The fuel cell 7 is for receiving the gas in the pipe for reaction; the three-way valve 8 is used to regulate the flow of exhaust gases into the mixing chamber 5.
Optionally, fig. 3 is a schematic structural diagram of a control system of a further fuel cell engine according to an embodiment of the disclosure. As shown in fig. 3, the control system includes: air filter 11, flowmeter 12, mixing chamber 5, air compressor 14, three-way valve 8, flowmeter 18, intercooler 15, pressure sensor 13, electronic throttle valve 17, humidifier 16. The systems are communicated through pipes 1, 2, 3, 4.
The air filter 11 may be a device for removing particulate impurities in air, the flowmeter 12 and the flowmeter 18 are used for measuring the flow rate of gas, the air compressor 14 may be used for providing reaction gas with certain pressure and flow rate for the electric pile by adjusting the rotating speed, the pressure sensor 13 is used for measuring the pressure, the electronic throttle valve 17 is used for realizing the back pressure of a pipeline between the air compressor 14 and the electronic throttle valve 18, and the intercooler 15 is used for reducing the temperature of the pressurized high-temperature gas so as to reduce the thermal load of an engine.
Specifically, air enters the mixing chamber 5 through the air filter 11 via the pipeline 1, then is input into the fuel cell stack 7 through the pipeline 3 via the pressure sensor 13, the nitrogen concentration sensor 6, the air compressor 14, the intercooler 15 and the humidifier 16 to participate in the reaction, and after the reaction, waste gas flows out through the pipeline 4 via the humidifier 16 and the electronic throttle valve 17, part of the waste gas flows into the mixing chamber 5 through the pipeline 2 when the three-way valve 8 is opened, and all the waste gas flows out through the pipeline 4 when the three-way valve 8 is closed.
As shown in fig. 1, a control method of a fuel cell engine provided in an embodiment of the present disclosure may specifically include the following steps:
s110, acquiring engine output power and voltage information of the fuel cell.
In this embodiment, the engine output power may be power that is externally output from the automobile engine. The voltage information can be different voltage values of the electric pile single bodies of the fuel cell 7 in the use process and variance values or electric pile single body voltage average values generated by all the electric pile single bodies due to different voltages; the voltage information is determined by the cell voltage of the fuel cell 7, and may include a cell voltage variance value and a cell voltage average value.
Wherein the fuel cell 7 stack is formed by stacking a plurality of fuel cell 7 single bodies in series. The fuel cells 7 may be referred to as stack cells, each of which has a voltage value during operation.
Specifically, the engine output power and the voltage values of the stack cells of the fuel cell 7 are obtained, and the voltage information is determined based on the voltage values of all the stack cells.
S120, adjusting the oxygen concentration of the input fuel cell according to the engine output power and the voltage information.
In the present embodiment, the oxygen concentration may be the volume occupied by oxygen in the gas input to the fuel cell 7.
It should be appreciated that the poor uniformity of stack cell of the fuel cell 7 during idle operation of the fuel cell 7 engine is mainly due to the excessive concentration of oxygen in the air input to the fuel cell 7.
Specifically, when the engine output is greater than a set threshold and the voltage information is greater than a set threshold, the three-way valve 8 is opened to mix the exhaust gas with the input air in the mixing chamber 5, so as to reduce the oxygen concentration of the mixed gas. Wherein, the waste gas is the waste gas after the fuel cell 7 pile reaction, and the oxygen concentration in the waste gas is far lower than the oxygen concentration in the input air.
According to the technical scheme, the waste gas after the electric pile reaction of the fuel cell 7 is directly introduced, so that the oxygen concentration in the gas input into the fuel cell 7 is reduced, the purpose of reducing the oxygen concentration in the gas input into the fuel cell 7 is achieved by only adding one three-way valve 8 without adding other equipment, and the cost is low and the implementation is easy.
Alternatively, the manner of adjusting the oxygen concentration input to the fuel cell 7 according to the engine output power and the voltage information may be: when the output power of the engine is larger than a first set threshold value and the voltage information is larger than a second set threshold value, mixing the waste gas with the input air to reduce the oxygen concentration of the mixed gas; the mixed gas is input to the fuel cell 7.
