Abstract

The power generation system comprises a fuel cell unit adapted to generate electric power using a hydrocarbon-containing gas. A water-gas shift reactor is adapted to receive flue gas from the fuel cell unit and convert carbon monoxide contained in the flue gas into carbon dioxide and hydrogen. A cryogenic carbon dioxide capture unit is adapted to receive flue gas from the water-gas shift reactor and remove carbon dioxide therefrom. A recycle line recycles carbon dioxide-depleted flue gas to the fuel cell unit.
