COMBUSTION SYSTEM HAVING A FUEL CELL AND A CARBON CAPTURE SYSTEM

A combustion system includes a topping cycle (102) generating a flow of exhaust gas and a bottoming cycle (104). The combustion system further includes a fuel cell (106) including an anode side (112), a cathode side (116), and an electrolyte (114). The combustion system further includes a heat recovery steam generator (32) (HRSG) that receives the exhaust gases (34) from the cathode side (116) via a cathode outlet line (146). The HRSG (32) generating a flow of steam for use in the bottoming cycle (104). A bypass line (168) extending from the cathode inlet line (118) to the cathode outlet line (146). A carbon capture system (108) fluidly coupled to the HRSG (32) via an HRSG (32) outlet line. The carbon capture system (108) removing a second portion of pollutants from the exhaust gas.
