in an alternative embodiment, the plurality of fuel cell systems includes at least a first fuel cell system and a second fuel cell system, and in the case where the required power is greater than a first power threshold, then controlling the plurality of fuel cell systems to be activated simultaneously includes: judging whether the required power is greater than a second power threshold value, wherein the second power threshold value is greater than the first power threshold value; and determining the output power of the first fuel cell system and the second fuel cell system according to the judgment result.
When the required power is greater than the first power threshold, it may be further determined whether the required power is greater than a second power threshold, which is greater than the first power threshold, and then the output powers of the first fuel cell system and the second fuel cell system may be determined according to the determination result.
