Method for adjusting output of fuel cell system

1. A method for adjusting an output of a fuel cell system, the method comprising:

comparing an average air flow rate required for driving a vehicle and an actually introduced average air flow rate and calculating an average air flow rate; and

comparing the average air flow rate with a preset air flow rate and adjusting an available output of the vehicle.

2. The method according to claim 1 , wherein the comparing of the average air flow rate with the preset average air flow rate includes:

comparing the calculated average air flow rate with a first air flow rate;

when the average air flow rate is greater than the first air flow rate, comparing the average air flow rate with a value between the first air flow rate and a second air flow rate;

when the average air flow rate is not a value between the first air flow rate and the second air flow rate, comparing the average air flow rate with a value between the second air flow rate and a third air flow rate; and

when the average air flow rate is not a value between the second air flow rate and the third air flow rate, determining whether the average air flow rate is a value greater than the third air flow rate.

3. The method according to claim 2 , further comprising:

when the average air flow rate is a value smaller than the first air flow rate, continuously monitoring the average air flow rate.

4. The method according to claim 2 , wherein, in the comparing of the average air flow rate with a value between the first air flow rate and the second air flow rate, when the average air flow rate is a value between the first air flow rate and the second air flow rate, an output available current is limited to 80% of a normal output of the fuel cell system.

5. The method according to claim 2 , wherein, in the comparing of the average air flow rate with a value between the second air flow rate and the third air flow rate, when the average air flow rate is a value between the second air flow rate and the third air flow rate, an output available current is limited to 60% of a normal output of the fuel cell system.

6. The method according to claim 2 , wherein, in the determining whether the average air flow rate is greater than the third air flow rate, when the average air flow rate is a value greater than the third air flow rate, an output available current is limited to 40% of the normal output of the fuel cell system.

7. The method according to claim 2 , wherein the first air flow rate is an air flow rate above 80% of the normal output of the fuel cell system.

8. The method according to claim 2 , wherein the second air flow rate is an air flow rate within a range from 60% to 80% of the normal output of the fuel cell system.

9. The method according to claim 2 , wherein the third air flow rate is an air flow rate within a range from 40% to 60% of the normal output of the fuel cell system.

10. The method according to claim 1 , further comprising, after the adjusting of the available output of the vehicle, performing controlling, by the fuel cell system, to recover a wet state or a dry state.

11. A non-transitory computer readable medium containing program instructions executed by a processor, the computer readable medium comprising:

program instructions that compare an average air flow rate required for driving a vehicle and an actually introduced average air flow rate and calculate an average air flow rate; and

program instructions that compare the average air flow rate with a preset air flow rate and adjust an available output of the vehicle.
