FUEL CELL SYSTEM

摘要

A fuel cell system capable of warming up a fuel cell while preventing a rush current. A controlling device (90) changes over the connection/disconnection between a fuel cell (40) and a short circuit (80) by a shorting relay (81). The controlling device (90) spends, before switching the short circuit relay (81) from disconnection to connection at cold starting, oxidizing gas remaining in the cathode of the fuel cell (40) by driving auxiliary devices to generate an oxidizing gas-deficient state. Then, the controlling device (90) switches an FC relay (61) from on to off and the short circuit relay (81) from off to on to thereby complete the preparation for supplying a short-circuit current.
