1. A fuel cell system, comprising:
a fuel cell configured to generate electricity using a fuel gas and air;
an air supply configured to supply air to the fuel cell;
a temperature meter configured to measure a temperature of the fuel cell;
a power meter configured to measure an output power level of the fuel cell; and
a controller configured to control the air supply to adjust an amount of air to be supplied to the fuel cell, in response to the temperature of the fuel cell and in response to the temperature of the fuel cell in conjunction with the output power level of the fuel cell, based on a set of threshold temperatures comprising: a first set temperature, a second set temperature, and a third set temperature;
wherein
the first set temperature is a highest temperature of the set of temperatures,
the second set temperature is in conjunction with an output power level of the fuel cell that is less then a first output power level, and
the third set temperature is lower than the second set temperature and is in conjunction with an output power level of the fuel cell that is greater than or equal to the first output power level.
