Patent number: 8216734Abstract: Provided is a fuel cell system which can properly control a refresh operation. A controller controls the refresh operation so that an output voltage does not exceed an avoidance voltage even after the refresh operation. Specifically, the controller estimates the output voltage after the refresh operation from the output voltage before the refresh operation and controls execution of the refresh operation so that the estimated output voltage after the refresh operation does not exceed the avoidance voltage. For example, if before the refresh operation, when judging that the estimated output voltage after the refresh operation does not exceed the avoidance voltage, the controller executes the refresh operation.Type: GrantFiled: January 15, 2009Date of Patent: July 10, 2012Assignee: Toyota Jidosha Kabushiki KaishaInventor: Hideaki Mizuno

Patent number: 8110311Abstract: There is provided a fuel cell system capable of warming up a fuel cell while inhibiting generation of a rush current. A control device switches the connection/disconnection between a fuel cell and a short circuit by a shorting relay. The control device spends, before switching the shorting relay from disconnection to connection during starting at a low temperature, an oxidizing gas remaining in the cathode of the fuel cell by driving auxiliary devices to generate an oxidizing gas-deficient state. Then, the control device switches FC relays from ON to OFF and the shorting relay from OFF to ON to thereby complete the preparation for supplying a short-circuit current.Type: GrantFiled: November 20, 2006Date of Patent: February 7, 2012Assignee: Toyota Jidosha Kabushiki KaishaInventors: Kota Manabe, Kimihide Horio, Hideaki Mizuno, Hironori Noto, Takashi Yamamoto, Tomoya Ogawa
