Abstract:
1. A control apparatus for starting a fuel cell vehicle comprising: a fuel cell for supplying electric power to a load; an electric power storage device for assisting a supply of electric power to said load and for storing energy generated by said fuel cell; a first detector which detects a terminal voltage of said electric power storage device; a second detector which detects an output voltage of said fuel cell; a fuel cell driving device for supplying reaction gases and for driving said fuel cell; and a current limiting device programmed to limit an output current from said fuel cell, wherein at the time of starting the fuel cell, said electric power storage device supplies electric energy to said fuel cell driving device and said current limiting device is programmed to prohibit said fuel cell from outputting said output current until said output voltage of said fuel cell reaches a predetermined voltage, and after said output voltage rises to more than the predetermined voltage, said current limiting device is programmed to limit 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 said terminal voltage of said electric power storage device, which is calculated by subtracting said terminal voltage of said electric power storage device from said output voltage of said fuel cell, reaches a predetermined voltage difference.
