A fuel cell system includes a fuel cell module comprising an anode section and a cathode section, a water gas shift reactor (WGSR) configured to receive an anode exhaust stream including carbon monoxide and steam and to output a WGSR exhaust stream comprising carbon dioxide and hydrogen, a condenser configured to receive the WGSR exhaust stream, to condense water in the WGSR exhaust stream, and to output a condensed water stream and a dried gas stream, a gas separation assembly configured to separate the dried gas stream into (i) a carbon dioxide stream comprising carbon dioxide and (ii) an output gas stream, and a cooling vessel coupled to the WGSR. The cooling vessel is configured to receive at least a portion of the condensed water and the carbon dioxide stream, to vaporize the condensed water stream using heat from the WGSR, and to output a humidified carbon dioxide stream.

Water gas shift reactor cooling assembly for a fuel cell system

A humidity transfer assembly includes a pressure vessel and a humidity transfer device disposed in the pressure vessel. The humidity transfer device includes an enclosure, a first inlet line fluidly coupled to the enclosure and configured to supply anode exhaust thereto, a first outlet line fluidly coupled to the enclosure and configured to output anode exhaust therefrom, and a second inlet line fluidly coupled to the enclosure and configured to supply feed gas thereto. The humidity transfer device is configured to transfer steam from anode exhaust to feed gas and to output feed gas into the pressure vessel.

Humidity transfer assemblies for fuel cells and higher-temperature electrochemical systems

A cooling plate assembly includes an anode half-plate having an anode upper surface and an opposing anode lower surface, and a cathode half-plate having a cathode upper surface and an opposing cathode lower surface, the cathode lower surface configured to engage the anode upper surface. The assembly further includes a cooling tube disposed between and engaging the anode upper surface and the cathode lower surface.

Two-phase water cooling in an electrochemical hydrogen separator

A fuel cell system includes an anode configured to output an anode exhaust stream comprising hydrogen, carbon dioxide, and water; and a membrane dryer configured to receive the anode exhaust stream, remove water from the anode exhaust stream, and output a membrane dryer outlet stream. The membrane dryer includes a first chamber configured to receive the anode exhaust stream; a second chamber configured to receive a purge gas; and a semi-permeable membrane separating the first chamber and the second chamber. The semi-permeable membrane is configured to allow water to diffuse therethrough, thereby removing water from the anode exhaust stream. The membrane dryer may further be configured to remove hydrogen from the anode exhaust stream.
