Abstract
A combined fuel cell/gas turbine power generation system includes a fuel cell, a reformer connected to the fuel cell for producing a hydrogen rich reformed gas by steam reforming and feeding the reformed gas to the fuel cell, an air compressor having an electric motor which drives the air compressor, the air compressor compressing air taken from open air and feeding a pressurized air to the fuel cell, a gas turbine which is connected to the fuel cell and generates power using, as a working fluid, an exhaust combustion gas from the reformer obtained by burning an off gas and off air from the fuel cell, and a generator which is coaxially connected to the gas turbine and driven by the axial output power of the gas turbine, the generator generating power with the axial output power of the generator, the output power of the generator driving the electric motor in the air compressor.
