Fuel cell system and method of controlling same

摘要

A fuel cell system includes a fuel cell configured to generate electric power with a fuel gas and an oxygen gas fed to the fuel cell and to discharge exhaust gas including CO2 as a result of generating the electric power; a CO extraction part configured to reduce the CO2 in the exhaust gas fed to the CO extraction part to CO, the CO extraction part including a processing container fed with the exhaust gas and a CO2 adsorbing member provided in the processing container and formed of an oxide having an oxygen deficiency; and a CO recycling part configured to feed the extracted CO to the fuel cell as part of the fuel gas.
