POWER GENERATION SYSTEM AND OPERATING METHOD THEREFOR

A power generation system includes: a fuel cell (11); a casing (12) accommodating the fuel cell (11); a controller (102); a supply and exhaust mechanism (104) including an exhaust passage (70) and an air supply passage (78); and a damage detector, provided in at least one of the supply and exhaust mechanism (104) and the casing (12), configured to detect damage to the exhaust passage (70). The controller (102) performs control to stop operation of the power generation system when the damage detector detects damage to the exhaust passage (70).
