Abstract
A method includes providing fuel and air to a fuel cell system to generate electric power, an anode exhaust and a cathode exhaust, separating at least a portion of water and carbon dioxide from the anode exhaust received from the fuel cell system to form syngas containing at least 50 molar percent of a mixture of hydrogen and carbon monoxide, recycling a first portion of the syngas output from the exhaust processing system to the fuel cell system, and providing a second portion of the syngas output from the exhaust processing system to a syngas system to generate a product using the syngas.
Claims20
An integrated system, comprising:
- a fuel cell system;
- an exhaust processing system configured to separate at least a portion of water and carbon dioxide from anode exhaust received from the fuel cell system to form syngas comprising at least 50 molar percent of a mixture of hydrogen and carbon monoxide;
- a processing conduit fluidly connecting the fuel cell system to the exhaust processing system, and configured to transfer the anode exhaust output from the fuel cell system to the exhaust processing system;
- a syngas system configured to generate a product using the syngas received from the exhaust processing system;
- a syngas recycle conduit fluidly connecting the exhaust processing system to the fuel cell system, and configured to recycle a first portion of the syngas output from the exhaust processing system to the fuel cell system;
- and
- a syngas conduit fluidly connecting the exhaust processing system to the syngas system, and configured to provide a second portion of the syngas output from the exhaust processing system to the syngas system.
