The present invention is to continuously supply power to outside even when a disorder is detected in a sensor to measure the power supplied to outside. The present invention also relates to a control method of a fuel cell mounted in a vehicle and an external power supply system to supply power from a secondary battery to outside. When a disorder is detected in a sensor to measure power supplied from a power wiring, to which a fuel cell and a secondary battery can be connected, to outside: (a) when a decrease is detected in the electricity storage quantity of the secondary battery, external power supply is conducted by increasing the power generation quantity of the fuel cell to stop the decrease in the electricity storage; and (b) when an increase is detected in the electricity storage quantity of the secondary battery, external power supply is conducted by decreasing the power generation of the fuel cell to stop the increase in the electricity storage quantity.

    본 발명은, 외부에 급전되는 전력을 계측하는 센서의 이상을 검지한 경우에 있어서도 외부에의 급전을 계속시키는 것을 과제로 한다. 차량에 탑재된 연료 전지 및 이차 전지로부터 외부에 전력을 공급하는 외부 급전 시스템의 제어 방법이다. 연료 전지와 이차 전지가 접속 가능한 전력 배선으로부터 외부에 급전되는 전력을 계측하는 센서의 이상을 검지한 경우에 있어서, (a) 이차 전지의 축전량의 감소가 검지되는 경우에는, 축전량의 감소를 멈추도록 연료 전지의 발전 전량을 증가시켜서 외부 급전을 행하고, (b) 이차 전지의 축전량의 증가가 검지되는 경우에는, 축전량의 증가를 멈추도록 연료 전지의 발전 전력을 감소시켜서 외부 급전을 행한다.
