<P>PROBLEM TO BE SOLVED: To provide a control apparatus for reducing exhausted amount outside a vehicle of fuel gas which exists in a circulation path inside the vehicle, and increasing an exhausting amount of impure gas existing in the circulation path, outside the vehicle. <P>SOLUTION: The control apparatus 9 drives a travel motor 8 for the vehicle by the power generated by a fuel cell stack 6 for making oxidization gas which contains fuel gas containing hydrogen and oxygen have an electrochemical reaction. The control apparatus 9 is equipped with: a storing section for storing the density information for the gas which is detected by a gas sensor 66 which is arranged in the circulation path P4 for supplying the fuel gas which was not used for power generation to the fuel cell stack 6; and a control section for purging the impure gas which is accumulated to the circulation path P4 by releasing an air ejection valve 7 which is arranged in the circulation path P4, based on the density information that is stored to the storing section. <P>COPYRIGHT: (C)2010,JPO&INPIT |
