Abstract
A fuel cell system and an operation method thereof are capable of re-starting the system reliably even after the system has been tilted to or beyond a predetermined limit. The fuel cell system includes a fuel cell having an anode and a cathode. A tilt sensor detects a tilt of the fuel cell system not smaller than a predetermined limit, and a memory stores a record that the fuel cell system was tilted to or beyond the predetermined limit. When the fuel cell is started thereafter, the fuel cell is started in a recovery mode if there is a record of a tilt not smaller than the predetermined limit in the memory. The fuel cell is not started, however, if a tilt time since the detection of the tilt of the fuel cell system not smaller than the predetermined limit is not smaller than a first predetermined value.
