Control device of vehicular fuel cell system and related method

A control device of a vehicular fuel cell system, comprising:

• a warm-up output controlling means, when a fuel cell system is started up under a low temperature condition and in case that a fuel cell stack of the fuel cell system is warmed up, for controlling the fuel cell stack to generate electric power to allow predetermined warm-up electric power to be taken out;
• and
• a run permission providing means, while discriminating whether the fuel cell stack assumes a predetermined warm-up condition on the basis of one of a voltage value and an electric current value of the fuel cell stack during a period wherein the warm-up electric power is taken out by the warm-up output controlling means, for providing a vehicle with run permission when discrimination is made that the fuel cell stack assumes the predetermined warm-up condition.

A method of controlling a vehicular fuel cell system, the method comprising:

• taking out predetermined warm-up electric power by controlling the fuel cell stack to generate electric power, when a fuel cell system is started up under a low temperature condition and in case that a fuel cell stack of the fuel cell system is warmed up;
• and
• providing a vehicle with run permission when discrimination is made that the fuel cell stack assumes a predetermined warm-up condition, while discriminating whether the fuel cell stack assumes the predetermined warm-up condition on the basis of one of a voltage value and an electric current value of the fuel cell stack during a period wherein the warm-up electric power is taken out.
