Sawada further teaches the processor is configured to compare an average temperature of the first set of the hydrogen tanks whose distance from the stack cooling module is greater than a first reference distance among the one or more hydrogen tanks with an average temperature of a second set of hydrogen tanks whose distance from the stack cooling module is closer than the first reference distance among the one or more hydrogen tanks (paras. 0009, 0056; Figs. 4-6). Regarding claim 8 , Sawada teaches all the claimed limitations as stated above in claim 7. Sawada further teaches the processor the processor is configured to, in response to a case where the average temperature of the hydrogen tanks whose distance from the stack cooling module is greater than the first reference distance among the one or more hydrogen tanks is the same as the average temperature of the hydrogen tanks whose distance from the stack cooling module is closer than the first reference distance among the one or more hydrogen tanks, determine that temperatures of the one or more hydrogen tanks are uniformly controlled (paras. 0009, 0056; Figs. 4-6). Regarding claim 9 , Sawada teaches all the claimed limitations as stated above in claim 7. Sawada further teaches the processor is configured to, in response to a case where the average temperature of the hydrogen tanks whose distance from the stack cooling module is greater than the first reference distance among the one or more hydrogen tanks is greater than the average temperature of the hydrogen tanks whose distance from the stack cooling module is closer than the first reference distance among the one or more hydrogen tanks, control the one or more angles of the selected one or more angles of the air guide to be greater than the selected one or more angles (paras. 0009, 0056; Figs. 4-6). Regarding claim 10 , Sawada teaches all the claimed limitations as stated above in claim 6. Sawada further teaches the processor is configured to, in response to a case where the outside air temperature is higher than a second reference value, to block the air passing through the stack cooling module from flowing into the one or more hydrogen tanks by controlling the one or more angles of the air guide (paras. 0009, 0056; Figs. 4-6). Regarding claim 11, Sawada teaches all the claimed limitations as stated above in claim 6. Sawada further teaches the first reference value is a temperature at which an output of the fuel cell stack is limited, and the second reference value is a temperature at which the fuel cell stack is shut down (para. 0035). Regarding claim 12 , Sawada teaches all the claimed limitations as stated above in claim 1. Sawada further teaches the processor is configured to determine whether an output of the fuel cell stack is greater than a first reference value, and in response to a case where the output of the fuel cell stack is greater than the first reference value, configured to block the air passing through the stack cooling module from flowing into the one or more hydrogen tanks by controlling the one or more angles of the air guide (paras. 0009, 0056; Figs. 4-6).
