A fuel cell system and an abnormality detecting method therefor is provided. The fuel cell system includes: a fuel cell that includes at least one fuel-cell cell having an anode, a cathode and an electrolyte membrane, an anode-side passage supplying and exhausting fuel gas to and from the anode, a cathode-side passage supplying and exhausting oxidation gas to and from the cathode, a voltage detecting unit detecting a fuel cell voltage, a suppressing unit setting a suppression state where, after terminating normal power generation, introduction of the fuel and oxidation gas to the anode-side and cathode-side passages and emission of the fuel and oxidation gas from the anode-side and cathode-side passages to outsides are suppressed as compared with those during the normal power generation; and an abnormality detecting unit, after setting the suppression state, detecting abnormality of the fuel cell system based on the detected voltage or a variation thereof. |
