Abstract:
A control apparatus for starting a fuel cell vehicle comprising:a fuel cell for supplying electric power to a load; a capacitor for assisting a supply of electric power to said load and for storing generated energy by said fuel cell; a fuel cell driving device for supplying reaction gases and for driving said fuel cell; and a current limiting device for limiting an output current from said fuel cell; wherein, at the time of starting the fuel cell, said capacitor supplies electric energy to said fuel cell driving device and said current limiting device prohibits said fuel cell from outputting an output current until an output voltage of said fuel cell reaches a predetermined voltage, and wherein, after said output voltage rises to more than the predetermined voltage, said current limiting device limits said output current of said fuel cell to below a predetermined current value until a difference between said output voltage of said fuel cell and a terminal voltage of said capacitor reaches a predetermined voltage difference.
