Air supply device for fuel cell

摘要

An air supply device for a fuel cell is disclosed which is provided with a displacement compressor 10 for supplying pressurized air as an air source to a cathode through an air supply line connected to the cathode inlet side of the fuel cell I so that a burned gas obtained by burning an anode exhaust gas AG discharged from an anode of the fuel cell may be conducted to the intake side of an exhaust gas turbine 8 for driving the displacement compressor, and so that air may be supplied to the cathode 2 by driving the displacement compressor 10 with the exhaust gas turbine that operates with the burned gas of the anode exhaust gas.
