摘要： A contactor electrically connects and disconnects a fuel cell from a load. When a failure-detecting mode for detecting a closing failure of a contactor is initiated, an opening command is transmitted to the contactor, and a DC/DC converter connected to a motor changes the load voltage. Then, the load voltage and a fuel cell voltage are compared with each other. If the contactor is in a normal open state, as a result of the opening command, the fuel cell voltage is constant, whereas the load voltage of the DC/DC converter decreases, thereby producing a voltage difference. A closing failure of the contactor is determined when it is detected that the fuel cell voltage is substantially equal to the load voltage.

摘要： When a control device detects a request for stopping power generation of a fuel cell, electrical energy discharged from the fuel cell is supplied to an energy storage and other electrical devices such as an air compressor. At this time, electrical energy is supplied preferentially to the other electrical devices. Accordingly, discharge/charge losses in the energy storage can be reduced, compared to a technique in which an energy storage is charged preferentially at the time of stopping power generation of a fuel cell.
