Abstract
Various hot box fuel cell system components are provided, such as heat exchangers, steam generator and other components.
Claims7
A heat exchanger, comprising:
- a top enclosure comprising a finger plate;
- a bottom enclosure comprising a finger plate;
- and
- a corrugated sheet between the top and bottom enclosure;
- wherein the heat exchanger is configured such that a first fluid flows on one side of the corrugated sheet and a second fluid flows on an opposite side of the corrugated sheet.
2 more elements
A fuel cell system, comprising:
- a hot box;
- a fuel cell stack located in the hot box;
- a roughly cylindrical anode cooler uni-shell heat exchanger located in the hot box;
- and
- a roughly cylindrical cathode recuperator uni-shell heat exchanger located in the hot box;
- wherein:
- the anode cooler is configured to allow substantially axial fuel cell stack anode exhaust stream and air inlet stream entry into the anode cooler;
- the cathode recuperator is configured to allow substantially non-axial ATO exhaust stream and the air inlet stream entry into the cathode recuperator;
- the uni-shell heat exchangers each comprise a roughly cylindrical corrugated sheet process gas separator, wherein peaks and valleys of the cylindrical corrugated sheet process gas separator are aligned parallel to an axial direction of the cylindrical corrugated sheet process gas separator.
6 more elements
A fuel cell system comprising:
- at least one fuel cell stack or column;
- and
- a cathode recuperator heat exchanger in which an air inlet stream to the at least one fuel cell stack or column is heated by an air exhaust stream from the at least one fuel cell stack or column;
- wherein the air inlet stream outlet of the cathode recuperator heat exchanger is located adjacent to any one or more points in a middle portion of the fuel cell stack or column, such that the air inlet stream exiting the cathode recuperator is directed towards a middle portion of the at least one fuel cell stack or column.
