Combined cycle in fuel cell generation unit

Abstract

Abstract PURPOSE:To improve all-round efficiency of fuel cell generation unit by effectively using thermal energy such as an exhaust on the anode-and cathode sides of the fuel cell proper and reaction heat of the fuel cell proper emitting outside of the system of the fuel cell generation unit in the system of a phosphate acid electrolyte fuel cell. CONSTITUTION:Reaction heat generated by electrochemical reaction inside of a fuel cell proper 5 is absorbed by cooling water in a fuel cell cooler 23 and the heated cooling water is introduced into a steam generator 10 to be separated into steam and a drain. Said steam is used for a steam turbin 29 through a steam regulating valve 28 to drive the steam turbin 29 for generating electricity with a turbin generator 30. The exhaust on the anode side and the cathode side of the fuel cell proper 5 is mixed by an exhaust mixer 26 for being effectively used in a steam heater 32 for heating the steam generated from the steam generator 10 for driving a steam turbine 29 and further for improving all-round efficiency.
