The power generation control system according to claim 1 , wherein the control device determines a fuel cell system to be operated among the plurality of fuel cell systems on the basis of a result of comparing the required power with a threshold value. 3. The power generation control system according to claim 2 , wherein the control device determines a fuel cell system to be stopped among the plurality of fuel cell systems when the result of comparing the required power with the threshold value indicates that the required power is less than the threshold value. 4. The power generation control system according to claim 1 , wherein the control device determines a fuel cell system to be operated or stopped among the plurality of fuel cell systems on the basis of both the required power and the state of the battery. 5. The power generation control system according to claim 2 , wherein the control device selects a fuel cell system to be operated from among the plurality of fuel cell systems on the basis of a result of comparing a power generation time period of each of the plurality of fuel cell systems with a threshold value. 6. The power generation control system according to claim 5 , wherein the control device selects a fuel cell system to be stopped from among the plurality of fuel cell systems whose power generation time periods are greater than or equal to the threshold value indicated in the result of comparing the power generation time period of each of the plurality of fuel cell systems with the threshold value. 7. The power generation control system according to claim 2 , wherein the control device selects a fuel cell system to be operated from among the plurality of fuel cell systems on the basis of a result of comparing temperatures of the plurality of fuel cell systems with a threshold value. 8. The power generation control system according to claim 7 , wherein the control device selects a fuel cell system to be stopped from among the plurality of fuel cell systems when the result of comparing the temperatures of the plurality of fuel cell systems with the threshold value indicates that the temperature is greater than or equal to the threshold value. 9. The power generation control system according to claim 1 , wherein the control device selects a fuel cell system to be operated or stopped from among the plurality of fuel cell systems on the basis of a result of comparing charge rates of fuel cells provided in the plurality of fuel cell systems with a threshold value. 10. A power generation control system comprising: a plurality of fuel cell systems mounted in an electric device that operates using electric power; a battery mounted in the electric device; and a control device configured to control each of the plurality of fuel cell systems on the basis of states of the plurality of fuel cell systems, a state of the battery, and required power of the plurality of fuel cell systems, wherein the control device determines a fuel cell system to be operated among the plurality of fuel cell systems on the basis of a result of comparing the required power with a threshold value, and wherein the control device selects a fuel cell system to be operated from among the plurality of fuel cell systems on the basis of a result of comparing a power generation time period of each of the plurality of fuel cell systems with a threshold value. 11. A power generation control system comprising: a plurality of fuel cell systems mounted in an electric device that operates using electric power; a battery mounted in the electric device; and a control device configured to control each of the plurality of fuel cell systems on the basis of states of the plurality of fuel cell systems, a state of the battery, and required power of the plurality of fuel cell systems, wherein the control device determines a fuel cell system to be operated among the plurality of fuel cell systems on the basis of a result of comparing the required power with a threshold value, and wherein the control device selects a fuel cell system to be operated from among the plurality of fuel cell systems on the basis of a result of comparing temperatures of the plurality of fuel cell systems with a threshold value.
