FUEL CELL SYSTEM AND METHOD FOR OPERATING SAME

摘要

Since a conventional fuel cell system has a structure in which a filter in an exhaust flow path for fuel exhaust gas is heated by a heater, the exhaust flow path can be prevented from being blocked due to freeze, but there has been the problem of extended startup time. A fuel cell system (F1) comprises a fuel cell (FC) for generating electricity by reacting a fuel gas with an oxidant gas and an exhaust flow path (42) for exhausting the fuel exhaust gas exhausted from a fuel electrode (16) of the fuel cell (FC) to the outside. The fuel cell system (F1) is equipped with a movable filter device (50) disposed in the exhaust flow path (42), so that by activating the movable filter device (50), water and foreign particles adhering to the filter are quickly scattered by rotational centrifugal force and vibration, thereby preventing the exhaust flow path (42) from being blocked by the clogging by water freeze and foreign particles and also reducing startup time.
