Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Fig. 1 illustratively shows a kind of fuel cell start-up control method flow signal provided in an embodiment of the present invention
Figure, as shown in Figure 1, this approach includes the following steps：
Step 101, start two-way DC converters, when the two-way DC converters enter decompression mode, start air compressor machine
DC/AC inverters；
Step 102, air compressor machine is electrically connected through two-way DC converters with power battery, is set when the motor speed of air compressor machine is more than

Step 103, when determining that the parameter of fuel cell feedback is more than startup threshold value, the system that determines is completed to start.
Fig. 2 is that air subsystem provided in an embodiment of the present invention is electrically connected schematic diagram, as shown in Fig. 2, the air subsystem
System mainly includes two-way DC converters, air compressor machine DC/AC inverters, air compressor machine and power battery.
Specifically, in Fig. 2 it is successively from left to right power battery, two-way DC/DC converters, air compressor machine DC/AC inverters
And air compressor motor.Wherein, air compressor machine exports three-phase alternating current by two-way DC/DC from power battery electricity-taking after inverter
Electricity.Due to the big comparison of power battery carried charge, so being capable of providing enough power outputs during air subsystem starts.
It should be noted that the startup that the present invention implements the fuel cell provided mainly passes through hydrogen subsystem and air
Subsystem starts to complete.In the embodiment of the present invention, mainly completed to air subsystem by controller when fuel cell start-up
The control of system and hydrogen subsystem.
In a step 101, after system electrification, controller first starts two-way DC converters, when determining two-way DC converters
Into after decompression mode, then controller can start air compressor machine DC/AC inverters.
In a step 102, since air compressor machine passes through two-way DC converters and air compressor machine DC/AC inverters and power battery electricity
Connection, it is possible to start air compressor machine by setting initial air flow, and air compressor machine is under the power supply that power battery provides,
The motor of air compressor machine starts to rotate.
When controller determines that the motor speed of air compressor machine is more than given threshold, then it can determine that air subsystem has started
At.In embodiments of the present invention, it due to the startup of air subsystem, uses user's power battery instead and is powered, pass through two-way DC/
DC converters connect user's power battery and air compressor machine inverter, such air subsystem can obtain larger in startup stage
Power, so as to larger torque startup, shorten and start the time.
After completing air subsystem startup, hydrogen subsystem can be started, by starting hydrogen subsystem, can be made
Hydrogen is sent to fuel cell by hydrogen subsystem.
In the above method, using first for air again for the control strategy of hydrogen：It is less than since air subsystem starts speed
Hydrogen subsystem, and in a short time not for hydrogen, air mass flow it is smaller in the case of, fuel cell not will produce high voltage,
Therefore first start air subsystem, restart hydrogen subsystem after air mass flow or rotating speed reach certain value, both shortened
The fuel cell start-up time, while it is excessive and lead to fuel cell hydrogen to avoid high voltage occur and anode and cathode pressure difference
The problem of leakage rate increases.
It should be noted that in a step 102, before confirming startup hydrogen subsystem, if confirming the motor of air compressor machine
It when rotating speed is less than the given threshold, then needs to carry out fault detect to air subsystem, if confirming air after fault detect
Subsystem can then continue the motor rotary speed for observing air compressor machine there is no failure, and when determining air subsystem has event
After barrier, then need to carry out system-down.
It should be noted that in above-mentioned steps, given threshold is one according to the customized numerical value of system, in the present invention
In embodiment, the size of given threshold is not limited.
In step 103, hydrogen is sent to fuel cell due to hydrogen subsystem, then fuel cell can start to transport
Row, and after fuel cell operation, the parameters item of fuel cell can be fed back, when controller receives fuel cell feedback
It after parameters item, needs to compare parameters item and the startup threshold value of storage, if fuel cell feedback is each
When parameter item is more than startup threshold value, then it can be confirmed that fuel cell is completed to start, and system can be with normal operation；If fuel cell
When the parameters item of feedback is there are one startup threshold value is less than, then confirms that fuel cell does not complete and start, then need hydrogen subsystem
System continues to send hydrogen to fuel cell, until controller confirms that fuel cell is completed to start or waiting system starts time-out meter
When after shut down.
In embodiments of the present invention, the concrete numerical value of the parameters item of fuel cell feedback is not limited, further
Ground, the concrete numerical value to starting threshold value also do not limit.
In conclusion a kind of fuel cell start-up control method, in this way, since air compressor machine is through two-way DC converters
It being electrically connected with power battery, such air compressor machine obtains larger power in startup stage, can quickly be started with larger torque,
So as to shorten the startup time；Further, complete air compressor machine start after start hydrogen subsystem, avoid first for hydrogen again
For making fuel cell generate high voltage and negative and positive due to air subsystem starts failure but hydrogen has been injected into air event
Extreme pressure difference it is excessive and the case where cause fuel cell leakage rate to increase, play a protective role to fuel cell.This method solve
Existing fuel cell turns high pressure DC converters there are the low pressure for powering to air compressor machine in starting process easily to be damaged because of overcurrent
It is bad, thereby increases and it is possible to generate high voltage in the case where air is not yet supplied and anode and cathode pressure difference is excessive and lead to fuel cell hydrogen
The problem of leakage rate increases.
