Patent ID: 8034497

Claim:
A control device of a vehicular fuel cell system, comprising: a warm-up output control section configured, when the fuel cell system is started up under a low temperature condition necessary for warm-up of a fuel cell stack and when the fuel cell stack of the fuel cell system is warmed up, to cause the fuel cell stack to generate electric power to allow predetermined warm-up electric power to be drawn; and a run permission section configured to determine, during a period wherein the warm-up electric power is drawn by the warm-up output control section, whether the fuel cell stack assumes a predetermined warm-up condition on a basis of one of (1) a voltage value and (2) an electric current value of the fuel cell stack, wherein when a determination is made that the fuel cell stack assumes the predetermined warm-up condition, the run permission section is configured to provide a vehicle with a run permission, (1) when the voltage value of the fuel cell stack is equal to or more than a run available voltage value that is necessary before the vehicle may commence travel, wherein the run available voltage value is obtained from predetermined current/voltage characteristics showing a relationship between the electric current value of the fuel cell stack and the run available voltage value at a temperature at which an output value of the fuel cell stack is available to provide the vehicle with the run permission, or (2) when the electric current value of the fuel cell stack is equal to or less than a run available current value that is necessary before the vehicle may commence travel, wherein the nm available current value is obtained from predetermined current/voltage characteristics showing a relationship between the voltage value of the fuel cell stack and the run available current value at a temperature at which the output value of the fuel cell stack is available to provide the vehicle with the run permission.
