Combined cycle in fuel cell power generating facility

Abstract

Abstract PURPOSE:To utilize exhaust gases and thermal energy effectively and to improve the overall efficiency by providing a gas turbine and a generator on a phosphate electrolyte fuel cell power generating facility so as to perform a combined cycle. CONSTITUTION:The exhaust gas at the cathode 2 side of a fuel cell proper 5 is separated from moisture by a separator 16, and is burned by a reforming burner 17 together with the air from a turbo compressor 18. On the other hand, the exhaust gas at the anode 3 side is separated from moisture by a separator 21, is mixed with the exhaust gas from the reforming burner 17 by a mixer 26, is introduced into a gas turbine 29 through a gas regulator valve 28, and drives a turbine generator 30 to generate electricity. Furthermore, this exhaust gas is used for the turbo compressor 18 through gas regulator valves 22, 31. Accordingly, the exhaust gases at the cathode side and the anode side of the cell 5 are utilized to drive the turbine generator 30, thereby the overall efficiency of the whole power generating facility can be remarkably improved.