In this embodiment, the first set threshold may be a preset output power value. The second set threshold may be a predetermined constant, where the voltage information is a stack cell voltage variance value or a value of a predetermined constant when the stack cell voltage is an average value, and the setting of the threshold may be performed according to actual situations, and is not specifically limited in this embodiment.
Specifically, when the engine output power is greater than the first set threshold and the voltage information is greater than the second set threshold, the three-way valve 8 is opened, the exhaust gas and the input air are mixed in the mixing chamber 5 for the purpose of reducing the oxygen concentration of the mixed gas, and finally the mixed gas is input into the fuel cell 7.
Optionally, after mixing the exhaust gas with the input air, the method further comprises: determining the oxygen concentration in the mixed gas; the flow rate of the exhaust gas is adjusted according to the oxygen concentration.
It should be noted that air is typically nitrogen and oxygen, with a volume fraction of about 78% and a volume fraction of about 21% oxygen.
Specifically, the oxygen concentration in the mixed gas is first determined, and the oxygen concentration in the mixed gas may be obtained by measuring the nitrogen concentration. And then adjusting the flow of the waste gas according to the oxygen concentration, if the oxygen concentration is larger than a set threshold value, adjusting the flow of the waste gas, and if the oxygen concentration is smaller than the set threshold value, adjusting the flow of the waste gas.
Alternatively, the manner of determining the oxygen concentration in the mixed gas may be: acquiring the nitrogen concentration in the mixed gas; the oxygen concentration is determined based on the nitrogen concentration.
Specifically, the nitrogen concentration in the mixed gas may be acquired by the nitrogen concentration sensor 6, and then the oxygen concentration in the mixed gas may be determined from the nitrogen concentration.
Alternatively, the way to adjust the flow rate of the exhaust gas according to the oxygen concentration may be: if the oxygen concentration is greater than the third set threshold, the flow of the waste gas is regulated up until the oxygen concentration is equal to the third set threshold; and if the oxygen concentration is smaller than the third set threshold value, reducing the flow of the exhaust gas until the oxygen concentration is equal to the third set threshold value.
In this embodiment, the third set threshold may be a preset threshold, which may be defined according to practical situations, and is not specifically limited in this embodiment.
Specifically, if the obtained oxygen concentration is greater than the third set threshold, the flow rate of the exhaust gas is increased so as to reduce the oxygen concentration in the mixed gas until the oxygen concentration is equal to the third set threshold. And if the obtained oxygen concentration is smaller than the third set threshold value, regulating the flow of the waste gas to increase the oxygen concentration in the mixed gas until the oxygen concentration is equal to the third set threshold value. And if the obtained oxygen concentration is equal to the third set threshold value, not adjusting the flow of the exhaust gas.
The invention discloses a control method of an engine of a fuel cell 7, which comprises the following steps: acquiring engine output power and voltage information of the fuel cell 7; the oxygen concentration input to the fuel cell 7 is adjusted based on the engine output power and the voltage information. By using the method, the problem of poor consistency of the galvanic pile units of the fuel cell 7 in the idling process of the engine of the fuel cell 7 is solved by adjusting the oxygen concentration of the input fuel cell 7, and the running stability is improved.
Alternatively, as a first alternative embodiment of the present embodiment, fig. 4 is a flowchart of a control method of an engine of another fuel cell 7 provided in the embodiment of the present disclosure, as shown in fig. 4, first, it is determined whether the engine output is less than a (first set threshold), and if the engine output is greater than or equal to a, the three-way valve 8 closes the pipeline 2. If the engine output is less than or equal to a, continuing to determine whether the voltage information is greater than B (second set threshold), and if the voltage information is less than or equal to B, closing the three-way valve 8 to close the pipeline 2. If the voltage information is greater than B, the three-way valve 8 opens the pipeline 2, the nitrogen concentration sensor 6 acquires the nitrogen concentration at the pipeline 3, determines the oxygen concentration according to the nitrogen concentration, judges whether the oxygen concentration is less than C (third set threshold), if so, adjusts the three-way valve 8 to switch, reduces the flow of exhaust gas in the pipeline 2 to enable the oxygen concentration to be equal to C, and if not, adjusts the three-way valve 8 to switch, increases the flow of exhaust gas in the pipeline 2 to enable the oxygen concentration to be equal to C.
