Abstract
A fuel cell system including a fuel cell module comprising an anode section configured to output an anode exhaust stream, a first junction configured to split the anode exhaust stream into an anode recycle stream and a system outlet stream, and an ejector. The ejector comprises a low pressure inlet configured to receive a suction stream comprising a first portion of the anode recycle stream, a motive inlet configured to receive a motive stream comprising a second portion of the anode recycle stream, and an outlet configured to output an ejector output stream. The anode section is configured to receive an anode input stream that comprises the ejector output stream.

A fuel cell system comprising:
- a fuel cell module comprising an anode section configured to output an anode exhaust stream;
- a first junction configured to split the anode exhaust stream into an anode recycle stream and a system outlet stream;
- a second junction configured to split the anode recycle stream into a first portion and a second portion;
- a cooler configured to cool and remove water from the second portion of the anode recycle stream;
- a compressor configured to:
- receive and pressurize a fuel stream comprising the dried second portion of the anode recycle stream and a fresh fuel stream;
- and
- output a pressurized fuel stream;
- a carbon dioxide separation stage configured to remove carbon dioxide from the pressurized fuel stream and output a motive stream, the carbon dioxide separation stage comprising a molten carbonate electrolyzer system or an amine scrubber system;
- and
- an ejector comprising:
- a low pressure inlet configured to receive a suction stream comprising the first portion of the anode recycle stream;
- a motive inlet configured to receive the motive stream;
- and
- an outlet configured to output an ejector output stream;
- wherein the anode section is configured to receive an anode input stream that comprises the ejector output stream.
