogen gas is supplied to the anode of the fuel cell stack, and an oxidation reaction of hydrogen oxidizing gas occurs at the anode to generate hydrogen ions (protons) and electrons. At this time, protons and electrons generated at the...
