FUEL CELL SYSTEM AND CONTROL METHOD FOR THE SAME

摘要

A fuel cell system includes a fuel cell, an air supplier, an air passage connected to the fuel cell, air supplied from the air supplier flowing in the air passage, a bleed passage branched off from the air passage on a side upstream of the fuel cell and joining the air passage on a side downstream of the fuel cell, part of the air supplied by the air supplier flowing in the bleed passage in such a manner as to circumvent the fuel cell, a bleed valve provided in the bleed passage, the bleed valve regulating the amount of air flowing in the bleed passage, an air supplier control unit which controls the air supplier to supply a predetermined amount of air, a wetness reduction determination, unit which determines whether or not it is necessary to reduce a degree of wetness of the fuel cell, and a bleed amount control unit which reduces an opening of the bleed valve when the degree of wetness of the fuel cell needs to be reduced.
