Description
Technical Field
The invention relates to the field of a hydrogen supply system of a fuel cell automobile, in particular to a hydrogen purity detection device of the hydrogen supply system.
Background
The fuel cell vehicle is a new energy power vehicle which directly converts chemical energy in fuel and oxide into electric energy to drive a motor through electrochemical reaction of the fuel cell without fuel combustion. The fuel used in the current vehicle-mounted fuel cell system is generally high-purity hydrogen gas with a purity of 99% or more or high-purity hydrogen reformed gas obtained by reforming a hydrogen-containing fuel. Several main methods for obtaining high-purity hydrogen reformed gas from hydrogen-containing fuel reforming include hydrogen production from byproducts in the chlor-alkali industry, hydrogen production from chemical raw materials (methanol cracking, ethanol cracking, liquid ammonia cracking, etc.), novel hydrogen production methods (biomass, photochemistry, etc.), and hydrogen production from petrochemical resources (petroleum cracking, water gas method, etc.).
When the replacement of the hydrogen bottle of the fuel cell is carried out or the reformed hydrogen adopted is not strictly detected, the gas in the hydrogen bottle has more gas impurities, such as N2、O2、H2O, CO, nitrogen oxides, chlorides, methane, etc.; and the excessive content of hydrogen-supplying gas impurities can directly cause the poisoning of the anode catalyst of the vehicle hydrogen fuel cell, the serious performance reduction is caused, and the service life of the vehicle fuel cell is greatly reduced. Therefore, it is necessary to detect and identify impurities in the hydrogen gas of the fuel cell vehicle air supply system in advance to ensure that the back end of the hydrogen gas is supplied to the fuel cell systemThe quality of the hydrogen reaches the use requirement.
The traditional method for detecting impurity in gas mainly comprises collecting target gas, and analyzing and detecting the gas sample on a specific mass spectrometer device to determine the content of each component in the gas, such as patent CN 201911102094.2; although this method can accurately determine the specific content of each gas, the complicated collection and detection process requires a lot of time and labor.
Secondly, there is also patent CN201810634256.6 that component content in the anode subsystem is detected by the anode model of the fuel cell system, and then component content of new hydrogen is calculated back by the components of the anode subsystem, but the method needs a fuel cell anode component estimation model with sufficient accuracy, and from the perspective of engineering application, the method is complicated, and the model involves many physical field calculation processes such as fuel cell, etc., and needs a large amount of system and stack test data to verify the model estimation accurately.
With the increasing of fuel cell vehicles in online operation at home and abroad, in order to avoid the great reduction of the performance and the service life of a fuel cell stack caused by impure front-end hydrogen gas sources of the fuel cell, the hydrogen entering a fuel cell system needs to be subjected to advanced purity detection so as to avoid unnecessary damage of the stack.
