Description
Technical Field
The present invention relates to a hydrogen gas exhaust control method for a vehicle fuel cell system.
Background
The current vehicle fuel cell system adopts a hydrogen circulating fuel supply system in order to reduce hydrogen consumption and improve fuel economy of the whole vehicle. However, the hydrogen system with sealed circulation inevitably causes the accumulation of non-hydrogen impurities in the system along with the increase of the operation time of the fuel cell, and if the impurity gas is not discharged in time, the performance of the fuel cell system is seriously influenced.
In the prior art, a method of opening a hydrogen discharge valve at a fixed frequency is mostly adopted for discharging impurities in a system. However, this is an open-loop control scheme, and if the hydrogen discharge frequency is too high and the hydrogen discharge time is too long, the hydrogen discharge will be too much, the hydrogen consumption will be increased, the system economy will be reduced, and at the same time, too high hydrogen discharge concentration will also bring about the hydrogen safety problem. If the hydrogen discharge frequency is too low and the hydrogen discharge time is too short, impurities in the system can accumulate, and the efficiency of the fuel cell is reduced.
In addition, frequent opening and closing of the hydrogen discharge valve easily causes pressure fluctuation of hydrogen in the system, which is not favorable for stable operation of the fuel cell.
The prior art venting of hydrogen has the following drawbacks:
1. the existing hydrogen gas exhaust open-loop control scheme can not accurately control the frequency and the time of hydrogen exhaust, so that hydrogen gas waste or impurity gas accumulation in a system is caused.
2. The hydrogen discharge valve is frequently opened, so that the pressure fluctuation of hydrogen in the system is easily caused, and the stability of the fuel cell is influenced.

Detailed Description
The following detailed description of the present invention is provided in conjunction with the accompanying drawings, but it should be understood that the scope of the present invention is not limited to the specific embodiments.
Throughout the specification and claims, unless explicitly stated otherwise, the word "comprise", or variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated element or component but not the exclusion of any other element or component.
As shown in fig. 1, a hydrogen gas exhaust apparatus for a vehicle fuel cell system according to a preferred embodiment of the present invention includes a hydrogen injector 2, a stack 4, an exhaust valve 5, a circulation pump 6, and a hydrogen concentration sensor 7. The stack 4 is disposed downstream of the hydrogen injector 2. The exhaust valve 5 is disposed downstream of the stack 4. The air inlet end of the circulating pump 6 is communicated with a pipeline between the galvanic pile 4 and the exhaust valve 5, and the air outlet end of the circulating pump 6 is communicated with the hydrogen injector 2. The hydrogen pressure sensor 3 is provided on a pipe between the hydrogen injector 2 and the stack 4. A hydrogen concentration sensor 7 is provided on the line between the circulation pump 6 and the stack 4.
In some embodiments, the hydrogen exhaust apparatus for a vehicle fuel cell system further includes a controller 1, and the controller 1 is in data connection with the hydrogen injector 2, the hydrogen pressure sensor 3, the stack 4, the exhaust valve 5, the circulation pump 6, and the hydrogen concentration sensor 7 at the same time. The controller 1 is used for monitoring the working conditions of the hydrogen injector 2 and the galvanic pile 4 and controlling the hydrogen injector 2, the discharge valve 5 of the galvanic pile 4 and the circulating pump 6 through data fed back by the hydrogen pressure sensor 3 and the hydrogen concentration sensor 7.
As shown in fig. 2, a hydrogen gas exhaust control method for a fuel cell system for a vehicle according to a preferred embodiment of the present invention: in the initial state of the fuel cell system, the exhaust valve 5 is closed, and hydrogen gas enters the stack 4 from the hydrogen injector 2 to react. The residual hydrogen is re-introduced into the electric pile 4 for reaction through the circulating pump 6. Along with the continuous reaction, the impurity gas in the hydrogen cavity in the galvanic pile 4 is gradually accumulated, so that the hydrogen concentration is reduced. When the hydrogen concentration sensor 7 monitors that the concentration of the circulating hydrogen in the fuel cell system is less than a first threshold value, the controller 1 controls the exhaust valve 5 to be opened to discharge impurity gases. The frequency Frq and the duty ratio Ducyc at which the exhaust valve 5 is opened are inversely proportional to the hydrogen concentration, i.e., the lower the hydrogen concentration is, the greater the frequency Frq and the duty ratio Ducyc at which the exhaust valve 5 is opened are.
When the hydrogen concentration sensor 7 monitors that the concentration of the hydrogen circulating in the fuel cell system is greater than the standard threshold (the relationship between the standard threshold and the first threshold is that the first threshold is less than the standard threshold, the first threshold of the embodiment is about 90%, and the standard threshold is about 95%), the controller 1 judges that the discharge of the impurity gas is completed, and the controller 1 controls the exhaust valve 5 to be closed.
In the above-described hydrogen gas exhaust control process, since the pressure of the hydrogen fuel cell system in the stack 5 is decreased due to the opening of the exhaust valve 5, it is necessary to add the hydrogen pressure compensation control in the process.
As shown in fig. 3, in some embodiments, the hydrogen gas exhaust control method further includes a hydrogen pressure compensation function: when the fuel cell system is in operation, the controller 1 sets the operation basic duty ratio of the hydrogen injector 2 according to the hydrogen demand pressure of the fuel cell system, so that the hydrogen pressure in the stack 4 is maintained within the demand pressure. When the venting valve 5 is opened and the rate of decrease of the hydrogen pressure monitored by the hydrogen pressure sensor 3 is > a second threshold value (which in the present example is about 100 mbar/s), the hydrogen pressure compensation function is triggered.
The hydrogen pressure compensation process is described as follows: the compensation coefficient MAP (which is a data table summarized by experimental data) can be queried according to the hydrogen pressure drop rate, and the working duty ratio of the new injector = the working basic duty ratio x compensation coefficient of the injector is calculated; the pressure drop rate and the compensation coefficient are in a direct proportion relation, namely the larger the pressure drop rate is, the larger the compensation coefficient is, and the compensation coefficient is a value larger than 1.
When the exhaust valve 5 is closed or the difference between the hydrogen pressure monitored by the hydrogen pressure sensor 3 and the required pressure is smaller than a third threshold value, the hydrogen pressure compensation process is judged to be finished, and the controller 1 restores the working duty ratio of the hydrogen injector 2 to the working basic duty ratio.
In summary, the hydrogen gas exhaust control method for a fuel cell system for a vehicle of the present invention has the following advantages: firstly, the opening frequency and the opening time of the exhaust valve can be controlled in a closed-loop manner according to the concentration of the circulating hydrogen, so that the impurity gas in the system can be discharged in time, and meanwhile, the increase of hydrogen consumption caused by excessive exhaust is avoided. In addition, in the hydrogen exhaust stage, the system automatically compensates the hydrogen pressure, so that the hydrogen pressure in the system is stable, and the stable operation of the fuel cell is ensured.

It is not intended to limit the invention to the precise form disclosed, and obviously many modifications and variations are possible in light of the above teaching.
