FUEL CELL SYSTEM

A fuel cell system includes a fuel source configured to provide a fuel input stream, a first carbon dioxide removal system configured to receive the fuel input stream and remove carbon dioxide from the fuel input stream, a fuel cell stack including an anode section having an anode inlet configured to receive an anode input stream, and an anode outlet configured to output an anode exhaust stream, and a cathode section having a cathode inlet configured to receive a cathode input stream, and a cathode outlet configured to output a cathode exhaust stream, an anode exhaust gas recycle system including a second carbon dioxide removal system configured to receive and remove carbon dioxide from the anode exhaust stream, and a combining junction configured to receive the fuel input stream, and the anode exhaust stream, and to output a mixed stream to the anode inlet as the anode input stream.
